Question about 2003 Chevrolet Impala

1 Answer

Electrical Problem, I think

Ok so I have a 2003 Impala and haven't had any problems with it until now. I first noticed that my cruise control didn't work anymore, then shortly after that my A/C turns on only sometimes and it only works on speed 5. I cannot disable the A/C by pushing the button to use the heat. Also sometimes I have to turn the knob to defrost before it will turn on. Lately, if I leave my automatic lights on my radio and odometer lights start flickering and I can hear a clicking sound. If I pull the knob out to disable the automatic lights, it stops. What is going on? Help me please.

How to fix cruise control


Cruise controls can cease to engage if the clutch or brake light cruise switch are out of adjustment. If this happens, try placing you foot under the clutch pedal (if equipped) and lift up on it (toward you) and hold it while engaging the cruise. If it now works, it will likely cut out when you remove your foot from under the pedal. Check the brake pedal in an identical fashion. Adjusting the switch at the pedals can often solve he problem. Some vehicles (Honda, Acura, Ford, to name a few) have a plastic insert that mounts in the pedal arm which presses against the switch. These can become brittle and fracture into pieces. My Acura has little pieces of blue plastic on the floorboard around the brake pedal one afternoon and I noticed the cruise didn't work. It was the pieces of the insert that had come to pieces preventing the cruise from coming on. I replaced the insert and no more problem with the cruise.

Whenever I had my cruise control on, the engine would just quit. We stopped using cruise as we were on a trip. When we did a test run with the cruise on again, smoke and electrical smell started rolling...


It sounds like you have a serious electrical problem in your steering column. It is probably a bad switch for he cruise control or set of speed, but could also just be a bare wire touching the metal steering column.

The stalling COULD be that your cruise control is partially engaged.

01 audi tt quattro cruise controle stopped working


You own an Audi, everything is expensive. If your cruise light doesn't come on at all, you have an electrical problem. If the light comes on, you have an actuator problem, or a vacuum problem. The dealer, or a shop that works on Audi's should be able to find the problem.

I have a 2003 Ford Explorer and the cruise-control doesn't work any more. I had it for less than two years and the ****** won't cruz control again.


an easy answer would be a vacuum line with a hole but with this late model and the fact its a ford i would think electrical problem. ford likes to use relays in all its electrical apps. if not the switch itself maybe a relay. the problem is finding which one. i go down to the auto parts and see if i can find info on the relays i can see or take it to a shop u can trust and have it diagnosed
