Thread: Discovery 1 Rear Window Faults

Sam, this is, I believe, a common problem that is easily fixed. It's probably due to a dry soldered joint in the window control unit.

Try a search on that.

Yep, definitely the window ECU.

I had the same problem, rear windows only worked when they wanted to and seemed to be better once the car had been running for a while. Then one day - window goes down and that's it! No up or down!

Under the passengers side of the dash, you undo the drop down kick sort of panel below the dash, there is a black plastic box ECU that runs the windows. From memory there are 3 screws that hold it in place, including a bugger of a one to get to at the back. If you have (I think it was ABS) it is even worse as the controller for that is squished in there as well.

Unplug the box and if you are handy with a solder repair any dodgy connections, or just replace the whole box. I replaced mine for about ($50 I think) from the wreckers, or you can get them occasionaly on ebay for a little less.

Is this relevant to the front windows at all?

Both my fronts stopping doing the up/down thing within a couple of weeks of each other.

However, mine look like they are trying, in that they move a few millimeters when you push the button. I thought it was a window track issue, but seems strange that after 12 years they failed so close together.

Thanks

I had the same problem. Turned out to be a dry soldered joint on one of the relays in the controller.
The thread that Ron has linked to has all the relevant information. All up, it takes about 20min to fix.

The same ECU does control the front windows as well.

Not 100% sure, but I thought if the problem was with the ECU they would either work intermittently or not at all. If they are trying to move I would most likely think window track or motor.

Awesome, I've had this issue since buying the car and it was only last week that I was driving through the outback in 20 degree heat that I was peeved that they weren't working. Luckily being an LR owner I've got my tools on board and a gas soldering iron and my windows are working perfectly

Thanks mate just got home from a play at Bunyip state forest and the rear windows wouldnt go back up. Followed these instructions and bingo bango the windows work better than i have ever seen...
