Looking for someone to help a brother out.

My neighbor has a 94 LeSabre that has an electrical problem with the power windows on the right side only. Hoping someone has better elec. knowledge than I have. Here's what I got on the right front window:

DIAGRAM AND TEST RESULTS

nothing
lites when pushed down \/ lites when pushed up
\ (lt.blu) /
(blk) up (dk.blu)
switch
(tan) down (dk.blu)
/ \
nothing constant (+)

The right windows do not work with either the master control switch or the right side individual window switches. Left windows work fine from either switch on left side.

Anyone have any ideas or possibly a jumper solution just to get the window up?

Please don't yell at me if I posted this in the wrong section.

the diagram didn't work so well. If you "quote" the mess in the middle, the diagram will look right.

umm, been a while.

are you getting any voltage to the power window motor?
if no - then verify switch sending out power
if yes - then probably a bad motor (verify voltage on known good window (ie other door))

if no voltage at the motor - and voltage out of both switches - trace the wires back - might have broken a connection somewhere.

I haven't torn the door apart yet so I don't know which wires go to the motor. All I know right now is that I have no power to the up side of the switch. Should there be a constant power source to the up side of the switch as well as the down side?

i would expect a voltage of either +3, +5, or +12 volts to the switch

but depending on how the switch is built - you can have out 3 wires depending on what voltage is applied the motor could spin opposite directions.

it can go + - + or - + -

or 4 wires which is different or 2 coming out, and the switch works different.

first thing you need to find out is power getting to the motor.
if not then you can bypass the switch - to move up/down - then switch is bad. best way to look at electrical issues for everything.

Start at the end and see if you are getting what you expect.
if not work back till you are - then verify the part between is broken.

Anyone know where there are free wiring diagrams online for Buicks?
