Cruise Control to stop working?

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?

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

What r the code setting that I should be looking for and how do I find 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

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,

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

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.

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

Thanks again for your help. I will forward this info to my mechanic

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