Cruise Control to stop working?

There is a CR Cont fuse we need to check here is the cruise control wiring diagrams so you can see how the system works with a guide to hep you check the fuse with the fuse locations as well.

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Well the quotes arent to bad, but the fact that the trans is going out after 1100 miles of driving dosent make me happy.

I totally understand. Is there any powertrain warranty that came with the vehicle?

No no warranty, bought it at a car lot as is, but would hope he would give 30 days for anything major. I drove it back home to KY yesterday and its supposed to be at the shop now which the car lot owner is talking about covering half possibly, also giving the option of buying it back. But of course I dont want to give the car back because I love it, so now im wandering if I rebuilt the trans and fix the other stuff (tensioner, shocks, wheel hub) will that be all, or is this just one bad car out of the million I see on the road? Guess its a decision I have to make

After having transmission work done and fixed properly, my cruise still will not engage. They said they cleared all the codes, and still could not get it to work. Is there something they may have missed, or is my cruise really gone bad, seperately from the trans issue that is fixed now??

It was the brake light switch in my car FYI

1999 park avenue cruise control does not work. Fuse OK. Brake lights work. Testing the multifunction turn signal switch indicates the resume switch is not working or open. Will the resume switch cause the entire cruise control system NOT to function.

Looking at the schematic, it should still set even if the resume/accel switch is open. It is normally open in all conditions unless it is depressed. All switches are inputs to the cruise module. If there are any powertrain faults stored, that can inhibit cruise operation, so check for powertrain dtc's. In addition to the stoplamp switch input to the cruise control module, there is also the ABS/TCC switch to consider.

Cruise was working and stepped on brakes and cruise went off. The next time I went to use the cruise it would'nt work.

Unable to reset, none of the buttons work. How to resolve this problem?

Your question is pretty vague. What are you trying to reset? Your owners manual will give you the proper steps. If your dash board is out then it is probably a fuse or connection somewhere. If the buttons themselves just aren't doing anything then it may be a bad connection from the button to the computer or actuator. The buttons sometimes go bad.

Was your's visible? Mine went out after a repaired intake gasket and they have looked for the ground wire that could be loose but have not been ablke to find it.

I have a 1998 park avenue ultra, 3.8 supercharger. The cruise control is inoperative. First the basics, when starting the car, the cruise light will light up. However, when the cruise switch is turned on, the cruise light does not light up. Now for trouble shooting already done: brake lights are all good, servo/regulator motor been replaced, fuse under passenger side dash is good and not blown. The two switches at the brake pedal have been replaced. The lever switchs, turn signals, lights etc all work fine, except cruise wont turn on. I am at ends with what may be wrong. I can find no other forums with this type of forum. any ideas?

Where you able to fix this issue with the cruise control and what was the cause? I am having the same problem. I can get the cruise control to activate only by keeping my foot on the gas pedal and keeping the speed constant but when I let off of the gas the cruise disengages. The fuse is fine, brake lights are fine, I've replaced the cruise control switch/turnsignal lever and swapped out the cruise control module with a used one and it still doesn't work. My mechanic doesn't know what to check anymore besides getting a new module. I searched this issue on the web and have found no other solutions than what I have already tried.

When I engage the cruise control, nothing happens. The cruise light doesn't even come on. I have checked the fuses and they look fine. HELP

Is the cruise on/off switch located in the steering wheel?

The switch is located on the directional signal.

First, you need to have it scanned for trouble codes.

I recently got some work done to my car and the cruise control does not work. Could it be a fuse? Please help I have a 1993 Buick park avenue

check for a vacuum leak or the hoes may be dicconnected to the diapham. you criuse is ran by vacuum. the pump like thing hooked up to the throttle linkage so it should be near the throttle body. make sure the linkage is hooked up.what did they work on.it may also be a fuse. does a criuse light come on the cluster.it will only work above 35 mph also.hope that helps.i t
could be the buttons(maybe?)
the cuise module look like a round can type thing.the end pionting out tword the headlights is rubber and has the linkage stick out

After replacing the cruise control servo and the brake switch, It works perfectly when you first turn it on. If you have to hit the brake or turn it off, it only works intermittently. If you help it with the gas pedal, it will work on and off. The cruise light stays on all of the time, though. I've replaced the servo and the brake switch. What else am I missing?

The engine supplies vacuum to the servos. There is a vacuum tank that stores vacuum as a reserve. There is a vacuum check valve between the engine vacuum harness and CC vacuum harness. It the check valve is bad, the CC will will work erraticly. That is the first thing I would check. If it is good, it could be several other things.

Let me know what you find.

I have a 1993 Buick Park Avenue. It has about 130,000 miles on it. Latly my car has been giving me some difficulties such as it seems like it has no power when speeding up. No matter how hard i push down the gas pedal it speeds up the same. The service engine light only comes on when the car is slowing down or when the car is going about 60 mph. On about two occasions i was accelerating and when the car got up to about 50 mph it just started slowing down even though i was pressing the gas pedal. the car has also stalled about on about 3 different occasions. and about 4-7 days after these problems began occuring my cruise control stopped working. any advice would be helpful. thank you

The first thought that comes to mind is that it sounds like you may have an exhaust converter that is pluged up. That would exsplain why the car lacks the power and could also cause dying issues. What code is setting when the engine light came on. Have you had it scaned for codes? I would be curious to know what code is setting...


Cly

what r the code setting that i should be looking for and how do i find them

Take the car to a local auto parts store most of them have something that they can hook to the car and retrieve trouble codes with...They don't charge you to check them....

Good afternoon,

My cruise control green light will illuminate for about 1 second and then go off. I have replaced the multifunction switch, the two brake switches appear to open and close, however, I haven’t checked continuity with a meter thus far. The vacuum is strong and the servo diaphragm seems to flex well.

Interestingly, once I have pressed the set switch, I have to turn the car off and restart it in order to get the cruise to come on for another second.

Any ideas,

Thanks

Did you happen to check the relay for the cruise control? And also the brake switch?

Who was that masked man? You nailed it- the brake switch was the problem. I shorted terminal C and D to bypass the switch, definitively diagnosing the faulty part.

It was surprising to learn that that the cruise light would briefly illuminate even though the break switch was inoperative.

It appears the old switch will only come out in pieces, hopefully the new switch includes the snap in plastic that attaches the unit to the metal bracket.

Thanks for your help,

You are most welcome. Just let us know if we can be of any help in the future.

I have just replaced the cruise control servo and the brake switch on my 1995 Buick Park Avenue. I, however, am still having problems with it kicking out and not resuming. If I help it with the gas pedal, sometimes it will pick it back up for a few seconds before it kicks out again. The cruise light stays on the whole time. After replacing the above parts, what am I still missing? Thanks! Brent

Get scan done to see if there are any trouble codes. Cruise control system is controlled by the PCM.

at 65 mph, cruise control shut off and would not come back on. Mechanic checked all switches, replaced ECM, checked continuity in all wiring. Mechanic stated that the ECM was not sending a signal to the Servo.

Hi jimmie d horton,

Thank you for the donation.

Is there any trouble codes set in the PCM?

Thank you, KHLow2008. for your response. My mechanic said there were no trouble codes.

If all items are checked to be functioning correctly, then the PCM has to be substituted to test if that is the cause as it is part of the cruise control system. Any missing signal from the PCM would cause the cruise control to stop working.

One of the thing to test would be to get the freeze frame data to understand the situation when it occurs. That might show if any item malfunctioned without causing any trouble codes to be recorded when the cruise control failed.

The cruise control will not come on. Is there a fuse for this?

You are welcomed.
