Hey all, Been having hot to fair weather here in PDX (105*-75*) And I notice that my aux fan will come on when the air conditioner is running (Normal I beleive), but also seems to like to run when the AC is not on. Early mornings when the temp is around 65* the fan will come on for some reason. It will run with the climate control off as well. I dont know if its just because of the warmer weather but I dont recall my old 540 or my E39 ever doing this. The mechanical fan is in good working order and engages and disengages as it should. I am just wondering why my electric fan would want to run all the time. It shuts off when the car is off, and it isnt on first thing in the morning, but comes on after a few miles of driving. I was thinking maybe a bad fan switch? I guess I am just glad its on to often instead of off when it should be on.
