I have a 2009 Grand Caravan SE. Recently this issue has come up this summer. The AC works fine. However after running for a few minutes, and sometimes good 5 minutes, the blower stops working and the air blows at minimal pressure. After turning off the AC the blower pressure resumes automatically within a minute. If I turn the AC back on, the pressure stays for a few minutes before going away. Mostly noticed this issue on highway on long drives. Looking for some help before I go to a mechanic. Tia.
