The car is a S4 N/A model first off. The blower motor that was in my car never worked so I replaced it about two months ago. The one I put in worked but every time hit a big enough pot hole it would stop, and start again if I open and close the door. I thought it was a short in the logicon, so I replaced that and the same thing happen. Now the blower only works if the glove compartment door is open. As soon as I open it, its comes on instantly, and once I close it, it turns off. Has anyone came across this or is my car just possessed?

 

Clearly, you have a wiring problem and it would be logical to remove the glove box and inspect the wiring to the blower motor to see what's going on.

If that doesn't work, it might be time to call Father Karras.
