BCM - Electrical problem help...
I have a 98 T/a and for the past few months there is an electrical problem I can't pinpoint. Car starts easily battery is good alternator is good those were easy checks but at times when the car is running the radio is powered off and won't turn on and my power windows won't work. Or they roll half way down the die. If I wait about 10-15 seconds they work again. Front running lights work when they want to as well? Anyone ever have this occur??
It's the BCM, search that in general maintenance section and you'll find the fix. But what works for my trans am is when the radio and windows quit working here's what I do. If the drivers window is up or down just hold the switch in the opposite direction and lightly slap the dash above the center vents. That has worked for me at least once a week for 5-6 years now. When that quits working I'll have to fix it for real but it hasn't failed me yet.
Moved this OUT from the internal engine section TO the Firebird section.

The BCM needs some connectors soldered, i did this on mine. With a cheap solder gun you can knock this out in no time. Heres a youtube video i followed : https://m.youtube.com/watch?t=745s&v=VFTXuk3X94M
