#86 of 115 My 2002 Pontiac Bonneville by san77 May 08, 2009 (8:22 am)
The new problem is the front windows, they will not work, they are stuck on up position. The heater/air motor is also going out, so there is not air, no way to get windows down. The back windows back in the winter one at a time, fell, and could not go back up, so they are bolted UP. The Sun roof is broken. I just got a call from our auto mechanic and they said to pick the car up they could not figure the problem out. I know the radio as well used to shut off when the door opens, well it stays on till it desides to shut off. I am going to have to take this to an electical specialist,,,, that is going to be very expensive..I think the car has been a lemon from the start, all the extra's on this car is not working...Windows, Heated seats, sun roof, heater/ air fan motor, But with the hot days coming, the car is black with leather seats, no air to circulate gets really hot,,,,, Can any one help,,, we checked the fuses,,,,, Replies to this message: imidazol97 (May 08, 2009 9:08 am) imidazol97 (May 18, 2009 6:52 am)

Replying to: san77 (May 08, 2009 8:22 am) The blower motor most likely is a poor ground from the motor that barely makes contact. If you can take the motor apart it's at the brushes end. Some people extend it with a copper braid wire. If you kick you foot up against the bottom of the heater case in the middle, does it start working? Or when you hit a bump?   The windows are controlled by various modules that talk to each other over the network. Do your door locks work? There's a main module in the driver's door that communicates with the other door modules. Some people find a poor connection in a braid of several wires running under the carpet under the middle of the driver's seat area. There's a connection which may corrode.   There also are several different fuses involved including under the rear seat and under the hood. The radio going off is part of the retained power and someone elsewhere just went through a diagnosis with it. I do not know if it's a part of your problem. I have not diagnosed one of these, but have read several people having done so.   Your rear window is the regulator which has a slide that moves up and down via a metal cable to move the glass. The metal cable terminates in a plastic part. The supplier gave them several which are defective and break that went into 2000-2002s the way it sounds. People take out their regulator and send them to places on Ebay or other sources which repair and return or do an exchange. I do not recommend Ebay, but sometimes they have what is needed.   If you set up your carspace email on your carspace page in the upper corner of this page which say's "my carspace" then send me an email at my carspace account which is my username in the title for this post with an at sign and carspace dot com. I'll try to help you find info.
#88 of 115 Installing a 3.8SC in my 2002 Bonneville by 02gtpbonn May 18, 2009 (4:42 am)
Hi everyone. I am a longtime lurker to this great forum and I need your help.  I just put a 2001 3.8 SC from A Grand Prix GTP in my 02 Bonneville. The motor is in and all that is left is the electrical and the front shaft connections.  I have a few questions and need some help if possible!    1. We are thinking we need to use the computer for the GTP motor.  2. The wiring harness( where it plugs into the fuse box, and the connection in the firewall-under the master cylinder is different.) The 02 takes a rectangular plug, and the one on the new motor is round.    Anyone have any ideas on how to proceed?   Thanks Joe

Replying to: san77 (May 08, 2009 8:22 am) I found your email, finally. Check your mailbox. Pay special attention to the link about the connection under the front seat that can stay wet and is a junction between the modules in the doors. People have found that doesn't make contact causing things to not work because they can't talk to themodule in the driver's door.   Good luck.

Replying to: awu10 (Nov 13, 2006 1:08 pm) I'm experiencing the same issue with locks going on and off while driving. Have you heard any reason why?
#91 of 115 security system by tjacks1 Jun 01, 2009 (5:26 pm)
i cant get car to turn over when i try to jump starer with screwdriver it turns over but wont do it with th key is there a way to disable the security system or reset it the keys have a chip on it and i was told it might not be reconizeing them any one out there who can help with this problem Replies to this message: imidazol97 (Jun 02, 2009 6:52 am)
#92 of 115 Re: security system [tjacks1] by imidazol97 Jun 02, 2009 (6:52 am)
Replying to: tjacks1 (Jun 01, 2009 5:26 pm) This is an early solution. http://vats.likeabigdog.com/t   If you put your key in and turn it to on and the security light flashes for 3 minutes and then resets to read a new key insertion, you either have broken wires in the column where the tilt flexes, the contacts that rub the chip are dirty (alcohol on key when inserted may help), or the contacts on the key are dirty (rub with pencil eraser).   When the system doesn't read the chip right, the lights on dash all come on, but when turned to start nothing happens. You'll hear fuel pump when key is turned to on. But injectors and starter are disabled for 3 minutes after you turn the key 3 times to start with a wrong resistance reading.   You can read your resistor with a meter, and match with the 15 choices in the link I posted. Buy resistors at radio shack for a series you solder together. Or see an aftermarket alarm place; they routined bypass these with resistor sets for alarms they install.
#93 of 115 Re: Light out in stereo on '04 Bonneville [josiah624] by rednuf Jun 04, 2009 (6:36 am)
Replying to: josiah624 (Jun 03, 2008 8:39 pm) Had same problem with my 02. Was told by dealer whole unit would need to be replaced. Then one day another light was out on my dash, so I slapped the top of the dash and that light came back on. So I decided to try it on my stereo. I flicked the display with my finger twice and the light came back on. You might try that. It's a shame that vehicles have become so complicated and so poorly made.
#94 of 115 94 SSEi odometer issues~Super confused?? by megaroos Jul 03, 2009 (2:58 pm)
My mom purchased her 94 from my brother last year. The car had issues with water leaking into the driver's side very close to the pedals. He assumed it was from the sunroof and taped it so it wouldn't leak and well you cannot use the sunroof anymore. That helped with the leaking, but it sat unused in a garage for a few years. The car however has been having issues with the dash. The odometer and the window that shows the little car icon (IDK what it's called) come on sporadically. The window flickers on and off but more so off lately. She cannot get the car inspected b/c of this issue. Before that, when the car would show up in the window, it would chime that the 3rd brake light was out(which is wasn't).   I am wondering where to even begin to look for the problem, is it a fuse or wire or both?? I'm thinking that the water had something to do with it.
#95 of 115 Ac blower motor by theelectrician Jul 09, 2009 (10:06 am)
I just changed out the a/c blower motor on my 2005 pontiac booneville. The motor will not come on. I found a field mouse lodged inside the old motor. Is there a fuse, relay or resistor that i need to check? The a/c compressor starts and stops with the switches on the dash. I have a newborn and gotta fix this fast.
