As my titles says, the front windows in my 96 D1 have stopped working. I found a thread on this forum about fixing the rear windows but it refers to a ECU repair thread on Landyworld that no longer exists (my D1's rear window work fine). Could the front window problem be a similar ECU issue that affects the rear windows?

It's the same ECU for all so IMO it can affect the fronts the same way like the rears, would be a good move to rule it out before starting some complex troubleshooting which can be a nightmare ...maybe you can find a working one at a scrapyard

Thanks.

I just found another 'how-to' for the rear windows, that shows me the location of the ECU: https://discoweb.org/window/index.htm Now to figure out which solder joint/pin is for the front windows.

If they’re dry joints , they’ll be obvious ..

The electric window ECU plays big part for the front windows and a minor part for the rear as there’s only a single wire involved, which is the supply out of the ECU to the rear window switches/motors.
A stated dry joints on the PCB are a known issue within the ECU.
There’s also the fuse for the front windows is #1 in the upper aux fuse panel.

Turns out it is the motors that are caput. The LH motor has failed completely (fortunately with the window in the up position) and the RH is on its last legs.
