I have had this problem 3 times with my vehicle now. The vehicle was having heater problems on highest and second highest speeds. Took the Jeep to the dealership and paid deductable on the service contract in October 2002. Dealer replaced the under dash harness, blower motor and the blower motor resistor. I continued to have problems and took it to my personal mechanic that discovered that the heater control module had failled as well. He replaced the heater control module and Jeep worked fine for 1 year. The heater began to have the same problems again and my personal mechanic replaced the blower motor, blower motor resistor and the heater control unit as well as replacing a burnt wire. The heater again lasted just over a year before actually catching fire under the dash. The entire under dash harness, blower motor, blower motor resistor and heater control unit were again replaced. No additional problems within the past week after receiving the Jeep from the shop.
