this is my first forum. I have a 96 cherokee and my ignition block keeps buring up. I go thru one about once a year. Usually, my radio goes then my a/c, and then the ignition.

When I am using the vent or a/c, then ignition block gets very hot and smells bad. It usually does this quicker if I have my fan on hi. Currently, my defrost doesn't work nor the heater. i have to move the switch back and forth numerous times to hopefully get it to work.

I'm wondering if something is wrong with the climate control that is causing the ignition block to overheat. I hope that sombody can steer me towards the right solution.
