Discovery Mk1 300TDI Window Prob.

2-door LHD LHS Front electric window has stopped working and remains
shut.Took door panel off and found 2-pin plug which appears to be entering
the mechanism,disconnected it and put a voltmeter on and rocked the window
switch-hardly any swing i.e. much less than a volt-should it be around 12v
or is it just some sort of sensing signal?I suppose I should compare it
against the other window but if someone knows this info. and can suggest a
few quick checks,then I can save the disassembly until I know where I'm
looking.TIA.1995 MANUAL 2-DOOR 2.5TDI

Try using one of the other switches to eliminate the switch

well, now. If it was a 4-door, and the rear windows not working, I'd tell
you "window lift control unit". It might still be so...

it hides behind the glove box and is a bastard to get in or out - the 4-door
problem and solution is described here:

http://www.discoweb.org/window/index.htm

so might be worth a look.

hmmm. dunno if the front windows are run from an ECU...

bugger. I *was* going to paste some info from the RAVE, but the sods have
encoded it so you can't cut and paste.

hangon, I'll print the page and OCR it - they haven't thought of that :-) I
do like getting the better of the copy-protection types.


CIRCUIT OPERATION
Voltage for window lift and sunroof operation is provided to the Window Lift
ECU _ (Z147) from fuses F1 and F2. The Window Lift ECU is grounded through
the B wire at ground E201.

Timeout Feature
Fuse F15 applies voltage to the Window Lift ECU terminal 3 when the ignition
switch is on. When the ignition switch is turned off, the absence of voltage
at terminal 3 signals the Window Lift ECU to start the timeout feature. When
the timeout feature is activated, the Window Lift ECU will allow window and
sunroof operation for an additional 45 seconds.
The timeout feature will be cancelled if the driver's door is opened and
then closed. The Window Lift ECU monitors the door's position at terminal 9.
Front Window Operation
When a Front Window Switch is operated, the switch grounds one of four
Window Lift ECU input terminals. This signals the Window Lift ECU to apply
voltage and ground to the respective window motor. If the front window
switch is held in the down position for more than 1/2 second, the express
down feature is activated. The Window Lift ECU will operate the window motor
until it is completely lowered.

Rear Window
The Window Lift ECU terminal 4 supplies voltage to the Rear Window Console
and door switches for rear window operation.
When a window console switch is in the 'DOWN' position, voltage is applied
to the window motor through the 'up' switch contacts. The window motors
operate because they are grounded through the 'down' contacts of the window
console switch. When a switch is in the 'UP' position, the polarity applied
to the window motor is reversed, causing the motor to run in the opposite
direction and the window to close.

Had same problem last year, ended up mine was just a mechanical stiff.

Unmounted the motor, moved the glass (be carefur not to drop it, have
someone helping u), lubricated here and there, reassembled, works fine.

I'm unsure there is any sensor, the glass "automatic descent" is timed by
the motor itself. Ie with the motor disassembled and kept in yr hands, you
push the "window down" key, then the motor runs for a while then it stops.

Hi,

Had my window regulator mechanism snap. While waiting for fix, found that
motor ran for a long time if I pressed the button. So I suspect that if the
mechanism was stiff, the motor would stop automatically, rather than being
on a timer.

Cheers!
