Hi! I have a 1996 Pontiac Grand Prix. The Driver Side window has started to do something strange. When I push the power window switch button down it goes down (quickly) about 1/2 way then goes real slow then stops. If I try to push the window button up it does nothing. If I turn the car off, wait a minute, turn it back on the window will go up fast and close. I took the driver power window switch out(which also contains the passenger window switch) and it has a circuit board, etc. in the whole unit. The passenger window goes down and up perfect. I am trying to determine is it the switch or the motor/regulator. I have read some people say its the switch but its very expensive (like $60) to guess its that. Is there a way I can test/determine if its the switch or window motor? Doesn't seem like the window motor because if I turn it off and on it goes up or down (1/2) before it dies. Any help in determining if its the power window switch or motor would be great as I really don't want to take the door apart if I don't have too.
