Re: Heater Fan- Reg heater vs AC Heater
Looking at the wiring diagram pictured earlier, it looks like the high current supply to the relay is under the dash. I colored the wire that I think is the correct one. Make sure you have 12 volts on that wire at the relay and 12 volts from the switch when set on high.
If the relay is working, and you have 12 volts from both those wires, you should have 12 volts on the purple that is headed out to the fan.
