AC and Heater Relay???

[mxmusik_12]

Which relay is located behind the dash for AC and heater to control climate controller? My AC and Heater is not working! Need relay. I have everything assemble but missing a relay which is behind my CD player? I need suggestion.

I believe the relay for your a/c is in your engine bay and not behind the dash. Have you checked inside the fuse box (located just behind the battery)?

Missing a module behind the dash for controlling Climate controll???? Help or suggestion. I look check the engine bay for the AC relay but it not that.

Two possible ways to determine the problem quickly/efficiently would be to either find another Mkiv Supra owner in your area that is willing to let you take his/her dash apart so you can compare yours to his/hers ... OR ... get a set of TSRMs for your Supra so that you can compare the step-by-step instructions of the dash disassembly to what you find in your Supra.

Unfortunately, it'll probably be very difficult for anyone to determine exactly what you're missing from reading a few typewritten words. Could post some pictures?

Here are a couple of behind-the-dash pictures for your reference:



Again, if you could post some of your own pictures that would probably help to figure out what you're missing...

Actually it's not my deck, nor is it a picture of my Supra. Either way I think it may be the abs ecu (or possibly traction control related), but I'm not 100% sure. I know you could find out exactly what it is in your TSRM. Also, next time I'm inside my dash, I'll be sure to check for any label/printing on that device and post it in this thread.

Fwiw, I can say I'm about 98%+ confident that white box has nothing whatsoever to do with your heater or your a/c...
