Topic: Crazy Heater Blower

[Bluemoon]

Went to Big Rock Maysville, KY for a trail ride with club a couple weeks ago. And ever since then my heater controls are all wacked. The blower stays on high even tho the controls are turned low or off. I have replaced the resistor under the glove box but that didnt help.    Guess my next step is to replace the control panel or blower. I couldnt take it anymore so i pulled the blower fuse out, was to annoying... Of course now i have no flippn heat at all and the temp outside is dropping fast here in OH.

My heater/AC controls were screwed up.  I had max heat (or max cool) only.  The problem was in the temp control. 
I tore the panel apart.
The three controls had all gotten extremely hot at some point.  There was some plastic melting.
I suspect the previous owner had run the heat on high for a long period of time.  Maybe to clear the windows?
I cleaned everything up, replaced the one control (less than 20 bucks) then reassembled.
Everything works fine now.

The way my TJ heats it would SUCK if it was on all the time!  My wife would rather drive the Jeep when its cold out because by the time you three houses down that sucker is hot!!!
