Possible Failed PCM
Possible Failed PCM
I'm new to this forum. Hope there is someone who can help!
My '95 Formula lost A/C and a couple of months later the coolant fans stopped working. Right now I'm running with the fans jumpered to ground at the relays. A/C system seems to have enough pressure. Checked wiring from PCM to the relays, engine temp sensor and A/C pressure sensor. Temp and pressure sensors appear good. All good. Seems like all that's left is the PCM. Any ideas? TIA
