91SHOmtx
New Member
hey guys, im new to the forum and im wondering if anybody here could help solve my problem. ive had my 91' SHO 3.0 for a little under a year now and ever since i bought it the cooling fan never kicked on and until today the temp gauge never worked. i put a new ect sensor, temp sensor, and ccrm (M code) in it this week. my temp gauge works great now, thank god, but my cooling fan still doesnt come on. even when i push max a/c the fan still fails to turn on. the car overall runs great and hasnt given me any other problems yet. now the confusing part, ive spent the better half of today trying to see why my fan doesnt kick on when its connected to the proper connections. it will run when wired to a switch thats wired to the battery, so my fan does work. ive printed off the different ccrm pin diagrams and it seems that my factory wiring harness that connects to my M code ccrm doesnt match any of the code diagrams. the pins that are missing from my harness dont match any of the un-used pins from any of the ccrm boxes. im mechanically inclined and prefer to not to send my vehicles to the shop. my question is does my car require a different ccrm box or is there another underlying problem of why my fan doesnt come on?
