Heater wiring diagram

[Babaganoosh]

It's that time of the year again, even though I live in Arizona I want it fixed. Does anybody happen to have a set for a 82? My switch is completely dead want to narrow it down before I throw a new switch at it.


Thanks
Ben

It gets cold in the desert at night! Mines not working either , the fan isnt anyway.I`d love to see a diagram too.

Check for 12V on the brown wire. That's the only wire that feeds power to the heater system. Comes off the fuse panel. There is a connector you can pop apart to test if you don't remove the connector from the heater head.

Thanks, I will have to try that tomorrow. Do you happen to have any more advice?

Well, you'll need to check for 12V on that wire, but you can also check for voltage on the plug to the motor. If AC there is a relay out on the AC housing, and whether AC or not there is a resistor cluster on the housing as well. You can check for voltage out there as well.

My suspicion would be the heater motor itself or power to that brown wire if you have nothing, as I recall, each wire to the motor gets power based on the switch setting, so unless there is something majorly wrong between the switch and the motor, the motor or brown power wire are the major likely culprits.

Thanks, if I get some time today to mess around I'll check it out.



Thank you.

Thank you.

brown wire to fuse panel. yellow wire from switch is low. lt blue from switch is med. orange wire is high. the heater wire is tied to the orange wire at the resistor on the side of the ac housing. this is from an 85 shop manual.

Awesome, thank you very much. Maybe tomorrow I can get some time if not Sunday I should be able to.
