I took the BCM out of my car today and surprising there were no flaws in the factory solder joints on the circuit board! I checked all the wires attached to the three harnesses/plugs and all looked great as well. I plugged it back in the car and it hasn't done it since.

Just found this thread, I battled with the BCM for a while, but I cant get it out. I have not been able to get the side panel off, that one screw that is mentioned is too hard to get to. I need a very short phillips head. Does this side panel really have to come out, doesnt look like it when you look through the glovebox.
My doorlocks and interior lights stopped working today. I hear a click in the BCM. Must be a relay in there.
This thread looks promising. I'll be trying again tomorrow.

i've read every post in this topic......my door locks don't work......there is a clicking sound ,obviously a relay, coming from the area described.....this clicking repeats itself about every 10 seconds....the trunk latch works....when i use the key fob, i also get a clicking sound but the locks will not open or close....is this the bcm.......i tried a reset, didn't work...02 SS
the only fuse that stops this clicking is the 40 amp ignition fuse under the hood
someone here mentioned a fuse for their locks...i can find no fuse labeled for that system in the fuse boxes or in the manual

Does the BCM control the rear defroster and power seats? I still have not been able to determine why my R.Def only stays on for about 20secs then shuts off, and will not come back on for nothing for approx 5-10 mins. When it stops working, so do my power seats.

The seats and rear defroster are totally unrelated to the BCM and the fix described here. But they are both protected by the same 30 amp circuit breaker in the dash fuse panel. The circuit breaker doesn't work well when it gets old so it cuts out the circuit much too soon. You can replace it with another circuit breaker or just use a 30 amp fuse in the same spot.
I actually ended up resoldering mine again sometime in January. I didn't do it good enough the first time, and it was starting to cut off again. It's been fine all year..

Similar issue, but different Good morning,
I've read though many threads and I have a similar problem that I think is connected to the BCM. My trouble occurs when the car is off. Of course it's intermittant. After the car, '02 Camaro SS, is shut off and you leave, the radio, check engine light, security light, and seat belt light & chime turn on. If I open the door they shut off. ALSO, the fuel pump will prime for about 2-3 seconds. Car is off, in the garage, and key is in my hand. This will cycle every few minutes. Also I shut down the car one night and the dash lights stayed on, the gauges, bounced in time with the light chime, and this stayed on after the door was open and closed a few times. I disconnected the battery to stop the drain. Since then the bouncing gauges and dash lights have not appeared, but the Fuel pump and radio have turned on without notice. I know these are all on seperate curcuits and, from what I see, the common denominator is the BCM.
Thank you in advance.
