blower fan not working
2003 blazer blower fan not working ran fan from batt.and it works, fuses all good,have a relay on firewall,tested plug going in to relay,(5 pin) wires big orange has constant power, black has ground,blue, purple,small orange have nothing with ignition on ,small orange goes to #30 on the relay witch should have power thanks
stop all this wire analysis ok,it might not be a wiring fault;so take a plyer and nack the fan engine(i mean the fan back)if the fan pick that mean it the brush in the fan that is short but if it did not that mean it need checking.thanks
The resistor may be bad
guys could this be a bad temperate sensor?
