Heater problems on my 2000 Jeep Grand Cherokee. Please Help!!

I've got a 2000 Jeep Grand Cherokee & the Heater seems to blow warm air on the driver side vents. But blows nothing but cold air on the passenger side vents.It 's even like this when its on defrost. It has auto temputure contols. Is it possible that there is 2 seperate thermostats?

    If this is continual problem with jeep, shouldn't they pay to replace what is obviously a faulty part of thiers?

    I have basically the same problem with my 2003 Jeep Grand Cherokee. The driver's side stopped blowing warm air and now neither side blows warm air. I've been told that it's the heater core but we've never smelled antifreeze through the vents or had a fog or a haze in the windshield.

    exact same problem. Anyone in southern Ca please reach out and let's organize so the dealers will fix our issue at their cost. this obviously seems like a manufacturing defect.

    I just experienced the same problem last week on my 2000 jeep grand cherokee. I took it to a mechanic and he told me that it would be $500 to $1000 to fix the problem.

THis is a know problem with Jeep GC. If only one side is cold and the other is hot and there are no controls error codes. It is likely a broken temperature blend door on the faulty side (w/ dual controls). Dealer charges a lot to fix ~$800. There is a kit and instructions sold on EBAY to replace the part for $100. Seller claims that a relative novice can fix w/o removing the entire dash board as the dealer does. Has sold hundreds of kits....people seem satisfied....you may check it out. Search Heater Blend Door Jeep on ebay. Replacement parts are aluminum instead of OEM plastic.

Self Diagnostics on HVAC system. Jeep GC has built in diagnostics and will return error codes on the temp display if it is otherwise. Simple to display.
1) Press A/C and Recir button simutaneously
2) Rotate driver temp control knob clockwise then release buttons
3) If no controls error a code of "0" or "00" will be returned.
4) Error codes listings can be found on-line if anything but zero

Dealers charge $45 to run the same check

There are 2 seperate zones for the drivers and pass. side, but they use the same thermostat.
There is a blend air door motor that controls this.
The one on the pass. side is probably bad.
These are kind of hard to replace.
There are on the bottom of the heater box and you need a philips screwdriver about an inch in total length.
There is not that much room between the bottom of the heater housing and the floor.

I have a 2000 Grand Jeep Cherokee Laredo (6cyl). It was blowing only cold/luke warm air. I replaced the thermostat. Still blowing the same only now the radiator cap is cold but hoses are hot. ...


It is likely you have air in the system. Park on an incline, take the radiator cap off, start the car, let it warm up until the thermostat opens, fill the radiator until it stops going down. See if that doesn't get you some hot air. If not, try the other steps I have in my post at http://www.fixya.com/cars/r6235876-no_heat_fan_blowing_cold_air . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me.

This is a common problem with WJ Grand Cherokees, it's called a "Blend Door".

In the heating and cooling system you have doors that open and close to give you warm and cold air and a mix of both.

What you have is an arm that pulls a door with peg on top, the peg tends to snap off. As you said your dealer replaced the blend door or doors I would take it back as is has blend door all over it.

Yahoo and youtube "jeep grand cherokee blend door repair"

I had a 02 limited blend doors issues (note the issueS) and was lucky to have it still covered.

I do hope this helped.
