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.

Temperature Blend/Recirculation Doors May Fail and Cause AC Problems

Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.

2006 Jeep Grand Cherokee Recalls

The Engine May Turn Off Unexpectedly

While operating the vehicle the driver may hit the ignition key with their knee, accidentally moving the key out of the run position. If this were to occur the engine would turn off, affecting various safety systems and increasing the risk of a crash and/or personal injury. As of this writing, the remedy for this recall is still under development.

The Transfer Case may Shift into Neutral Unexpectedly

The 4-wheel drive transfer case can direct engine power to the rear wheels only, all four wheels, or in its neutral position, non at all. These vehicles are being recalled because the transfer case can shift into its neutral position without warning. If this were to occur, engine power would not reach any of the drive wheels and the vehicle could not move under its own power. Dealers will reprogram the final drive controller which governs the transfer case to correct this concern.

I've had my Cherokee for four years now and I've put on 123,000 miles. Just recently the front brake calipers siezed and had to be replaced. The air conditioning is acting up....apperently the door that controls the amount of outside air coming into the sytem has failed open. I have the same slow start issue others have noted. I've heard that this is caused by a sensor which will not allow ...
Love the ride, looks great, and good suspension. Exhaust manifold bolt broke, replaced manifold bolt & gasket- $365. Brakes pads and rotors turned @ 35k miles. Transmission-delayed engagement after extended shutdown. Had trans flushed & cooler flt replaced. Still does the same. 3.8L V-8 has good power. A/C works well. Overall, love it, but transmission scares me
