2002 grand cherokee Limited air hardly blowing out of any vents

Have searched throught several forum posts and have read of similiar problmes but not exactly like this. A/C and heat work fine, blower motor appears to be blowing fine but air is hardly blowing at all out of any of vents.

Also, as the truck heats up the air flow appears to blow just a tiny bit harder out of vents but not much. Its cold here in Northern IN and we need the heat to BLOOOOW.

any help would be greatly appreciated.
thanks all.

check to see what codes you get by following the steps under AZC self-diagnostic mode at Jeep Grand Cherokee WK - Climate controls

code 52

no it's the recirc door, different then blend doors. it has propably fallen off and is sitting atop the blower motor blocking airflow. i believe you need to take dash apart to fix properly. the workaround is to jam the recirc door in either cabin or outside air mode. you will not be able to switch between the two.

52 dose not sound like thats whats causing your original posted problem of weak air.

have you checked for anything clogging the vents?

Figure it out?

Gracie, were you able to solve the issue? I'm having the same problem (haven't checked the codes, but your description fits perfectly).

Thanks!
