Windows, Blower, Sunroof not working on 97 LT model
 

Hoping for some help on an issue that is driving me crazy. The following items are not working on my 97 LT model:

-Power windows
-Power sunroof
-Blower (A/C vent / heater blower)
-Also have an Anti-lock ABS light on

I am pretty sure it is all related because the problem started out intermittently. When 1 item worked, they all worked. When 1 was out, they all were out. Now they are all out for good.

After reading here, I am thinking it is probably a grounding / fuse issue. Maybe a BCM, but not sure.

Any advice on how to trouble shoot this? Thanks in advance!

P.S. Other items such as lights, locks, turn signals, power mirrors/seats, rear hatch, door chime, all work.
