Electric Window Faulty?

Heya all,

New to the forum and just put my introductory post up

Basically, NS/Passenger's side electric window is not operating, its not the fuse as have chcked this and when i press the button i do not hear any power going to the motor or it being stuck on the runners etc.

My thought process was to try the switch first? going to pop to a breakers yard later to see if i can grab one. However, can i swap the drivers side switch with the passenger side to see if this fixes it? i haven't yet as the part numbers where both different and i wasn't sure if the cabling/switching was different for eash side, so i haven't tried that yet as i didn't want to end up with two broken windows haha.

Any advice would be great

Thanks
Jamie

P.S. i have a Multimeter

Yeah swap the switch.

If that doesn't work, pop the door card off and pull the connection off the motor, operate the switch and see if the connection goes live, ensure the negative has continuity.

The wires can snap in the loom between the A pillar and door.

Window problems can be associated with the window ECU which is located behind the glovebox. Land Rover ECU Repair - YouTube watch this it might help as to the location and diagnosis

Definitely not the switch, just tested it.

It'll be the ECU - mine's the same. Previous Disco was the same.

Had the same problem with mine,took it out cleaned it up and bingo!

Cool, will take a nose at the board tomorrow. Same position on the mk1?

So, plan of attack with this window.

1 check cables at door
2 door off and check for any blocks in runners
3 check for voltage at motor
4 check window ECU

Anyone got any other tips?

Forget 1, 2 & 3.

Did mine today, ECU cracked in exactly the same place as the Sceptic Tank's Disco in the You Tube video.

One hour, fiddly to get to and fiddly to put back but windows work fine every time now.

Oh wicked, well done on sorting yours was it just the one side that had gone or had it killed all of them.

Going to pop out and try my luck now

ECU definitely isn't behind the glove box.....

They are in the 300tdi. You have a 200tdi.

Not sure where they will be in those.

Sorry.

Scratching head....... Hmmmm.

Yeah 200tdi, stumped, can't see it drivers side either.

Google?

Don't bother 200tdi's don't have a window ECU AFAIK!! drivers front motor is the master switch all others are simple slave units.

Right, ok that sorts out me trying to find it then haha.

Any ideas on how to approach passenger side window not working, I know it's not the switch or fuse?

there's 2 relays under the side panel in the drivers footwell. Yellow ones IIRC. swap them round and see what happens. failing that live feed to the motor to see if it motor is fooked.

Will try now, don't disappear yet thank you

Drivers side....

Hang on.
