Problem Description and Possible Solution
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.

Heat and AC only blow on HI setting.
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 Dorman.com.. Replaced that connector and I have (NOT)had that problem again. One of many poor designs flaws from Chrysler.
ac/heat only blows out on high, there are no mid-level blow levels
Blower only works on High
The blower would only work on high, then when turning on Ac I smelled something burning turned it off now the fan will not come on at all and won't even go to the high setting
2nd time this module melted.
A/c shuts off and I was able to get it to go back on by turning it off and on again bit the last few times I couldn't get it to come back on so I waited a couple days and I today turned the heat on and the heat came on and then it to shut off and then it can back on by itself and went back off again
Blower only works on high
A/C will come on and fan Wil blow only on highest speed. Not fixed yet.
AC blower only works on high setting.
Blower controls would randomly turn on / off. Wire was melted near the resistor. Replacement took place on 02/2011 and cost $190.00
Wires at the heater blower resister burnt and melted the resister. Had to replace wiring and resister
the ac fan would only cool if the fan was on high. Now as of yesterday it has stopped blowing at all.
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.
Same problem, heat and AC only work on high. Not fixed, looking for a solution.
Blower only works on high. It used to not work on low but now nothing works but high.
Heater blower only runs on high,
my blower freaked on high and then stopped working all together and it was smoking really bad and smelled like burnt rubber
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.
Fixed myself by buying an upgraded resister part from Advanced Auto. Removal and installation is moderately difficult due to one screw being a little difficult to reach. Note, you may have to rewire it because blower motor may operate in reverse. Look on Youtube to see solution on crossed wires.
