WindowProblem

1987 Range Rover Classic
One front window and one rear window opens.
Before getting too involved in replacement parts does anyone have knowledge of this problem and hopefully a tried n tested fix
Appreciated any advice

Often it's the switch pack failed. Does the rear window open from the rear switch?

yes both windows open from individual switches

had another look at switches
the two that work drivers front and passenger rear work in any configuration of swapping round switches
when you operate switch for front passenger window you can hear a click so assume power is getting as far as window mechanism
from there im baffled and seeking advice

There will be a relay somewhere I would guess as the switches cannot carry the motor load. That being the case, I would suspect a duff relay as the first possibility.

thanks for that
get a minute ill investigate

would the relay im searching for be generic or specific to window operation ?
thanks

Wammers will be up tomorrow and put you right

In the meantime I'll bore you - Could it be the "one touch electric window control unit" ?

If you take the liner out of the centre cubby hole (4 PHILLIPS SCREWS) you'll find the control unit and two relays hidden underneath.

You can prove it is the control unit by taking off the plastic cover, (it just unclips) and on the circuit board inside there are 2 copper coil relay switches with a contact on the side.
If you flick the contact on the side of one of the coils with a finger, the windows might work.

Landrover want about 60 quid for this thing.....IF you can get one!
Replacement on Ebay for 18 quid

so far nothing emerged on the relay or a fix to the problem but im sure someone will pop up with a suggestion

Power to the motor? Door card off and have a nose if electrical or mech.

will follow up dragon walkers advice as soon as i get a minute
thanks for all suggestions

had a look in cubby box after taking out liner but the one touch window lift control unit is not located anywhere in that space hidden or otherwise
believe part no is PRC6859
any suggestions on a 1987 range rover classic where this part is located ?

still looking for one touch window control unit without taking anything to bits yet

you probably wont solve it online, action needed

still handy to listen to folks who ve owned them longer than me

are all four window motors identical or specific to each door left and right

If you can get hold of a nanacom you can go into the becm and operate the window from the nano and that will prove if its the motors or the switch pack
