My drivers side power window decides when it wants to work. sometimes its fine, others it only goes down and ii have to slap mydoor for it to roll up. guessing i have to buy a new motor and everything. took off the door but there is a piece of sheet metal blocking my pass to the motor.. anyone know how to fix this in Az? or know how to install and can give me pointers.. I know i come on here a lot asking for help, but so far everyone has been awesome- thanks in advance for the help!
