I have a 1996 Jeep Cherokee. The heater started making a funny noise so we bought a new blower motor. Then we bought a new resistor. We still could not get the speeds to work in the heater. So we then bought a switch. Well we come to find out that the switch harness was burnt to a crisp. I called the parts store and they don't carry them, so I then called a dealer. The dealer told me they don't just sell that harness I had to buy the entire one for everything in the Jeep. Then told me to go cut one out of a junk yard. I called my local junk yard and the guy went and cut three harnesses out. One that was a 1996, one that was a 1995, and both of the ends were burnt just like mine. He then cut one out of an even older one, and the wires were thicker than the ones on mine, and different colors. I tried hooking it up and it doesn't work. I believe that should be a recall and it should have to be replaced by the company. The company should also sell individual harnesses.
Fumes emitted when heater is turned on.
