I apologize in advance if this has been covered, but I have read other threads related but not found the answer I was looking for. Question number one is there a way to completely bypass the BCM on an 02 Aztek?  Question number 2, what could be burning through BCM's? I purchased the car knowing it was likely the problems (No AC, window controls, locked radio). Purchased a used BCM on ebay.. worked for 30 days or less... figured well maybe I just purchased a bad one. Purchased second used BCM locally, it worked fine for several months now, so I decided I would finally put the console back in lol.. connected the wire in the console for the power outlets, put it together and went to start the car. It acted like it didnt want to start, then an hour later would not start.. now it starts and runs fine just no window controls, ac, hatch access or head lights. I know I am using used BCMs, but one car and three BCM's? Oh and the vehicle has 76000 miles on it. Any advice would be appreciated.

In a word, no there is no real way to bypass a BCM.

I know there were problems with BCMs during the 02-03 model years. You did have the BCMs reflashed to your car, correct? I'm not well versed on BCMs but I do know they have to match the options and other features on your car.

Pretty sure that what BlueGT said is correct - the BCM has to be programmed/flashed (by the dealer) to your car. 

I wasn't aware that it was possible to use a used BCM because I didn't think they could be re-flashed.
