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

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.

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
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.
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 controls would randomly turn on / off. Wire was melted near the resistor. Replacement took place on 02/2011 and cost $190.00
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.
my blower freaked on high and then stopped working all together and it was smoking really bad and smelled like burnt rubber
First the AC would stop blowing out the dash vents when I accelerated redirecting the air to the defrost or floor vents. Dealership told me it was a redirection of power when I accelerated. Didn't sound right but I went with it. A few years later cruise control doesn't work, heater and AC both do not blow out the dash vents only defrost and sometimes floor vents. On top of that if it runs too long I start to smell a burning electrical smell. Thanks to this site I think I know what needs to be fixed with out spending a lot to have it looked at.
