Report: AC Blower May Only Work on High or Melt Connector at Blower
Jeep Grand Cherokee Problem
Model Years Affected: 1993, 1999, 2000, 2001, 2002, 2003, 2004
Average Mileage: 98,875 mi (48,000 mi - 127,000 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 heater had developed a short where the wire under the passenger seat attaches to the heater blower unit. The heat will only work sometimes. Upon removal of the connection, it is noticed that the black plastic housing has melted. This same problem happened on the 1999 model jeep. This was repaired.

A/C unit cuts out on hot days after 45 minutes of operation and will not come back on until the car has cooled down. I believe it a short in the blower motor.

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

I just purchased this vechicle used, and the first thing to go wrong was the bender doors. i brought back to the dealer and made them repair. Now my heater works on occassion. I discovered that the wire is loose at the resistor. I have not made the repair yet. I am going to try replacing the wire and connector first. I do not want to spend more than this truck is worth!!!
I'm going back to Chevys!!!
