Sure is different from the "bars" on the steering wheel on my 96..............
I like my trucks good old setup on the turn stalk !
My owners manual states that the dealer should be given a chance to solve the problem. If that fails, then contact Cadillac. My guess is that the cruise control module was not the problem, but the service people should have tested the car after the fix to make sure it was working.
They seem to be the "rage" on most new luxo cars nowadays. I note Ford cars have larger buttons.
Confusing to say the least.
My 03 also loses a few MPH too by the time I figure out which is which!
at higher speeds (50 and over). I am wondering if it could be transmission related or a fuel regulator problem.
Customer service at Cadillac referred me to the local Cadillac dealership in that I bought the car from a used car dealer with the best reputation in my home area. I like the idea of persistence rather than threats. My used car dealer has offered to assist so we will see what happens. I have not ever had a similar problem in my previous cars. Last car being a 98 De Ville.
Will check out my cruise control operation to see how much MPH I lose and post.........
Still like the turn signal stalk controls the best!
Come to think of it...Gotta take my truck up to my Alex Bay place tomorrow. 200 mile round trip hi-way cruise. Will check if I lose a few MPH on that one !.............
The 03s are smaller and on the wheel face. Even after 1 year I am still not used to them.........
The 96 I would push the wrong one and change the fan speed or radio station when looking for the acc. function !..........LOL !!!
My 90 had the on-0ff on the dash and the set/acc. on the turn stalk.
between 33 and 36 MPH. It had performed rather well on the 55 MPH highway. On my 98 De Ville it almost never varied more than 1 MPH. Am hoping this will be solved soon is irritating in a car of this quality. My previous cars never did this and some were in the budget category. Am scheduled to have the used car independent dealership that sold me the car drive and test this week, they have also promised to try to get me some help at the Cadillac dealership to solve the problem. Many thanks to all that have taken the time to try to help with this. I will of course continue to keep you posted on my progress.
Pried the keys away from the "boss".......LOL!
I note the cruise varies by as much as 5 mph either way driving uphill or downhill.
Flatland it only varies by 1 mph..........
My 04 GM truck runs steady as a rock. But will shift down OD to 3rd HARD as needed to keep it at 70 or so!
The Deville rarely even comes outta OD......
The 6 buttons on the wheel are all equally well lit. Still a PIA to use................
this performance problem. Any ideas from other conference members appreciated.
My 96 or moms 98 the cruise didn't vary much when set. My 03 is all over the map. It doesn't bother me too much or enough to run to the dealer.
My trucks shifts like mad up and down to maintain speed. Esp. up a steep grade. The Cad hardly shifts at all but the speed varies.......
The most I can figure is the final drive ratio and/or gearing between the 3 of them..........
But if is the cars only issue in the 5-6 years/100k HARD miles I am gonna put too it. I can live with it altho annoying...............
Happy motoring and keep us posted on anything you find out !.................
New Vendor ? Different set up?
The plot thickens....................
On steep grades (>5%), my SLS will engage lower gears. On less steep grades my car will lose 1-2 MPH or so. I found that long steep grades were usually best handled manually (slow trucks, heavy traffic) and I manually shifted to 3rd gear in hopes of keeping the torque converter locked up or at least doing less work. In any case a long grade would result in the coolant temperature increasing above normal by a few degrees.
On downhills, the cruise is not designed to limit coasting. I engage 3rd gear on steep downhills, and even 2nd if the speed limit is less than 50.
Can the downshifting be adjusted without going into sealed parts? I am hesitant to start tearing up the transmission to correct this even though my warranty runs for another three years and 33,000 miles. It would be helpful for those owners with more technical knowledge to suggest what you would do if you were dealing with this type of cruise problem (see messages 1542,1548 & 1552). Many thanks.
one: have you taken the car back and told them that their fix did not work? if not, then do so.
two: see one first: if the service people are at their wits end, ask if they checked the cable that connects to the cruise module. if this cable is sticky/damaged then the cruise control will not function properly.
Having owned a 98 De Ville and never having had this problem I suspect something needs adjustment, no one is quite sure what.
In any case, you need to tell your dealer/service_department that their previous fix did not work. My service department (even for oil changes) inquires if the service was satisfactory. Of course they were in the process of taking over another dealership and unloading the Cadillac franchise...
Has anyone run this by Alcan, a mechanic who answers questions in some discussions? He's usually there if you address him in the "got a technical question" discussion.

I repeat, that the service department that replaced the module must be told that the cruise control still does not function right.
Regarding the cruise light indicators, my 2004 De Ville has two lights, one on the left side of the steering wheel that lights when the cruise system is operative and a second one on the right side of the dash board that lights after the speed has been set. The set light (dashboard)stays on until the brakes are engaged or the main cruise light on the steering wheel is turned off. The problem in my car is that the speed drops as much as seven miles an hour after the set light comes on. In addition, sometimes when I hit the resume acceleration to bring car back to original set speed the car accelerates until I take my finger off the button and then again drops to the the lower speed again rather than retaining the desired set speed. This only occurs approximately 30 percent of the time at other times works the way it was meant to in the owners manual.
Is your appointment at your convience, or is the service department so busy that it takes a week to get an appointment? Our (now defunct) dealership service department could usually get you in within a day or so. Now the Chevy dealer has taken over....
With an intermittent problem, a resolution can be difficult. One question, if its working, does it always work until the next time you start the car? Or will it fail some of the time during a single trip?
One thing for sure, this is Cadillac's problem to solve, not yours. If they can't figure it out, the lemon law should apply -> they should let you have a new car (free if a 2004, or at cost if a 2005). Hopefully it won't come to that.
Many thanks for your continuing interest. Will let you know the final outcome.
Took my 04 Chevy truck on a 200 mile round trip Sat. hauling 30 sheets oc CDX plywood.
Up and down a major hiway. Cruise on 65.
Never varied 1 mph either way.............
Trans. did shift down od to 3rd on major grades.
Swapped off with the "boss" driving the 03 Deville at different points back and forth.
The Caddy varied 5 mph either way............
But the trans. NEVER shifted outta OD......
Aggrivating yes........Trip to the dealer......NAH!
My 96 Deville cruise was rock steady.
My moms 98 is too.........
I wonder if its a design problem, gearing, trans. shift points ????????
THOUGHTS ????
What about shifting into 2 if the speed is low enough and it's losing speed on a grade...
2014 Malibu 2LT, 2015 Cruze 2LT,
The truck would kick down into 3rd to keep speed
at 65. But hauling 500 lbs. or so..........
The "sofa on wheels" just loafed along. Just the speed varied around 5 mph either way.
Rarely did I notice it kick outta OD.
Too busy cranking up the BOSE and feuding with the teenager over what tunes next?........
Geezer music or the "good stuff"....LOL !

as much as five to seven MPH. once again the failures are intermittent, that is not counting the one or two mile an hour decreases. At lower speeds I think it may have something to do with downshifting or torque converter. Can these parts be easily adjusted or does this involve major work or replacement?
Thanks for the Lemon Law web site, I have book marked for future reference.
There are a number of parts that may be faulty and replacing them one by one will take time till the bad one is found. A good service department should be able to do this if you give them the time to do so. On the other hand, if all they are doing is replacing a part because they don't know what else to do, then it may require several trips to the service department before they get the right part replaced. I don't know how good your service department is.
have asked for a CTS as a loaner, customer service coordinator has said she will request one for me. So far as cars being held overnight, how do I protect myself from misuse and or damage while with the dealership? Speak up and ask before seems like a practical approach or is it? I'm not sure how good the service department is in that this is the first problem I have presented them with and so far they have not resolved it. Many thanks for you continuing interest on this as I try to get it corrected.
2014 Malibu 2LT, 2015 Cruze 2LT,
The hassle of filing claims not to mention the inconvenience of lost time at a repair shop
is an annoyance I would like to avoid if at all possible. Guess I've been pretty lucky in that I have had few problems with any of my previous cars, it would be nice if they figure out what to do on a second try.

So if the dealer sold mostly base Devilles last year, thats what they are getting this yeay? That makes sense I suspect that is what mine did as the majority of the Devilles I see around here are the base models as a Concours was fairly rare. BTW, I saw a Diamond White STS with a maroon colored interior today. It was the current model, but I don't think it was a 2000 as Cadillac dropped the maroon interior color for this year. That was the first one of the the current model that I had seen in that combo and it looked pretty nice.
On return to the dealership, the technician made adjustments to the cruise cable and did a few other adjustments to the system. On my way home
I did notice the system was more stable and didn't seem to be loosing speed as it had been doing, still seemed to loose 1 MPH which I can live with. It will take several more days of driving to determine if the system is now satisfactory.
I test drove another 2004 De Ville about a week ago and noticed it was also loosing about 2 MPH after cruise light came on. In my car it has been as much as 7 MPH until to days work.
Thanks Boomer, I think the idea of posting at Cadillac forums is a good idea, am beginning to think that the cruise function in this vintage of Cadillacs (2000-2004) may leave a bit to be desired. Many thanks to the other owners who have been very generous in offering their advice. I will keep you all posted.
They should inspect for air leaks too, as the system uses vacuum to operate the throttle I think. You should let them know that the problem is not fixed so they can think about it or call Cadillac for help.
2014 Malibu 2LT, 2015 Cruze 2LT,
I looked under my hood (2002 Seville LS) and the box controlling the throttle linkage seem not to have a vacuum line at all. There are wires running to it (no speedo cable) and a cable to the throttle. So the throttle must be controlled by a stepper motor.
If the cables leading into the cruise control module are damaged, then erratic results could be expected.
