Heater Comes On When I Hit The Brakes
Got the weirdest problem i've ever seen. Got a 92 Buick Park Avenue. When I hit the brake pedal, the blower motor for the heater turns on. My brake lights work but are really dim. If I hit the brakes, the radio lights go out, the heater control panel lights go out. If I turn the headlights on, the car stalls and dies out. Even with the car turned off, if I hit the brake pedal, the heater motor will kick on. Cant find any wires that look shorted or damaged. Anybody got any ideas? By the way, the alternator puts out 14.8 volts, the battery is at 14.4 when running and 12.6 when car is off.

Re: Heater Comes On When I Hit The Brakes

Re: Heater Comes On When I Hit The Brakes
If you have a trailer wiring pigtail I'd start there. I've had some wierd feedback from shorts mine. My dome light would come on when I hit the brakes.
Good luck |

Re: Heater Comes On When I Hit The Brakes
No trailer pigtail. I still cant figure this out. Can't find a wire or wires that look the least bit bad. Can't find anything under the dash or the hood that catches my eye. Guess I might have to shop it. The car only has 70,000 original miles on it and is a good work car. That is if I can get it fixed. Thanx for the suggestions.

Check for water in the tail lights.
