The compressor and the condenser fan in the rear are both running.

I'm trying to check evaporator fans, but how do I use my multimeter (or a battery) to test these evaporator fans that have 4 colored cables: red, black, yellow, purple? Should I just apply 12v DC to the red and black and see if it spins?

Edit: if I check continuity (ohms) on the red and black I do get a reading other than Open Loop so seems OK.

The evaporator panel seems to have a thermistor too(?) and that also tested OK for continuity.

I'm not sure what else to check or where to find other thermistors.
