Heat/ac not working on 2004 Jeep Grand Cherokee Limited

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 .

You have a leak in your air conditioning compressor Your system works on the reheat principle All air passing through the system is cooled and reheated before it enters the cabin this sould be dehumidified air but it passes through the heater core and sence the air is not dehumidified you are getting condansation as the air flows the heater core that is heated by the engine heat and the water is from condencation because of the leak in the ac compressor The unit is a press fit in the center of it and fials unfortinatly a lot with this disgien of compressor

hi
there is no recall from jeep (there should be) your blend doors are damaged or broken. jeep will quote you around £800 to fix. log on to heatertreater.net they have a diy quick fix that will last the life of jeep. you can install the new blend doors that are metel (not stupid plastic ones jeep use) in around half an hour, this really does work as i have installed a few of these kits with no problems.
hope this helps

sounds like the clutch field on or bearing on the front of the compressor went bad take a closer look at the pulley on the comp. and see if there is any debris or melted plastic coming out behind the pulley,if so the clutch,field and bearing should be replaced,hope this helps

hello, this sounds like a bad blower motor resistor!! its cheap and easy to change..if you need more info on locations let me know,, good luck.....marty

It could also be the rheostat that controls it. it's on the fan plenum under the dash. inserts into the plastic plenun.

your blend doors are broken a common problem for the jeeps 1999-2004 e mail me at [email protected] and i will send you a link to a web site for a repair kit that will cost les than the 1200-1500 a dealer will charge to fix this

the blend doors have broken...you will need to remove the heater/ac box to replace them
