  • I have a 2000 DeVille. When making a right hand turn, I hear a knock when turning the wheel. I checked the TSB board and the problem was posted there so someone else has had this problem as well. I've had two Front End experts look at the car to no avail. Does anyone know a remedy for this? (also posted on Sedans Message Board)
  • Wondering if others are having this problem. I have an '01 Deville that gets GREAT milage, and is comfortable to sit in. I bought a new 2004 DHS that has seats hard as bricks, and the milage is absolutely horrible. Dealer says milage will improve around 6000 miles which sounds like hogwash to me (unless the cyl walls need the time to ream out ha). No fixes for the seats, but anyone know what's wrong with the milage? I'm wondering if the transmission has something to do with it. Thanks much.

    I own a "98 Concourse Deville, on three occassions I recieved a notice from my local dealer that it is due for service. Within three weeks, wierd things started going wrong with the car. Alerts and warnings about unrelated system failures started occurring, even the antenna suddenly failed to function. This is the third time this has happened after the dealer's notice. Has anyone else experienced this?
  • Well I thought they solved this problem in 2000. I had a 1999 Deville that was a terrific car except!!! The seats would put your legs to sleep. The bolstering be hind the knees was very hard. Both front seats had the problem. Dealer could not help. Sold it, in the first 6 months. Bought a new Volvo S-80, T-6 Super car and super comfort. Poorest service I have ever encountered. Details are to numerous to list. There were no manuals on this car so I sold it and went back to my old stand by a T & C Van. Fourth one since 1984. Rides like a dream and no problems. It 34 months and 54,000 miles still have lots of tread on the tires and the break pads have about half their lining left. Pulled the wheels and checked them.

    Hi;

    I have a 1993 Sedan deVille with 132,000 miles. Have had it for over 10 years and it has been babied. Just got back from a 600 mile trip to North Carolina. This morning the battery was dead (a 28 month old Optima). Charger indicated it was bad. Replaced it with another battery, now the lights on the inside of the car stay on all the time (like a door is open) and it will not lock the doors when shifting into drive. Starts normal. Have not drove it yet. Disconnected the battery a couple of times and still the same result. Suspect the computer is kaput...advice??.. thanks..ds

    I have a 1986 Cadillac DeVille V8-252 4.1L with 230k miles on it.

    It runs fine when cold or cool, but stalls when hot (Las Vegas + 10 miles). It will start back up but, stall again until it is allowed to cool about 5-10 minutes. Then it will run for a while. After a stall, the fuel line still have some pressure on the return side.

    Any ideas?

    Thanks.

    I have a 87 Cadillac Deville V8 4.1 that won't start. I checked if I was getting sparks and I was. Not sure on what I should check next. Any suggestions?

    Hi, I have a 1998 Deville NorthStar and once in a while its tends to make a knock sound on right hand turns. Its not a real bad sound but Im just wondering what it could be and if it could get worse? Did you find anything out? Also I was having problems on start up. Sometimes in the morning on a cold start it pops right off, other times it has to roll over several times. I had the fuel rail and fuel line replaced at the dealer and it seemed to help, but it still does it, just not as much. Please get back to me.
  • arizartarizart Posts: 1
    I am not sure what your problem is but I have to ask, how did you get 230k miles out of a 4.1? Did you do an engine swap? I have the same car and its really been a challenge to keep running at 95k.
  • Does anyone know how to remove the heater Core from a 1995 Cadillac sedan deVille? My husband thinks he has to go through the glove box but isn't sure.Thanks for any help.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,989
    He needs to buy the factory workshop manual to tackle a job like that. He'll regret it if he doesn't get the info directly from the factory manual. It'll tell him where all the hidden bolts and clips and more important the sequence of removal. It's a pretty big job, you don't want to go into it blind.

  • Check the cig. lighter fuses in the trunk fusebox. and make sure there are no shorted lighters and lighter sockets (coins, gum foil etc.) sounds wild but a bad fuse in lighter can cause a dome light to stay on in those Cadillacs, also optimas can and will test or show bad when they are below 10.5 volts. They are usually still good! good luck!

    My 99 Deville had a similar problem under the front end. Under warranty; dealer said replaced hose, and I think there was a recall about it.

    I have a 2000 Deville with 57,000 miles on it. I bought it new and had to have these sensors replaced for the second time. First time under warranty and this time out of pocket repair by cadillac dealer. I am finding out that these sensors were a problem on this year car. Dealer says obviously this is not normal but can do nothing without Cadillac's help. I contacted customer care and filed a complaint but as yet have not heard back. Can anyone shed light on this? I can find no technical service bulletins for this. Did Cadillac provide solution for this and I somehow missed it?

    I have a 1995 Concours. I have close to same problem. Was wondering if you could put normal struts on instead of cadillac struts. Price comparison $900 each for cadillac compared to $350 each for normal

    I have a '98 Deville that will not start on an intermittent basis. Sometimes it will start just fine, turn off the engine and turn the key to hear a click like the solenoid. Turn the key several times and nothing but the click. Wait for a period of time, turn the key and fire right up. The battery has a full charge and tight connections. Could it be cables? solenoid going bad? Or the starter going bad? Any insight would be appreciated.

    I'm sorry I don't have an answer to your question, but I have one for you. My father's window is stuck down and he can't get the door panel off. Knows there's something by the handle keeping it on, but can't see anything. Can you tell us how to remove the door panel?
    Thanks.
  • I am not sure this will work for your father. But, on a few occasions, The driver's side window on my Deville would stick in the down position. The dealer showed me a trick that has so far worked - Hold the window switch in the up position (normally with the left hand) and strike the arm rest sharply with your right fist. Might be worth a try.
  • I have the same problem on my 99 Seville SLS!

    It doesn't "click" it just won't turn over. I had it towed to a dealership (even though it started 1/2 and hour later) and they couldn't duplicate the problem.

    Did you ever get an answer on this one?
  • My Deville is overheating. After I start the engine, 3 to 5mins later the water start to boil. I check the oil for water mix. The oil and water is clean. Do you think I need to replace the heads or just change the head gasket.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,989
    Hard to say. I'm just speculating here but on a super-fast overheat like that, you are perhaps boiling water with exhaust gases. The head gasket could break between the cylinder and a water galley and so you wouldn't get oil contamination but also the head could crack at the exhaust valve allowing exhaust gases directly into the coolant.

    You can actually have the coolant tested for CO contamination, that would tell you right off. A compression test might not pick it up.

    Have you checked the thermostat, just on a long shot?

  • I also have a '98 Deville and I have been recently getting the message "Top Speed - Fuel off" and the engine cuts out. I had it at a dealership in another town since it happened on a trip. Dealer sent it to a local garage. They did the diagnostics and found the the "Throttle speed sensor" had tripped five different times. It tested perfectly, so they cleaned up and leads and I paid them and took my car back for a 300 mile drive home. First the cruise control quit functioning (and anybody who has a solution to this, please write) then that old message started popping up every time I hit 77 or 78 "Top speed - Fuel off" and the engine would cut out, then restart itself a few seconds later. I don't have an owners manual so I cna't look it up. Any advice???
    Thanks,

  • I took out the thermostat. I tried engine blocked seal . It held for about a month.
    Can I check for contamination myself. If It is contaminated do that mean I need to change the head gasket. Someone told me water maybe leaking into the intake
    manifold. I don't know help please.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,989
    No you can't check for CO contamination without the proper tester. If you had water leaking into the oil, your oil would look "milky and gray" when you pulled out the dip stick. There are various tests for a bad head gasket and you probably should have those done by a reputable garage. Solving overheat problems isn't easy sometimes.

  • I've been having a problem with my 98 ETC, 76K miles, as well. I have slowly been losing coolant but no leak could be ever found. I have now over heated twice. Pressure builds and it blows out what ever is left through the overflow hose at the top of the resevoir. What has been happening is that a head gasket failure is allowing coolant into the chamber, not the crank case. If it was in the crank case, your oil dip stick would be a little "foamy". That's a sure sign that the coolant is getting in. My problem is coolant is leaking into firing chamber. Question: When you step on it, can white or grey smoke be seen from the exhaust?. You should never see white smoke. You make have a head gasket that is failing. Unfortunately, this is very explensive repair and I'm investing all options. good luck! I'll write again if you respond.

    Once again, the cooling system can be tested for combustion gases.

  • I'm thinking about buying a 2000 DTS with 53,000 miles. Based on your experience sholud I purchase it?
  • Would anyone with experience related to buying used devilles please offer your feedback. I'm thinking about buying a 2000 DTS with 53,000 miles. Based on your experience sholud I purchase it?
  • blkhemiblkhemi Posts: 1,717
    That sounds like that may be a good buy. But as with any used vehicle, take a competent mechanic along with you to inspect it. I have an '03 Deville DTS that has been an amazing vehicle. These are some of the nicest luxury cars you can buy. At a bargain price. The only major problems you're likely to encounter is because this is a 2000 Northstar you'll likely have a minor oil-burning problem. Figure something like 1/2 quart every 1500-2000 miles. Anything above that is abnormal. Oil-burning is typical of the Northstar engine. I wish it were different, but this a very complex engine that has a lot of moving parts, so it's to be expected. Don't be afraid to buy because of that. I've had a Lexus LS 400, A Infiniti Q45, and a Lincoln T-Car (which is the reason I came back to the American standard Cadillac) and they all had some sort of oil-burn or oil-sludge build-up problem. Other than that, you're likely to have a huge gas bill(or is that just me?) because you are going to love laying into that Northstar just to here it sing. But since this later Northstar runs on regular 87, it'll be a little lighter on your wallet. Finally, if the price is right, jump on it. 5 years old and only 53,000 miles sounds to be a winner.

    P.S. Whatever you do , run a Carfax on it if you don't do anything else. Remember my friend, AN OUNCE OF PREVENTION IS WORTH A POUND OF CURE.
