Disco 1 rear windows not working

[Sprite001]

Hi there
I am after some help with my rear electric windows on my 1994 Disco.
They seem to work intermittently.
I replaced all 4 switches, just in case, as well as both the fuses.
The wiring diagram says there is a relay in the system but I don't know where to find them, and I am not sure if this is the problem anyway.
If someone out there who has had the same problem and has fixed it, I would be very appreciative.
Cheers Phil

This is a pretty common fault. Usually it is a dry solder joint in the PCB that controls the windows. The PCB is located in behind the glove box. If you pull glove box out you will see the control panel in a housing. If you are handy with a soldering iron all you need do is re-solder the dry joint and you should be sweet.

This guy has a good post (including pics) on how to do the fix "Repair a Land Rover Discovery electric window ECU to make the rear windows open again" (http://www.landyworld.co.uk/discowindows.htm)

Really? Surely everything has been covered at least once or twice.

Solder joint on the ECU board behind the glove box from memory, just like the posts before there is plenty of info and it's a relatively quick fix with a soldering iron.

The first Disco I bought was fine, then I drove it home and on the way home the rear windows weren't working hahaha

Its called a window lift ECU and as above it is situated behind the glovebox, 3 x 6 or 7mm bolts to remove, one of them a bit of a pain in the ass to get at, although IIRC you can remove the plugs from the ecu, and then the board from the casing and leave the casing attached to the car.

Re-solder and get fresh air again or simply slot in a replacement known good unit.
