• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Engine stall while driving

    The car is a 2005 Pontiac Grand Prix with 3800 series 3 engine natural aspiration. I was driving on highway at about 65mph and the engine stalled (no response to gas pedal and engine rev fell. I don't think the rev on tachometer fell to 0 but I do not remember exactly.). I lost power steering...

    water leaks from the map light

    2005 Pontiac Grand Prix base model. No sunroof. Water leaks from the map light into the front cup holder. I saw a few thread that this is probably the Onstar Antenna since I don't have sun roof (I will test it later to confirm). From what I read in this forum, it seems loosen the antenna bolt...

    Replace rear brake pad and rotor on 2005 Grand Prix base

    I plan to replace the rear rotor and brake pads on a 2005 Grand Prix base model. I know that the piston has to be screwed in with a special tool that I can rent from AutoZone or Advanced Auto Parts. My question is whether I need to take out the parking brake cable? I have seen two videos on...

    Heat stake in blower motor resistor

    The blower motor resistor on my 2005 Grand Prix base model went bad. The fan stays at one speed and does not turn off after shutting off engine. The resistor is the original one as it is fixed there by the plastic rivet/heat stake. I looked online and it seems the service manual suggests that I...

    AC recirculation not working

    It is 2005 Pontiac Grand Prix base. The AC recirculation does not work. I remember when I press the recirculation button, the air from the vent seems to blow a little faster and there are more "noise". Now when I pressed the recirculation button, no change in sound and the outside air still...

    Crank but not start

    Yesterday morning, I tried to start the car but it just cranks without starting. Give it gas during that does not help. After trying it four times, it finally started. When it runs, everything is good. No rough running or any issue. Then it starts fine when I turn off the car and try to...

    Is it normal to have bubbles on the transmission dipstick?

    Thank you! It is definitely not that foamy. It looks like the picture I found on web. I usually have a little less bubbles than what the picture shows. Do you think this is acceptable?

    Is it normal to have bubbles on the transmission dipstick?

    When I checked the transmission fluid level today, I noticed that there were several small bubbles (probably 5-6 on one side) on the dipstick. The transmission fluid level is right at the full mark or maybe a tiny lower than the full mark (It is pretty hard to see accurately where the fluid...

    "oil" on transmission cooler line

    The rubber part of the transmission cooler line seems to be very oily (or maybe describe it as oil mixed with dirty cover the rubber part of the line). And I can see the oil dirt mixture on the plastic air dam under the line. But when I checked the transmission fluid level, the level is only a...

    How does radiator cap work?

    As I understand, the radiator cap has a spring so it can hold pressure. When the car heat up and the pressure exceed the pressure the spring can hold, the coolant will flow to the reservoir. When the car cools down, the fluid contract and create a vacuum. Then coolant can be sucked back...

    How difficult is it to replace front lower air deflector?

    It is the big piece of plastic air dam thing under the radiator. I saw a thread in "how to" section but it seems the post was lost. I have bump this plastic thing several times and there are several cracks on it. It seems it is just bunch of push-in retainers and bolts from my brief...

    Small air space in coolant reservoir

    I had a curious observation about coolant reservoir in my 05 grand prix base. I think the hose from the radiator filler neck to the reservoir should be airtight. So when the car heat up or cools down, coolant can be pushed out of sucked in to the radiator. It is strange to me why the coolant...

    Wiper chatter problem

    My wiper will chatter both on up and down stroke. It wipes very smoothly if there is no water or very litter water on the windshield. It will chatter when there is a lot of water (This is very confusing to me). I have tried everything I can think of but none of them totally solved problem...

    Clunk or grinding sound when shift into reverse

    First, the car drives great and shifting is very smooth. But, When I had a cold start and shift into reverse, I can hear a grinding kind or clunk sound. It does this when the car is cold. When the car is warm, the grinding goes away but I still hear kind of a clunk. The clunk is much weaker...
