Question about 2002 Jeep Grand Cherokee

1 Answer

Defroster I have an 02 Grand Cherokee Limited and the defrost is only putting out cool air. The blower will not produce any warm air even on the highest setting. All gauges are working properly and everything else is working fine. Wanted to know if it is in the regulator switches in the dash or if it is the heater core could be inoperable. Thanks Stephen

    Is the cooling system rusty??

1 Answer

The cooling system is fine along with the heater core. I finally took it to shop and the actuator that controls the regulator was inoperable. Instead of opening correctly it was just spining around completely without stopping. I have ordered parts and will have to take out the dash to replace the items.

My 2000 Grand cherokee only blows warm air from defrost or any vent, 105 to 110 on a 32 degree morning with high fan, about 10 degrees warmer on low fan. It gets warmer when it warms up outside.Engine...


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.
