I have a 2002 Pontiac Pontiac Bonneville SLE and it is the year and engine of the panic Mandeville that was recalled for the fuel issue and I was wondering if this car is also included on that recall as I am having the same issues as they described

Trying to fix air blowing on floor only. I have looked and do not see how to access the mode door actuator. To be honest I just want the air to blow out the cabin vents, so if I could just use a wrench or something to make that work I don't care about the other vents or actually replacing it, just making the vents in the cabin work. Thanks!

The amp gauge fluctuates from 9 amps to 14 amps and continues to go up and down without any regularity to it. Sometimes it happens constantly, and other times it's hours apart. I have replaced the alternator and battery both with brand new ones and it still made no difference. Two mechanics could not figure it out. What is the likely problem? Could it be bad batter connections or corrosion? Could it be a bad control module? It's getting very annoying, please help.

All the time

Cranks over like it wants to start but the more I hold the key the more the battery dies and it still won't start it started doing this 2 days ago I've had to hold the key longer to get it to start and now it still cranks but doesn't start just drains the battery more

Can the air compressor make the car not start?

Just changed axle and now the car doesn't move and grinds going in park

Car is not running hot at all idle is a little rough and sounds like I have like an air rumbling sound coming from my engine

one by one my power window's are failing. I replaced the driver side only. now the passenger window, which is not working keeps falling down as if nothing is holding it up and i would like to take the panel off to at least keep it up but i am concerned i wont be able to get it back on. any info is greatly needed.

My service engine light comes on and flashes rapidly, then the motor starts missing then motor quits , I put a diagnostic tester on it and it shows mutable sensor failure. did this ten times and it was never the same sensors showing up ,everything is random. I'm out of ideas .

problem as theres no sign of tranny problems. help, I need my car

I had a fuel fire letting a bum work on my vehicle.. I replaced everything the computer decoder said that was wrong from wiring harness to the alternator. My car is receiving power to everything but I am having a no crack no start in the ignition. A friebd of my got under my car with a screw driver an tapped at the starter or something an the car was turning over but would not stay running. Not sure what the problem is but really want to get this car fixed.I noticed the fuel lines are leaking alittle still If this could be a issue. Ease give me some kinda insite before I junk this car. It was in excellent running condition an I invested at least 2000 dollars into this vehicle getting it in the best running condition an it all fell apart because the person used a rubber line instead of the threaded line on the last 2 ft of fuel line from the the steel fuel line to the motor where the plastic sensor clips onto the top of the motor

VIN IG2HX52L4R4219511 i NEED A RADIATOR DON'TKNOW WHICH TO BUY ONE THAT COOLS ARE NOT

Replaced blend door actuator or same problem only reaches 100° Where is the temperature probe? It is a manual controls if I unplug actuator and turn vent door to hot temperature reaches 140°. Problem is when I turn the car off it goes back to halfway point and then won't drive to full heat?

Back brakes

Cables kept falling off while driving and I thought that causes alternator problems but replaced cables to reach for top post ? ( backwards) after that new battery then jump nothing but guys said starter smoked a little( starter was sticking before that) I'm now hum jumper cables reversed? Resistors in bypass to strong (bypassed cheap car without key) NOT STOLEN 98 Bonneville for Christ's sake. Now resistors redone by someone else he said wrong resistance but I'm thinking how when it Wouldn't have bypassed vats for new ignition in first place of it was but I read it can be a certain % below or above and still work? So of it was say 19% higher then actual resistance would that effect charging system drain battery and screw up either alternator starter relay solenoid maybe regulator (if there is one ) so no key to measure chip guy lost the resistors that started car in first place and. Says he's got new one hooked up but never shows to finish it and says he can start it but has to use something and never said what ( screwdriver to solenoid???) and hasn't been back where can i start please daughter needs car pregnant has three year old and can't make it to the Dr. And I'm out of resources as far as mechanic and you guys are so informative I'm going to do it myself. (can't afford no show mechanics anymore)

After bypass couldn't get lights to go off when starting and starter would stick. So I figured it would go out (starter) but a few things happened it died but cables weren't staying on the battery (side post) someone tried to alter it to make am stay on made it worse. After it died someone else put. Cables that would reach top post on (only had top post battery) not a real smart fellow anyway. But good guy tried because pregnet daughter with my three y old gradson stranded. Then no charge call me I go jump it and another concerned person helps out with connecting cables as I start it nothing and I m not sure but something alarmed me and got out he said a little smoke came from starter. So I thought jumpercables wrong or the actual terminal cables mixed up???? But then maybe resistors a little to high?? Cause lights not going out prior??? So now another person whom I've paid few times worked on it and said starter I thought well replace be good?? Nope he cut resistors out lost am man I'm not a genius but I had someone else measure and install them cause he couldn't now back to one again I'm kinda broke pissed and stuck. Cause what's resistance? How do I know even trying all fifteen cause the starter ?solenoid? Altenator? Relay? Resistors? And I don't know where to begin but I'm trying to do it myself cause I've had bad experience s (boyfriend tried to surprise me with oil change 2015 subaru and drained tranny fluid instead fifteen $ quart cvt hundreds $ later still fucked up and on and on. Please help. Where do I start again did mention no key right

Drive to store and car wouldn't start jumped start and smoke from startervand nothing not even crank

The vats system was by passed. And charging system was up down. To start the starter was sticking the battery wouldn't start car got a jump and smoke came from starter but the car never turned over like no power at all someone said solenoid but I was thinking the resisters were messes up ( from bypass vats)
