Wiring? You should be checking the vacuum lines...

And the first google-machine result:

I've gone thru this a couple times with 84 & 85 with auto temp control. It was leaks in the vacuum system, either at the incoming line or, more common, a bad vacuum bellows on one or more of the control actuators. Unfortunately, the heater must be removed, a nasty job.
