Replying to: jacean (Mar 10, 2008 4:22 pm) I'm also having problems with the seat warmers and the heater not working, I'm taking mine to the dealership tomorrow and see what they have to say about it.

Replying to: belloli (Feb 19, 2008 6:07 pm) So, for good measure out there, can anyone tell me if replacing their Body Control Module has resolved their electrical problems with their Azteks? I'd like to hear the feedback on this front before I spend another couple of hundred dollars chasing this.   Thanks, all...

Replying to: belloli (Mar 18, 2008 6:09 pm) I had the BCM replaced on mine last week, and it has been working fine since then. Before being replaced, I was having all kinds of problems with my 01' Tek. Had gotten to the point that even when parked and engine shut off, there were still clicking noises going on (door locks, lift gate, lights not going off). The horn even started going off one evening. I hope the BCM doesn't go out again anytime soon. Good Luck!
#167 of 366 BCM by vaaztek Mar 19, 2008 (8:26 am)
I've spent about $260 to a mechanic who discovered some bare wires to the BCM and re-insulated them in the belief that this would fix my problems. (I too have the "disco effect" and the door locks cycle and the hatch opened without warning a few weeks ago.)   Still having similar problems, I suspect that the BCM is the next thing to replace. Anyone have suggestions for a source for a new, inexpensive BCM?
#168 of 366 BCM, gauges go crazy on cranking by pemberton94 Mar 23, 2008 (11:27 pm)
I've been reading on this forum about problems with the BCM, and I suspect that my 2001 Aztek has a similar problem, but with perhaps a slight difference: My problem happens ONLY when the car is warm--like after it's been running for a while (more than 10 or 20 minutes) or if it has been parked in the sun. Also, nothing ever seems to go wrong WHILE driving, even for extended times. The problem only occurs when I shut it off and then RE-crank it. Occasionally, on these occasions, the problems go for a while, and then the car settles into stasis and everything works as it should, while at other times, I get the "Service Vehicle Soon / Security" light, and sometimes even get systems to lock (like the radio and window controls).   Has anyone else noticed this particular sequence of events? That is, nothing goes wrong except when the car is cranked when warm?   I'm thinking about ordering a BCM online, since my local Autozone couldn't locate it in their catalog. Any advice? Thanks for any help.

Replying to: belloli (Mar 18, 2008 6:09 pm) Well, it worked for me. Just replaced the BCM and everything has been working properly since then.
#170 of 366 2002 Aztek problems by audiofenix Mar 26, 2008 (11:03 am)
Ever since we bought the Aztek 2 years ago now I've suspected it of having some electrical problems. At first it was just the radio switching sources (say going from FM to CD player, or changing stations) from the time we turned it off to the next time we started it up. The radio would also be up ALL the way after starting it up sometimes.   Then we had our first oil change and the people could not figure out how to turn off the "change engine oil" indicator. It still goes away off and on to this day.   Next the rear hatch would not open completely with one press of the button (mostly when it is colder out) and one of us would have to be pulling up on it when we pressed the button again for it to open.   Now, oh boy, now we have all sorts of problems. The AC is currently out. We're having a local mechanic look at it and they think that is just due in part to a leak in one of the hoses. They put some free-on in and it worked great again for a day, but now it's back to just blowing air. They put a dye into the system so hopefully they will be able to find a leak for that.   Aside from that, the check engine light will randomly come on every once in a while for no reason. Recently my fiancee had told me that the temperature gauge had been spiking up and getting the warning on the display. After turning the car off and coming back, it's back to normal.   I've read a few things to try, like the method to turn off the oil light and a round about way to get rid of the strange happenings by detaching the battery for a while. I keep seeing BCM though. I'm not familiar with what this is so if anyone could give me any additional advice as to what to do for my issues, and/or explain to me what the BCM is and what it does, I would be greatful. Thanks in advance. Replies to this message: ray80 (Mar 27, 2008 6:56 am)

Replying to: audiofenix (Mar 26, 2008 11:03 am) For the AC, if the condensor has never been changed to updated part, it is likely that may be the culprit (cracked). For the temp gauge, if the collant level is proper (both overflow tank and radiater) it may be problem with sticky thermostat and could also cause SES light (and may cause more serious problems if it really overheats). The Body Control Module has its hands in many electrical functions (not engine related), things like instrument panel radio lights and others.
#172 of 366 problems with bcm by speck66 Mar 27, 2008 (8:13 am)
My 01 tek has had similar problems to what I have been reading. It was like it was haunted. Lights came on after turning off ignition key. Horn sounding with no one in the car. Doors unlocking by themselves, especially the driver side. The latest was a starting problem. It would start sometimes, and sometimes not. I would get out, open the hood, giggle some wires like the ones going to the starter. Maybe it would start, maybe not. I got another car and jumped the battery. Sometimes it would start, sometimes not. It wasn't until I moved the negative battery cable that it would start more consistantly. I narrowed it down to the ground wire going from the negative battery terminal to the car body. I jumpered it with a wire and it started. What I ended up doing was taking the wire loose and running a jumper wire from the negative battery terminal to the car body. It works fine now for the starting problem. thinking my problems with the bcm were over, I tried using the keyless entry fob. Mistake. Back to the haunted effect. I reprogrammed the bcm to use only the key to open the doors and everything works the way it should.
