WJ Blower Motor Controller AZC system

My 2004 Overland with AZC auto a/c system had original 5012699AA Blower Motor Controller/resistor had melted connector black ground wire terminal. My previous ground wire repair gave up in this current east coast heat wave with 98F/108 heat index.

I installed Alternate Blower Motor Resistor and Wiring Kit K6855672 from justforjeeps com 5179985AA which contains 5179985AA resistor (controller) and adapter plate/wiring 68052436AA. I understand this resistor/controller is from a post2004 Jeep

It is Alternative Blower Motor Resistor and Wiring Harness for '1999-2004 WJ Grand Cherokee models with Automatic Temperature Control (AZC) system only.

It can be used as an alternative to the original 5012699AA controller/resistor. However with this resistor the fan motor does not run as fast speed does not blow as much air as before.

Item # 5179985AA - Resistor
Item # 68052436AA - Wiring Harness.

I am going to repair original wiring to my controller with 51002406AA kit. I just ordered it from justforjeeps com/alblmore

Still trying to correct wiring kit p/n 5102406

5102406AA This is a common failure on 1999-2004 WJ models with the AZC (Automatic Zone Control) system. The connector on the blower motor control module overheats, resulting in intermittent or no operation of the blower motor. Mopar released a connector harness repair kit to fix the problem. The damaged connector is cut off and new wires are spliced into place. Only the green wires from the kit are used. One end of each of the 3 green wires goes into the new connector end that is provided. When inserting the wires into the connector, the locking spring tabs should be on the bottom. There is a gray plastic retainer that is then installed around the three wires that were just inserted into the connector.
The part number for the kit is 05102406AA. refer to wjjeeps com/blower_motor
