In all honesty Rooster I suggest you get the switches and window regulator voltage tested - only sure way to find the fault. One other possibility is that there is a break in the wiring harness going to the drivers door and it shorts whenever the door is opened or closed
Didn't think of the door idea! Maybe opening and closing a few times weakens it, but then again a new fuse fixes this everytime!
Ok, so if I test all of the voltages and something isn't right, what do you think the next step would be?
