Power Windows, Sunroof and Mirrors dead on Range Rover DSE 1997

Hi.

I have a Range Rover DSE 1997 where none of the power window, sunroof
or mirrors work when controlling from centre console or the rear door
switches. The fuses are ok.
Has anyone had this fault? Thoughts?

The display say "Window not set" & "Sunroof not set" but I can't set
them as they are completely dead.

Many thanks!

Have you checked fuse F1 (10A)? That supplies the centre console switch
pack, amongst other things.

Hello.
Thank you for your answer!

Yes, I've checked all fuses. (removed them all and tested them. Also,
when in place, tested for 12V on all of them)
Also, the center switch pack get's it 12V from BeCM. There is 12V to
the Centre switch pack. But nothing happends when pushing any of the
switches.
I opened my BeCM today, searching for visible damage or corroded wires.
Looked OK.
Could it be one/or a few of the relays in the power board in the BeCM?
Or maybe the big IC in the centre switch pack?

Any ideas?

Many thanks!

You're brave opening the BECM!
Have you checked the earth connection to the switch pack, it's the black
wire on pin 6 of the switch pack connector? Also there are 5 wires from
the switch pack going to 2 different connectors on the BECM , have you
checked they are all ok? It looks like the control of the front windows,
rear windows and the sunroof all use different bits of the BECM. The
motors for each of these also get their current from different fuses so
I'd think it is more likely a common control problem. The fact that none
of these are working I'd suspect the switch pack or associated BECM
connections, but I'm just guessing.

Thanks for your post gaz!

I didn't know windows and sunroof used different bits of BECM. That
sounds kind of good. been searching at the forum on www.rangerovers.net
also. A few have exchanged the switch panel more than twice. Sounds
likely.
Thank you so much!

I will try to get an for exchange.
