Ok, lets start.
2002 Grand Prix SE, auto trans 3100 motor 120k miles
with keyless remotes
At first the blower motor had a bad vibration on any setting over 3. Then it quit all together. At about the same time the key would not come out of the ignition switch. replaced the ignition switch. after I replaced the switch the ding/ding thingy came on without the key in the ignition with the doors open. took it to dealer and asked them to reprogram it. they said they did but it still dings, fine I'll live with it, then the blower motor would run on 5 only with no AC or heat, checked refrigarent, its ok. replaced the switch panel in the console, same thing. took it to mechanic he replaced the blower motor resister. It worked good for about an hour. (still had the ding/ding when door open with no key in it, he said he didn't fix that) now, the blower and ac works only on 5 and only if you slide the pass/driv side temp control switches up and down. when you turn the fan switch on it turns off the daytime driving lights, but you can turn on the headlights and they work. Now, when you start the car the interior lights come on and stay on as long as the car is running. if you turn off the ignition switch the interior lights stay on for about 10min. then go off. I think its the body control module, but there are 3 diff modules on the driver side, a big rectangular one, with a smaller rectangular module beside it. the big rect. one had a sticker with a lot of numbers on it and says GRAY 04 REV D. and another one with a heat sink on it. any suggestions?
