    1999 Deville - can we repair the driver's Window switch ?

    The passenger right side window goes down but won't go UP.
    The driver side switch does not work anymore for the passenger window,
    but all other window works fine
    The last time i succeed to get the passenger window to go down was by pressing the driver side switch down 30 to 40 times. but that does not work anymore.
    I suspect a bad driver side switch.
    How to be sure that the problem is the driver side switch

    Can we repair the driver's Window switch

    I replaced the motor and the new one goes down but refuse to go up

    Any help or link will be appreciated.
    Thanks

    If the motor makes it go one way it's not the motor. Power just gets reversed to it to make it go the other way. If you think it's the switches you'd need to get new ones, either from the dealer or parts store if available or a junk yard. It could also be that a wire wore out and broke between one of the doors and the door frame.

    Get a replacement off ebay for the drivers switch and be done with it. About 40 bucks will get you one or all of them of you're lucky.

    The main driver switch has a circuit board, no repairing the board but the contacts in the switch itself can be cleaned
    requires a little time and patience q-tips and a bit of electrical contact cleaner and some dielectric grease (very small amount on contacts )

    you can take it apart to see if any tiny dirt is in it. It is-not fixable unless there is a loose pin or dirt. SWAP WITH REAR DOOR to test it....easy to swap .back and forth. I did this and confirmed the [both] switch is fine.

    ----------

    put 12dc direct to module plug from small extra battery and alligator clip wires ...the only plug with thickest blue brown wires on the end of module. Windows go up and down...confirmed motor okay. Widow was slightly of track
    sol check for this. The switch is good confirmed with a rear door swap. Now the module does click but suspect this is the problem. Will swap with rear door one to check it. Other than this I might consider a wire issue somewhere yet I doubt that. I think it likely is the module...check this idea
    tommorrow
