Measure the voltage between the ground pin and the metal frame of your car (should be zero). Then switch to ohms and measure the resistance - should be very small.

Weird you are not getting power - probably should check the bigger fuses - perhaps this is a weird symptom of a shorted fan sowed resistor or maybe even a blown aux fan.
