85 chevy c10 2wd A/C heater blower fan relay
« on: November 18, 2012, 03:46:24 PM »
I am looking for the electrical circut diagram for the blower motor fan from cabin switch to relay to fuse box. I have replaced the 4 speed fan switch and 5 pin relay with the recommended new parts checked 25amp a/c heater fuse and still no power to fan motor. I manually close relay and fan runs. I looked for obvious wire damage and see none , all plugins look good to. All the wiring is original and the colors on them are still bright enough to see good. The relay I replaced was 14036273 the new replacement they gave me was a murray 35777.  Thanks for any knowledge in advance
