Troubleshooting the "Power Window Inoperative" Problem

[Peter Golledge]

Charles,

I would try temporarily moving the connector to another of the switches on
the drivers door "panel".  I had one of these go bad such that it ohmed OK
but would not pass enough current to drive the window motor.  Also may want
to swap out the switch in the passenger door temporarily to verify that it
is OK.

I did end up replacing _all_ of the wires in the drivers door on my 89
200TQA as the intermittent connections were driving my wife (and I) nuts.

Subject: Troubleshooting the "Power Window Inoperative" Problem

For the weekend's projects, yesterday I successfully fixed the bobbing
speedometer by pulling the instrument panel and re-soldering.  It now
works!!!  Yaa!!!

Today's project was the passenger side window.  Over winter it went down but
wouldn't come up.  At the time, I did the temporary fix, power directly to
the wires and this put them up.  Today I set out to fix it as per the
instructions at

That article assumes that you're able to find a broken wire.  Not only was I
not able to find one visually, everything seemed to check out with a
multimeter.  I documented what I found hoping someone here could give a
suggestion:

each plug has 5 pins that look something like this diagram:
 ____
| 1  |
|    |____
|      2  | 
| 3       |
|     _4__|
|    |
|_5__|
 

On the plug in the driver's console that controls the passenger window:
the wire from pin 1 is brown and appears to be always grounded
the wire from pin 2 is white and connects to the wire from pin 1 on the
passenger side...connection checks out with ohmmeter
the wire from pin 3 is red/blue and measures 1.5 volts with ignition off, 12
volts with ignition on
the wire from pin 4 is black/green stripe and connects to pin 5 on the
passenger side...connection checks out with ohmmeter
the wire from pin 5 is also brown and appears to be always grounded

On the passenger side,
the wire from pin 1 is white...connects to pin 2 from driver's side
pin 2 is green (goes to passenger window regulator)
pin 3 is red/blue stripe and measures 1.5 volts with ignition off, 12 volts
with ignition on
pin 4 is black (goes to passenger window regulator)
pin 5 is black/green strips and connects to pin 4 on drivers side

Using switch on driver's side, unable to move the passenger window in either
direction.
Using switch on passenger side, can move window down but not up.
Can rig passenger side to go up by grounding pin 4 and connecting pin 3
(live) to pin 2 

Switches seem to check out by connecting them to back window.
Window regulator seems to check out because it works if power applied
directly.
Wires seem to check out via ohmmeter, and no obvious breaks or cracks that I
can see.


Hoping someone's been here before and can see something that I might be
missing.


Thanks
