© DenLorsTools.com Summary: Jeep Grand Cherokee’s with dual zone have a common problem of blend doors breaking at the point of actuator engagement. Vehicles affected are 1999, 2000, 2001, 2002, 2003 and 2004 Jeep Grand Cherokees. The automatic temperature control can be affected on the driver or passenger side, making the temp control inoperable. Until recently the refrigerant had to be discharged and the dash removed for repair. Now with a WJ blend door repair kit # K6855685AB, from Mopar/Chrysler/Fiat the repair can be done in the vehicle by even modestly experienced individuals. The kit includes an aluminum door door, a plastic door, a spindle, grease and patch material for resealing the evaporator case after repair.
