I had disconnected the rear harness ground and forgot about it once.. when I pressed the brake funny things happened, the key buzzer came on, the gauges did weird things. I'm betting your problem is a ground somewhere.

You will burn that fan motor up if you have power to both the low and high speed circuits at the same time. Dump the low speed circuit altogether and use only the high speed side with the t-stat control.
