SOURCE: Heater works but defrost fills inside with fog.
your heater core has probably sprung a leak.does the fog smell kinda sweet?....check the floor in the front where the floor mats are for moisture or even puddles of antifreeze.(the replacement of a heater core can be very expensive as the entire dash usually needs to be removed to access the heater core)also look under the engine near the firewall for antifreeze drips.

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."
