1992 power window problem

[wb3hyb]

hello
have a 92 lesabre with intermittent pas indow problem. randomly will not go down- but old trick- open door with window switch ( works same from either door) down for that window - open door and close with power still applied by switch- window then works for several days- cant seem to find wiring diagram on line - sounds like brushes in motor- but never have problem in going up - are there limit upper and lower limit switches or is it current controlled inside motor - when the window wont go down, sounds like relay in the door- brushes with poor contact dont make clicking noise . since i am only driver havent taken door apart yet.
any partial wiring diagrams available?
thanks

Welcome to AF. Most likely the motor is bad or the connector at the motor is corroded, autozone.com/repairinfo has some body wiring diagrams.

Try removing the door panel and checking for loose connections first. All of the wiring is very easy to see and check even without diagrams.
