Model Years Affected: 1993, 1997, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006

Average Mileage: 111,614 mi (48,000 mi - 160,000 mi)


Failure in the blower motor power module (automatic temperature controls) or resistor block (manual AC) may cause the heater blower motor to work only on the high setting. The connector to the power module/resistor block is known to overheat (and sometimes melt). The connector or terminals should be replaced; a replacement connector is available.

    My experience with the ac blower connector melting is one of the flaws in that year of jeep. I simply cut that connector out and put a connector from Dorman® Tech Choice™ - Blower Motor Resistor Connector Part # 973-304 $9.99 can be purchased from Orielly auto parts or online at Replaced that connector and I have (NOT)had that problem again. One of many poor designs flaws from Chrysler.

    I just needed another connector installed and made the mistake of taking my 2000 jeep to Suncost Chysler in St. petersburg FL. After they were done with my car it cost over $1800.00 as they broke my vent doors after replacing not only the connector but the resistor. It now required removal of the dash to fix vent doors. All these systems worked fine when brought into Suncost. After they removed the dash they claimed the condenser was leaking freon. This car could freeze your legs before they got ahold of it.

    Wires at the heater blower resister burnt and melted the resister. Had to replace wiring and resister

    Blower controls would randomly turn on / off. Wire was melted near the resistor. Replacement took place on 02/2011 and cost $190.00

    Same exact problem, the controls for mid settings dont work and I can only get air on high and low settings

    AC blower only works on high, not fixed yet, that's why I'm here to find the fix.

    intermittent connection on rear park/tail lights.I adjusted the contacts in the lamp sockets. Tail lights stay on now but blowing fuses when I apply brakes.
