Dylan86GL10 Posted December 21, 2009 Share Posted December 21, 2009 Does anyone have an EA82 wiring diagram for the a/c-heat controls (at the dash)? I've searched every wiring diagram I have and don't see anything more than the blower relay wiring covered. Thanks! Quote Link to comment Share on other sites More sharing options...
hisubaru Posted December 21, 2009 Share Posted December 21, 2009 Does the diagram at the bottom of this page help? http://www.indysworld.com/80s/general/USRM/mick-usrm/resistor-pack/resistorpack.html Quote Link to comment Share on other sites More sharing options...
Dylan86GL10 Posted December 22, 2009 Author Share Posted December 22, 2009 Thanks! I do have that one, I'm looking for anything that shows the wiring that runs from the HVAC controls (heat, bilevel, defrost, ac, ac max over the fan speed and wiper switch) I haven't ever seen this set of switches covered on any diagrams.

eulogious Posted December 23, 2009 Share Posted December 23, 2009 There isn't any "wiring" there, it's controlled by vacuum. If you are wondering how the A/C is turned on, there is a microswitch that controls this. It's located down in the gas pedal areaish. Other than that, there isn't a diagram for it since it's controlled by vacuum. What exactly are you looking to do with the diagram? Quote Link to comment Share on other sites More sharing options...

Probably the six wire harness that comes from the back of the switches I'll post a pic tonight. Quote Link to comment Share on other sites More sharing options...
eulogious Posted December 23, 2009 Share Posted December 23, 2009 You still haven't told me what you want to do with them... From what I can tell those wires are for the lights behind the switches, at least that's all I can see they do. They don't control anything within the ventilation system that I can tell. I know they don't control the AC or the fresh air controls. I have studied the FSM diagrams intensely for another project, yes I have them, and there is nothing there at all for these wires, hence why I asked what you were trying to accomplish. After reading the FSM for a long time and running down wires over several pages looking for these specific wires, I gave up since it was apparent they weren't important. I have also been to the pull a part by my house and took the dash apart on an ea82 to follow the wires and I couldn't tell where they went or go to, so I realize there are wires there, but they really don't do anything having to do with the ventilation that I can tell. Everything is controlled by vacuum or a microswitch. If I knew what your end goal was, I might be able to help, but AFAIK those wires don't really do anything important and aren't listed in the FSM that I have. Somebody correct me if I am wrong on this... Quote Link to comment Share on other sites More sharing options...
