Sorry, had to bring this up again. I just spent several hours taking the door apart before finding this thread and it worked on the first try. WOW, I feel good now....
you need a power window motor. It does matter because one of these times the banging on it/ slamming the door method will not work.. We do that at work to get the window up then we pull the plug on the window motor so the customer does not roll it down again ( if we don't have the motor in stock)
