I hate to ask, but after about 15 minutes with my heater on in my 53-3100, the switch gets hot enough to burn me. Well not the switch but the backside of it. Anyways I poked my head under the dash as best I could (im norwegian and my square head dont fit so good!) and it doesnt look like any wires are grounding out so I was wondering, is the wiring to small? Do I need to swap to a lower gauge? Or is this normal and I just use it sporadically? Just curious b4 I catch the dash on fire!

Thanks for your time-Jeff
