Cadillac DeVille

    Your door locks problem is electrical, and unrelated to the ignition problem. I doubt the new key will fix the door lock problem at all, but it should give you a smooth ignition switch.

    I had a 90 Deville from new........The locks were always hard to turn!
    Much easier to use the push button panel on the outside of door
    to unlock. Must of been the plunger mechanism for the power locks
    that made it hard to turn key.
    Quite a pain ! Sure glad my 96 and later Caddies had the remote!

    I would say your ignition key and/or switch in the column is getting worn out. Too bad you didn't have the key code. A locksmith could make ya a new key for it. That would be your best way out. Can you track the car back to the selling dealer?
    I have had a few ignition switches stop working altogether (unable to turn) in some of my GM winter rats.

    Problem is a 90 Cad has the "pellet" in the key. Pretty $pendy nowadays to have remade. I can just imagine how much it would cost to
    replace ign. switch and key.

    Just traded my 98 Deville for a 2004 model. For some reason the 04 seems to have a little less acceleration power than the 98. I have used premium gasoline in the 04 since purchasing and always used premium in the 98. Think the compression ratio rating in the 04 is a little lower than the 98, would that be the reason? Could promptness in downshifting of the transmission have something to do with it? Perhaps just my imagination since the soundproofing in the 04 seems to insulate the cabin more in the 04 than the 98.
    Any feedback from others who owned 97-99 Devilles and now own 2000 models or later will be greatly appreciated.
  • nvbankernvbanker Posts: 7,285
    A "little less" acceleration or power would be anticipated in a brand new, not yet broken in, car and shouldn't be a concern. The car will hit a stride point somewhere between 15,000 and 20,000 miles, when acceleration and power should be optimal. Right now, it's very tight. Plus, the computer is calibrating for optimal performance and driving conditions.

    Lastly, there are all kinds of variables between the 98 and the 04, like weight, drag, tires, equipment changes, they may look alike, but they are very dissimilar cars, so it's very possible that your performance and mileage may vary.

    I have had 89/90/96/02 and currently a 03.... Devilles.

    My 90 with the 4.9? ran like a scalded dog and up to 100k plus troublefree miles. When I got my 96 with that 4.6 N-star that required premium fuel and was 250?hp vs.the 180?hp of the 90 I
    felt CHEATED !

    The 90 would "walk" my buddies 5.0 Mustang outta the hole and
    down to the next stop light with the Bose playing and the AC on!
    Also would BURN the rf Michelin to a cloud of smoke if not careful!

    The 96 was a PIG off the light and the traction control was a PIA
    till I found the disable button in the glove box.
    It would do a minor burn out if pushed tho. It also served me well
    to 100k miles till traded for my 02.

    My 02 I only had for a few months because the "BOSS" said the dark
    blue interior was too hot ! She picked it out tho.......
    So I never had a chance to really pound on it..........

    My 03 even with 275 hp seems no faster than the 96 with 250? hp.
    Sure is nice to use any cheap pump gas tho. The 96 would buck, stall,
    ping on anything but premium.

    I assume its the nature of the beast esp. with the DOHC motors to
    not hit the sweet spot in power till the RPMs are up there.
    I liked the 90 the best outta all of them for power at any range!

    All of them would cruise 80 mph or so easily all day long and
    spank a beemer, benz, etc. on the street or hi-way with 20k change
    in my pocket and never have spendy maint. visits at a dealer either!

    But getting 20 mpg plus all day long in a full size v-8 powered
    CADDY is better than a appliance cam-cord anyday !

    All in all I have had NO regrets with any of my Caddy purchases.
  • boomer1bboomer1b Posts: 348
    My mom has a 98 Deville with about 50k miles.
    It runs the same as the 96 or 03.

    She wants a SUV now and likes that HUGE sunroof
    on the Caddy SRX. She assumes that it is smaller than her Deville.thus easier to drive.
    Another plus is she likes that you sit higher up than in the car and can see more easily plus the extra open space to haul her dog,gear and the grandkids around.

    Hopefully she gets the V-8 N-star powered one !
  • sls002sls002 Posts: 2,788
    The 96 northstar should have been 275 hp - 300 lb-ft of torque. The 4.9 was 200 hp/275 lb-ft.
  • boomer1bboomer1b Posts: 348
    Did some checking because my old memory is getting foggy !......LOL

    My 90 had a 4.5 180 hp.
    The 96 indeed did have 275. Same as my 03 !

    But still the 90 had the best seat of the pants performance !
  • sls002sls002 Posts: 2,788
    One thing that GM does to some engines is a non-linear throttle response. I think that the northstar engines are linear. The older engines may have been non-linear. What this means is that if you pust the accelerator pedal down 1/4 of the way, the throttle should open 1/4 (linear), but may open 1/2 (non-linear). The seat of the pants feel is great off the line power with non-linear throttle response.

    One thing I know, my supercharged 95 Riviera would always engage the traction control on icy roads when starting from a dead stop. My Seville does not unless I push too hard on the accelerator.
  • nvbankernvbanker Posts: 7,285
    the General does seem to like that sudden tip-in, or at least did several years ago....
  • dale1922dale1922 Posts: 3
    99 Deville takes 3 to 5 seconds of cranking before it starts when warm. Problem occurs after engine has been sitting for 15 minutes. Engine starts fine when cold (after sitting overnight) or when hot (within a few minutes of shutting it off). Any suggestions for the most likely source of the problem?
  • sls002sls002 Posts: 2,788
    Have dealer check the fuel pressure regulator. It may be leaking, flooding the engine or otherwise making the car hard to start.
  • dale1922dale1922 Posts: 3
    Thanks, sls002. Your long distance diagnosis was right on target. Car starts easily after a new fuel pressure regulator was installed.
  • sls002sls002 Posts: 2,788
    My 98 Aurora (small northstar V8) did the same thing, so I suspected that the fuel pressure regulator was a good place to start.
  • bremertongbremertong Posts: 436
    Traded a 98 De Ville with 39,000 miles for a 2004
    De Ville with 15000 miles in July.

    Some observations: Car seems to loose a few mph
    after cruise is engaged and cruise light comes on. is this common in the current model De Ville? Some of the standard features in the 98 are not in the 2004 model, Examples include: cup holders in center arm rest, electronic trunk lock, and heated front seats.

    I was a little surprised that the automated trunk lock was not standard on the 2004 De Ville s. I never used the heated seats on the 98
    so haven't missed them on th 04. Never used the
    arm rest cup holders in the arm rest of the 98 but was a bit surprised that they were not even in the center arm rest of the 04.

    All in all I am satisfied with my purchase, as I was able to get the 04 in the upper $ 20s and the car sold new for 44,650 MSRP (around 41k invoice) less than a year ago.

    Have been intrieged by the new Chrysler 300C, I owned a 1997 Chrysler LHS before owning my 98 De Ville.

    With 340 Horsepower and 390 ft lb of torque, the Chrysler 300C is quite a value with a price tag of around
    $ 40 thousand fully loaded. Still considered my 04 De Ville with 15,000 miles a better overall value for upper $ 20s that I paid.

    Are others in this conference familiar with the new Chrysler 300C? What are your thoughts and reactions? Biggest reaaons I bought Cadillac again were, satisfaction with my previous De Ville, price and the fact that the Chrysler 300C is a new and yet untested product in the market.

    I would be very interested in hearing the reactions of other Cadillac owners regarding new vs older Cadillacs regarding included options and opinions of the new Chrysler 300C and what impact if any it will have on Cadillac in the future.
  • boomer1bboomer1b Posts: 348
    Congrats !!!!!!!

    I really didn't notice anything different in my 02 or 03 base Devilles compaired to my 96.

    The cupholders in the floor/middle of the seat seem much sturdier than the 96 ones mounted in the arm rest. Less spills and wet pant leg !...LOL

    The 96 didn't have bun warmers and they sure are NICE in these cold NY winters !

    My 96 didn't have the hole in the roof either. I had the hole in my 90 and t-tops in the 2 T/As I had and was sick of getting WET !
    Only thru the BOSS nagging did I get the hole in the 02/03s !
    Believe ME....Before I signed the papers on them. I sat thru a lot of carwashes AND hose running on the roof !

    The 02/03 both had the BOSE......NICE ! compared to the 96 which had the reg. am-fm with the cd changer in the trunk. Sounded crummy !
    My 90 had the BOSE cd gold series that POUNDED !
    That was the BEST stock car stereo I had ever heard at the time !!!!!!!!!

    The Northstar engine in all of them is a PIG compared to the 4.5 in the 90.
    That motor was wicked off the line as far as seat of the pants feel ! BURN the rf Michelin tire off from a stop light !
    They all would embarass a lesser lexus,bmw,etc. on the street or hiway with plenty of jingle left in your pocket !

    As far as the new Mopars..The 300 front end looks like a new RR ! That HEMI sounds like fun too !
    But tooo many folks beefing about some things like alignment problems and other issues.
    Interesting car tho !
  • boomer1bboomer1b Posts: 348
    My 02 or 03 don't have the auto trunk pull down !
    My 72 Fleetwood had it !

    I got my fingers pinched a few times and I don't miss it ! Plus the valets, bellman, or non Caddy owners BEATING and slamming down the trunk lid !

    The auto pull down on my moms 98 is broken from nitwits slamming it. I just re-adjusted the striker and unhooked the power wire.
    So now its like a regular trunk lid.............

    Mom is ready for a SRX. Had one for 3 days. She is undecided. Dealer offered $5000 for her mint 98 with under 50k miles.
    Prob. ask 6k and sell it to somebody .
  • bremertongbremertong Posts: 436
    Thanks Boomer, that helped to clarify the issue. I liked the motorized trunk lock and rarely had anyone else using my car. Another feature that my 98 had was an auto release for the emergency brake when shifting out of park. The 2004 De Ville doesn't have that either.

    Regarding trade in value, I received $ 10M for my 98 with 39,000 miles and also in mint condition. I wanted to keep both cars but my garage is only a standard two car and both Cadillacs would have been to crowded.

    Based on my trade value I would suspect you should receive anywhere from $ 8 to 9M for your mothers car with 50,000 miles on it even from a car dealer. Suggest you do a work up value on Edmunds used car value section. I have found it helpful in determining fair trade in values.
  • boomer1bboomer1b Posts: 348
    Forgot about the e-brake release !

    Yea, its a lowball on moms car for sure. But we get the GM employee deal so its expected.
    Didn't really crunch numbers. It was a rough estimate. If she really wanted the car I would go at them for "hard" numbers.

    I want her to get the Northstar bad boy !
    But $55 large !

    Bought 3 Caddies from them so they are pretty good with us.

    I do know better to ask Terry over at RWTV thread for trade value before hand !

    Enjoy your new Caddy !

    An earlier message said that the '04 Deville didn't have cup holders in the center armrest. The front portion of the divider between the seats in my base '03 flips forward and exposes two cup holders. Technically these are not in the armrest but they are fine where they are. The absolute worst cup holders were in the 1992-1999 Buick LeSabres along with the front armrest that constantly broke loose and tilted forward.
    Actually every year something standard seems to go. The '02 Deville had the electrochromatic side mirror along with the power seat belt height adjustment. The mirror became an option and the seat belt height adjustment became fixed. The base radio now only has a CD slot, the cassette is gone except for the Bose radio. My '03 has both.

    What armrest problem? Ihave had a 1993 and 1998 LeSabre and had no problem with the cupholders. It was kind of neat that they could collapse and fold inside the armrest so you didn't have the cupholder sticking out.

    2015 Cruze 2LT, 2014 Malibu 2LT, 2008 Cobalt 2LT

    Decontenting is a common thing for Detroit to do as a model ages - it holds the cost down, and if demand for particular feature isn't strong, and they can save $5 by getting rid of it, they do. That's why I like to buy the second year of any new car model. The first year, they have burn in troubles - the second year, they usually have the glitches out, but haven't started stripping the car of the originally designed features yet.
  • bremertongbremertong Posts: 436
    Thanks nvbanker, as I said previous posts in this conference my 2004 deleted cup holders in center armrest, automatic emergency brake release, automatic trunk lock, automatic fuel door release on remote entry, and heated front seats. My previous car was a 98 De Ville. I owned a 1997 Chrysler LHS before that and almost all items were standard except sun/moon roof and console floor shifter. From what I understand Chrysler is sticking to making most options standard in the new 300C.

    I enjoyed my 98 Cadillac very much but had the opportunity to update
    6 model years and took it. The 2004 is a bit more agile, a bit more quiet on the road and does have some options such as onstar and compass that the 98 did not have.
  • sls002sls002 Posts: 2,788
    In model year 2000 Cadillac moved the Deville onto the stiff FWD body platform that the 1995 Aurora/Riviera introduced. This is where the additional quietness and handling come from.
  • dispencer1dispencer1 Posts: 489
    My 1994 and 1997 LeSabre front armrest continually broke and tilted forward. The dealer replaced the mechanism several times. The thing was bolted between the seats and the plastic pieces that kept it straight constantly broke. Anyway, glad yours held up. The folding cup holders also tilted with the armrest. The ones on the 2000 were much improved.
  • dispencer1dispencer1 Posts: 489
    I agree with you totally. I wanted a 2002, not a 2003, but I wasn't ready to buy till January of this year and most of the 2002's I looked at were ex-rental cars with delivery dates in 2001 so I would have lost more than a year of warranty for a certified '02. I ended up with a 2003 ( originally delivered in November 2002) but I'll follow your advice in the future. I plan to get a 2006 in the spring of 2007 but I'll have to see what changes they actually make in the 2006. So far it looks like just the interior and perhaps some front end changes. I may get a 2007 in the fall of 2007 . Depends how much mileage I put on the 2003. I'm not keeping it past the 6 year 100k warranty. The 2008 will be all new but I won't get one till the 2nd year as per your advice. (I'll probably get a 2009 in the spring of 2010)
  • boomer1bboomer1b Posts: 348
    I kept my 90 & 96 til waay past the warranty and ran them to 100k plus miles. Only a few minor problems along the way.

    Now my trucks are a different story......
    Snowplowing, heavy towing and hauling sure breaks $pendy parts !!!!!
    Them... I usually dump in 3 years for another new one !!!!!

    Check out for the lowest prices I have found for a GMPP warranty.
    Forget those 3rd party ones!
  • nvbankernvbanker Posts: 7,285
    Yes indeed, beware! You get what you pay for, but not necessarily what you deserve with a cheap warranty.
  • dispencer1dispencer1 Posts: 489
    The GMPP is far better than aftermarket 3rd party warranties. It is nice to know that if and when you break down you get towed to a GM dealer and they simply fix what's wrong. You don't have to call around for estimates and get permission from somebody for a repair. With a certified Cadillac you get a 6 year 100k 0 deductible warranty dated from when the car first went into service. This is far better than the other GM "certified" cars and since this warranty would cost more than $2,000 if you simply bought one from a GM dealer before your factory 48/50,000 expired it is a good deal. The dealer I use in Ft. Worth will certify its used Cadillacs for $1,000. This includes the warranty and 4 new Michelin original equipment tires. This is an incredibly good deal. Anyway the GMPP is the way to go.
  • bremertongbremertong Posts: 436
    I didn't realize that the cup holders were under the arm rest in the section below it, didn't realize that section opened but still thought it strange that there would be no cup holders, on doing some basic exploration found them. Very nice and better placed than in my 98 De Ville. Was not all that important to me in that I never used them in my previous car. I miss the auto emergency brake release and the auto trunk lock more than the issue of the cup holders.

    Some not so good news: The cruise control on this car (2004) can only be described as erratic, the green cruise light come on indicating cruise engaged and then the vehicle looses three to five mile an hour before stabilizing speed. The 98 Cruise control was much more stable in that it stabilized at within
    one MPH of message coming on and was easier to read on the dashboard.
    This car just does not seem to have as much power as the 98 especially when floored for two lane passing or for entering highway on ramps.
    I use premium fuel even though not required but that doesn't seem to have helped any.
    I have an appointment at the dealership to address the cruise issue and will also ask about a check for horsepower and torque if such a test is available.
    I saw a Chrysler 300C parked nearby the other day, awesome looking car and at a price of around $ 40,000 fully loaded it is an amazing value. This considering the 340 horsepower and 390 pounds of torque.
    I was happy to get my 2004 De Ville but if things don't work out I would strongly consider a Chrysler 300C as my next car. The biggest issue is newness on the market and no reliability history to go on.
