Wj Low Air Flow passenger vents

I know this has been hashed, just can't find the correct link to my problem...2002 GC Limited, auto hivac. Low air flow from passenger upper vents. I know the Recirc Door is not working, I have a fix for that coming, but either in full open or closed position, I get very low air flow from the passenger vents (all 3)....Hivac has error code 52. Airflow at lower vents is fine, defrost seems to be good, just the passenger side air vents.
Thanks Okie Steve

If I recall, I thought 52 was a blend door code.

From Blendorstore.com: The two common symptoms are: You feel a draft coming from under the dashboard on the passenger side when the vehicle is moving. The other symptom is, you have the fan turned on HI and there is little or no air blowing thru any vents!

There are two ways to check for a recirculation door failure if you have the Grand Cherokee with the Automatic Zone Control system (AZC). The first is you can read the fault codes of the AZC system.

To read the AZC fault codes: See above description

19 or 51 – AI (Recirc) door travel range too small

20 or 52 – AI (Recirc) door travel range too large

The above codes indicate a recirculation door problem. #52 is the most common.


The problem is that the system(s) for a code 52, is low air flow on ALL vents....I am ONLY having problems with the Passenger side. That is what the problem is. Just fine from driver side vents, very low (with fan on full) on passenger side.....steve

I have the same issue probably gonna try to pull the glove box out and access the recirc door to see whats going on. I know that recirc option in my car does not work at all. the light comes on but the motor does not. so if i had to guess the door may be sitting on the motor. But thing that bothers me the most is the fact that i get cold air from outside blown in. it does not do it all the time but most of the time. i was also considering on getting a replacement that mopar makes.
