SOURCE: 2002 Buick Rendezvous alternator removal

To get the alternator out, I had to move that large electical fuse / relay box out of the way,and remove washer bottle and battery. then use a 3/8" drive ratchet to move the tensioner forward to get the belt off. I used a small mirrow to get a view of the back bolts on the alternator and removed them.[ I used meteric # 15 open end & closed end combo wench. Keep turning the back bolts until the alternator become loose.]

SOURCE: Buick Rendezvous 2002 need codes?

the BCM needs to be programmed to operate the computer. a GM techII is now required to calibrate BCM to airbag, stereo, keyless entry, and control pcm data. This is required to make it all work. a gm service should have it done within an hour or less just call and ask them how much it would be to program new BCM. it might cost @$75 to $125 but it is needed, to allow the BCM to work properly.

Testimonial: "ok...i bought the bcm on line (used)...but the gays in the dealer says i have to buy a new one..because the used cannot be to reflashed...or recoded."

what you need to do is pull the radio out and write down the serial number then call the dealer for the code. they may charge you 15-25 bucks but that will save you some money

The fluid in the versa trak AWD in the rear is old and needs to be drained and refilled. After you drain and refill it, make a bunch of sharp left and right hand turns, then drive it for 10 minutes. Drain and refill it for the second time and problem solved. Use only versa trak fluid available at any GM dealership. Your vehicle takes 2 bottles (16.9 oz) each change. There is a TSB at the Buick dealership on this now.
