After a long drive (well long for me anyway) from SSF to SF and back i parked the car and watched the rest of the le mans race. After it was over i had to pick up my syster from work so i start the car and hear a humming.
Pop the hood and see the aux fan running
But the belt driven fan is working just fine? So i drive it around like this thinking the aux fan would shut off after it has wind hitting it but its still running.
What could be causing this? i dont run the AC only heat in the cold mornings but it was warm yesterday so i didnt use it.
Thanks in advance for all your help.
