  • Hey turns out I was pretty close to being right!! He agrees it's definitely something with the electrical...prob. a circuit fuse, although he wasnt too helpful with a solution. I know there is a fuse box inside the glove compartment...maybe if you fiddle with the one that corresponds to the heat and blower panal??
    Mentioned your problem to my Father in law who is a retired part rep. for GM and he was convinced it was a "blower regulator" i believe thats what he said. but that's just based on a common replacement part in grand prix.
    well, now that i've confused you royally, i hope this helps ;) !!!
  • I have a 95 grand prix and for some reason my brake light won't work,I have no manual so I can't look anything up. HELP PLEASE!!! :confuse:
  • My battery charger says the alternator is out on the wife's 2001, I've changed a few in my day (never on this car, it's been perfect!) but here's the problem...
    everything was unhooked leaving the lower "pivot" bolt loose, I then realized it has a spring holding tension on the alternator. If I pull the final bolt, how do you "set" the spring to replace the alternator. Any help or links to information or repair sights would be a huge help.
  • Lights in both radio control buttons on the steering wheel have gone out on my 1998 Pontiac GP. I tried to pry off the buttons or pull the assembly out of the wheel but no luck. I was afraid to force it and risk damage. There is nothing in the owners manual about replacing these bulbs.
    Does anyone know how to replace them or if they can even be replaced?
  • Under you dashboard about 10” above your parking brake paddle is a diode. It about 3” X 1.5” X 1.5”, rectangular shape and it has cooling fins. Just unplug it.
  • HAVE YOU FIX THE PROBLEM.

    IDEA TRYING GETTING THE IGNITION SWITCH WIRES REPLACE ABOUT 100.00 BUT THEY CONTROL ALL WHAT YOUR SAYING IT WORKED FOR ME.
  • :lemon: :sick: For the past few months i have trouble starting the engine. I brought the car to the car dealership and they replaced the fuel flow regulator. The car still didnt start properly. It actually got worse and stalled out on me a few times while i was driving to work... WHAT IS GOING ON??? Again i brought it to the dealer ship and they said it could be the fuse box... that is a bunch of BS!! I finally brought it another pontiac dealership and they diagnost the problem as a computer glitch... there is no way im going to spend that much money... IM DONE WITH GM FOR GOOD!!!!

    I went to turn on my wipers, and the driver side first started wiping over past the windshield and running into my
    rearview mirror, then stopped working altogether. The passenger's side works. It's a 2007 and it shouldn't have problems yet. Did I kill it?

    The only break light I have working in my 2000 Grand Prix GTP is the center one. I tried to replace the bulbs in yesterda but it still didn't work, so I guessing it must be an electrical issue with the wiring (the other tail lights and blikers work fine).

    I'm not much of a car guy - is there any chance this is something I can repair myself, and assuming it's going to take a trip to the dealership does anyone have an guess as to what it might cost?

    I have an 02 Grand Prix with the same identical problem. I too would like some info on this.

    I had a problem with my car leaking water in through the cowling above the AC/Heat blower motor. I have fixed the leak and replaced the blower motor.

    When the leak was present my door locks would lock and unlock while I was driving and sometimes they wouldn't lock when you put the car in gear, and they would not unlock when you shut the car off.

    Now they don't lock while I'm driving, but they also don't lock when you put the car in gear and if I lock them they don't unlock when I shut the car off. Is there a specific fuse that might have corrosion on it or something like that? I can't find a fuse for just power locks. There are fuses for security, pass III and so on...

    In The back of the manual(haynes), the last schmatic shows a box (for)daylight running lights, and the same thing with the box gone for no dlr;s.Got me where the boxs is but it needs to be removed and wires put back together.

    I am trying to locate the relay for the secondary air injection system, any help would be great. thanx
  • I have an '03 GT & the drivers heated seat continued to heat after the switch was shut off. The next morning I had a dead battery. I took the fuse out. Any ideas on what's wrong?
  • Did you ever get this working? What did you have to do? I'm having the exact same problem. Thanks.
  • My windshield wipers on my 98 gtp work fine when turned on, but when they are turned of they go staight up to the verticle position and stay there. Any ideas?
  • I had the exact same problem for two days on my 2002 Grand Prix V6 3.8L last year, with only the center brake light working. I looked at the wiring, etc. but could not find the problem. Just as suddenly the problem went away for about one year but I never knew why the two brake lights worked once again.

    Last week the same brake light problem reappeared with center light OK and turn signals working but the two main brake lights would NOT work when I pressed down on the brake pedal. The two brake light bulbs did light up when I used a remote function like locking or unlocking the car or opening the trunk. I then searched most of the web and found one person who suggested a solution that he said sounded silly but that worked for him. I tried the solution and it also worked for me.

    Seems the problem has to do with the hazard and signal switch and some kind of short. I noted many more messages on the web describing the same problem, some with even more symptoms.

    Solution: My hazard signal switch was stuck in the down or off position. I carefully jiggled the switch with light upward pressure. The hazard switch button broke free after a few seconds and the 4 way flashers engaged and worked without problem. I then clicked the hazard switch on and off about three or four times. Now my brake lights work fine. It has been 5 days and the brake lights are still working without problem. Try this simple solution and see if that solves your problem. It saved me a lot of money at the dealer. My internet research says total cost to fix this problem at the dealer is about $600 ($350 labor and $250 parts). The part is a multi function or combination switch and includes turn signals, hazard, cruise control, etc. Hope this helps a little.

    I have a 2001 Pontiac Grand Prix...150,000 miles.

    Randomly, but typically when the engine is first started, the ac/heat/fan/rear defogger and the headlights won't turn on. (The car has a built in sensor for the headlights to turn on automatically at dark. If I turn the light on manually, they work fine.)
    The other evening, I was driving and the headlights randomly shut off (this was a first) - but again, when I turned the nob, they turned on.
    I have had it to the dealers twice now and they have checked the connectors and can't find anything wrong.

    Other random (electrical?) items - the passenger side stereo speaker will stop working and then work again....the "mute" button on the steering wheel when pressed, will mute the radio only for a second and then the radio starts playing again....the LCD display on the car stereo system works most of the time, but randomly won't at others.

    There doesn't seem to be a common thread to any of this, day/night, heat/cold, wet/dry/humid/snow.....does anyone have any ideas on what could be going wrong and what can be done to fix it? I can live without a lot of things but the defrosters in the winter aren't one of them.....please help...thanks!
