Default Replacing my Bcm

My bcm went out....
Should I:
A. Buy a used bcm and pcm from a same year Malibu as mines

or

B. Go to the dealer, buy a new bcm and have them program it to my malibu?

Depends on your budget? Going used might just work, buying and getting it programmed at the dealer specifically to your Bu will be pricey but will definitely get the job done.

The BCM will need to be programmed with the VIN. I'd take it in to a dealership or independent shop and get it replaced/programmed with a remanufactured BCM.

So does that mean the ones i pulled from some other 2001 Malibus are useless?

Once programmed, a BCM cannot be reprogrammed. I'm kind of curious how you came to the diagnostic that the "bcm went out" on your vehicle. Care to share the symptoms?

Am I supposed to be looking at darkened areas near the connector pins? If so, the source of the problem may be beyond the BCM. There are current-limiting resistors that protect the circuits in case pins are shorted to the ground. The usual way for widesperead burnt spots is when a >= 12V source is shorted to a 5V circuit. I wouldn't feel comfortable just throwing a new BCM at it. You need to take it in to a shop that can diagnose it properly.

i believe my problem came from me letting my brother try to fix my trunk release, he put a wire on the positive battery, and started poking around in the driver side kick panel making the trunk pop,

But anyway I just recieved a used Bcm in the Mail with the exact id number as mines 12206819 and everything works now door locks trunk release mirror lights ect......the only thing not coming on is the fuel pump, I did the 10 min learn thing the theft light turns off when I attempt to crank the malibu what could be the isssue now?

You can't expect to drop in a BCM that was VINed for another vehicle and expect it to be able to communicate with the ECM and TCM. If the seller led you to believe it'll work, he should've known better.

See im new to the Malibu game, I read sumwhere on United Malibus or this site really cant remember that as long as you get the same id number that they will work, well is there a way I can make my fuel pump come on til I save enough money for a new one then take it to the dealer?
