Hey I'm a bit confused now.... my drivers side window does not go down, so i thought maybe it was the switch, so i ebayed it and got a new one, well that wasnt it. so i went to ebay again and got a regulator and motor... but before i decided to take the old one out, i simply hooked it up to see if it would work, but it didnt... is there anything else that it could be? i can work all other windows, just not my own...
