Hello,
I have a 95 chevy cavalier with the 2.2. I have 3 relays non functional. the Electric fan, ABS and heater blower motor. I tried repalcing the relays which did not work. I did however run a jumper wire on each circiut and I get power to the electric fan, ABS and heater blower motor by doin this. Also the 3 relays are located next to one another. Do I have a bad circiut borad? not sure whats causing the problem..

Suspect ground fault but all three are ground by different circuits. Did all go out at once? recent repair? have you pull relay center off and checked wiring?

yes they all went out at once. yeah The problem started when I jumped the electric fan circuit. after I determined I had power to the fan by running the jump wire. I got in the car, started it and the ABS and red brake light were on. also noticed the heater fan stopped working. no have not checked wiring on relay center yet.

May have powered up PCM ground and that could cause all kinds of problems
