You will have to check the flap operating controls behind the centre consol as anything could be wrong from a vacumn pipe to a operating mechanism ,even the computer controlling the climatic control .

2002 Grand CHerokee: in cooling mode (summer), the


This is a chronic problem with Grand Cherokees. The blend doors inside the air box in the dash fail over time. This is caused by cheap plastic parts used by Chrysler that break easily.

Your problem is the forth Jeep I have seen like this in the past 2 months.

To check your climate control system for fault codes do this:

-Turn key to 'on'
-press and hold 'a/c' and 'recirc' buttons and turn drivers side temp knob clockwise one click.

Now the display will show 0 if no codes are present or one or more numbers if something is wrong.

You can check what these codes mean here: http://www.wjjeeps.com/climate.htm

you have to get a new control panel which cost usually around 800 dollars. Mine is the same way but i haven't got it fixed i just took out the glove box and kept the switch to tell the motor to make it hot or cold air and put a screw in it and have it held on hot for the winter then ill taker it out in the summer and have it blow cold air

Heating system


This is obviously a heater system control problem, I beleive this system is vaccuum controled with vacuum acuators that open and close doors in response to the climate control system comands.

Listen for the sound of escaping air from under the dash board, esp on the drivers side. Look for any unattached hoses under the dash. From there if you do not see anything obvious, you will have to obtain a schematic of the HVAC system, understand it's opearation and then start testing the vacuum control devices. maybe more than you want to do.

Heat/ac not working on 2004 Jeep Grand Cherokee Limited


look for Main A/C relay, look for fuses, or go to a/c shop and have gas check out, perhaps leaks, perhaps evaporator, perhaps condenser, but start for relay box on front passengers side, or fuses on same side

Climate zone problems


Hello, This is because your actuator door in the dash board is broken. its about $1000 to fix. Its a bad design flaw that Jeep used in their dual climate control. Many many many jeep owners have had this problem.
