    having problems with select features controlled by the GCM unit. Not positive the GCM failed cause another one produces the same results. The power windows work by wiring around the relay, will wiring the interior lights around the relay work? I can expect that the stuff won't make things right, but at least the things will go up/down and light up.

    Sometimes the computer stuff has to be matched to the car's VIN or reflashed when you swap out modules. That typically requires a scan tool and sometimes a "dealer-only" scan tool.

    Oh, and I think the name of the module is GEM.

    Lots of stuff on the net about water leaks causing GEM problems.
