2008 Jeep Grand Cherokee ProblemsTemperature 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.
The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.
A no crank or no start condition may develop due to electronic lockup of the wireless control module (WCM), also referred to as the Sentry Key Remote Entry Module (SKREEM). When this module fails the remote keyless entry system will also not operate. The WCM is commonly replaced to correct this concern.

Every once in a while when I started my Jeep it would start ok, but I would have no power inside....no radio, windows, air, nothing! Now it won't start at all. Any ideas?
This sounds like playing card when put on a bicycle spoke. I've had different people say different things it could be, CV joint or drive shaft. I'm on a fixed income & can't afford to take it to a dealer. Any help I can get is appreciated.
2008 Jeep Grand Cherokee RecallsIgnition Key May Stick Between Positions in Ignition Key Cylinder
The ignition key may stick between desired positions in the ignition key cylinder mechanism, and may move between positions while driving. This can cause the engine to shut off and electrical accessories to stop operating. Dealers will repair this concern free of charge (a repair procedure is still under development as of the time of this writing).
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.
The front control module may have been manufactured incorrectly. As a result, the windshield wipers could fail or the engine could stall without warning, increasing the risk of a crash. Dealers will inspect the front control module and replace it as necessary. The recall is expected to begin on February 18, 2008. The Chrysler recall number is H03.
