    '93 4 door SedanDeville drivers window stopped working

    Hi I tried doing a search here but could not find info for this model/year

    Drivers window today ceased to roll down, it is closed all the way up

    With volt meter the up and down pins of switch properly put 12 volts when switch is pushed in to apply voltage to either up or down wires to motor

    All other doors windows work from drivers master window switches

    I figured out all needed and removed inner door panel
    When drivers window switch is pushed down I can hear a CLICK somewhere about middle of inside of door each time down button is pushed but the window does not move at all.

    What is common failures for this ?

    Does this model/rear have one of those fast down window controllers and it fails ?
    Any way to more pinpoint if its that, the motor or regulator so I know what to look for or replace ?

    How the heck do you even get between the 2 metal skins to do any repairs, saw a few holes but could barely get my hand in just a little bit

    Thanks for any guidance

    Re: '93 4 door SedanDeville drivers window stopped working

    When my '95 Deville driver side window would`nt go down about 2 years ago,i took it to my local mechanic and they found it to be a bad window motor.I watched them work on it.He tapped on the old motor a few times,after removing the interior door panel,which caused it to intermittenly work.Apparently,the inner workings of the window motor just wear out.My old window motor was original and a new one fixed the problem.
    I was just happy when the original window motor failed,my window was in the all the way up position too,keeping the elements out.

    Thanks for the info

    For the heck of it with door panel off, I knocked about center of inside metal door skin while holding down button and after couple knocks the window then rolled down

    I then ran about 15 cycles of fully open and closed with no problems

    So not sure if problem is the motor or some relay for the fast window down feature

    For now I put the door back together and if happens again I'll at least know what it takes to take the panel out

    Thanks
