hvac system not working

[rodebilder]

We have a J 30 we purchase new and it is a 93. Theater/air conditioning control is not working.I have purchased two used units on ebay, plugged them in and they work for a short time then go out. I am assuming it is my wiring harness to this control assembly. Has anyone else had this issue and how did you resolve it.Very much appreciated if someone would [email protected]

I'm assuming that when you mention theater/air conditioning control you are talking about the climate control system, correct?

Have you checked the adaptor for fraying wires, etc?

Yes and used a tester light and found only one hot terminal at the plug going into the climate control. Not having a wiring diagram I am not sure if there should be more than one hot wire going in.

I have checked all of the fuses both in the interior kickplate panel and under the hood.

Not sure what i should do next. any help would be very much appreciated.

Thanks
