So I am out in the mountains of Colorado on an elk hunt and my heater stops working. I narrow the problem down to the switch and say I will fix it when I get back home.
Here is what I find when I pull the dash off later.
It completely melted the plastic connector and wires. Fried the back of the dash panel as well.
Any suggestions? Any ideas how this happened?
Update:
I spent a couple more hours researching this and found
this thread at jeepforum.com
It seems Chrysler used wire too small to handle the load when the motor starts to wear out and increase the amp draw. A lack of relays in the circuit further compunds the issue and has led to vehicle fires. Way to go, Chrysler.
It explains everything. Thanks for the help guys, I am going to rewire the entire thing with larger wire.
