AC Blower May Only Work on High or Melt Connector at Blower on Jeep Grand Cherokee

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.

2nd time this module melted.
ac/heat only blows out on high, there are no mid-level blow levels
Blower controls would randomly turn on / off. Wire was melted near the resistor. Replacement took place on 02/2011 and cost $190.00
Blower only works on High
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
I'm ordering the part from O'Reilly. I work at a tire store. My mechanic will replace it.
Motor works at high speed only.
the ac fan would only cool if the fan was on high. Now as of yesterday it has stopped blowing at all.
Ac/ heater only works on the high setting
Air condition and heat only works on the high setting
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 quit working. Found connector to fan motor melted.
The A/C blower motor only work on high speed. I got the resistor but I do not know where it is located so I can replace it.
replace fan relay switch 4 times it would work for a week or two then blow out
A/C Fan works only on high, when I start my car I hear a noise that comes from under the dashboard that last for a few seconds, the noise goes away but if I turn the a/c off or on the noise starts again for a few seconds, sometimes just by putting my keys on the ignition I hear that noise, I purchased this car brand new in 2005 and it was the worst car I ever owned in my life, I called Jeep and Chrysler ( NOT THE DEALERS) they didn't give a rat *ss about my problem, I like the Jeep Cherokee but with all the problems and the money I paid for this car, I will never buy a Chrysler/ Jeep ever again.
A/C and blower only work on the high setting. The blower resistor behind the glove compartment was removed and the electrical terminal has4 wires, the two outside wire connectors are burned. Replacement of the connector is next.
