My BCM went out in my 2001 Pontiac Aztec a few years back and i had all kind of problems with it. My engine was idling really high as soon as i put it in park. My mileage stopped counting and most of the lights on my instrument panel were on if not all of them. The car still ran but if the BCM would have completely failed the car would not run. At least that is what the dealer told me. If your car is not under warranty be prepared to spend about 15 to 18 hundred to replace it.
Mine recently went out and it began with the instrument cluster lights flashing on and off, and the gauges going to "off" and then back on. The car performed fine, except for that. If it does totally fail, you will be stranded with a non-running car. I bought mine online (Amazon.com, rockauto, brightauto) for $168+shipping. If you're not afraid to do some work, you can remove all the trim around the BCM and take it to a trusted facility and see if they'll let you remove it and replace it, and then they'll just have to program it. Mine let me do this, and charged me $70 for programming. Total of $243, and about 2 hours worth of work. If you are able to do this, take your time removing the trim, there are some "hidden" screws...it can be fragile, I had to repair one piece of mine.

Try Ebay. I typed in Pontiac Aztek nd all kinds of parts and books for different years come up. Hope this helps
The Pontiac Aztek has a chain which will last the life of the engine and should never need replacing until the engine is overhauled.
