crazy electrical issue! help!!!

[boston groomer]

just bout the 94 sho. it runs and drives great. but the coolant fant is stuck on. i have to disconnect the battery at night. also the heat and the subwoofer shut off when i put it in gear. i think its a short. anyone know where to start looking? also the winsheild wipers and sunroof dint work. i think the motors are probably bad, but maybe its all connected. hoping someone knows whats up. thanks!

Could be a short, or a voltage regulation issue. I'd check the alternator and CCRM first. Any recent work on the car or driving through high water etc?

I had the fan problem on my 92. Mice had chewed the wires on the IRCM/CCRm harness about 8 inches down from the plug. I would check the wiring first.

most likely cause in my experience is a sticking ccrm, but the wiring possibilities are legit as well.

you guys rock

thanks for the help. the car sat for two years. so mice chewing up a wire is probably the problem. its a good place to start looking anyway. how much does the ccrm cost? and wheres the best place to buy one? thank you!!

Look through the items for sale in this forum's classifieds, or go to RCM / SHO Source for their listing of available used CCRMs.

A wonderful thread that talks about the CCRM is here
