There are 2 cooling fans on this. One is switched to the temperature and the other is switched to the AC. The AC fan should turn on Everytime the AC is turned on. I believe this fan is on the passenger side. Your engine fan seems to be working properly. The AC fan switch needs to have a signal confirming there is pressure from the AC system. I suspect you either don’t have the proper pressure in the system or the pressure switch is faulty. First check the fuses.Check the No. 1 (20 A ) and No. 4 (20 A ) fuses in the under-hood fuse/relay box, and the No. 14 (10 A ) fuse in the under-dash fuse/relay box.
