Window Wiring

[Frantic]

Hi Guys,

 

well i've asked a similar question on here before sadly to no avail.. so am trying again as one of you must have come across this and could help us (me :-) out...

 

Right i've many electrical glitches on my 2000W alhambra 1.9TDi PD SE.. but the one i'm hunting for right now is window related.

I've had the dreaded window wont go up problem on my rear passenger window... and after checking the TIS disc found that a grey wire has no 12V on it..... i've checked the wiring betwee the door and the pillar and its sound...

there is no 12V on the car (pillar) side of the loom...

 

I've started to trace it back the wire runs along the passenger footwell and up behind the dash... this is were i struggle...

how can i find where it goes now??

 

I know its source comes fromthe CJB under the steering wheel.. but that a different colour wire the supplies all four windows.. of which the others are working. so somewhere the four wires join but where is this point??

 

I presume this area is subject to corrosion of some sort and is most likely the area of my other issues too... (cruise control not being settable, trip computer only one funciton per power cycle etc lol)

 

Any help would be great..

 

Thanks.

Is it actually a plain grey wire or is it grey/red grey/green or whatever.

 

Is there a rear window isolation switch in the console ?

That was my previous post.. and erm.. well my bad.. its a Black and green wire.. i wrote the post above from memory of the problem ready to try and tackle it again now that the snow/freezing etc seems to be fading away..

 

Cheers..

 

Oh.. and yes.. there is an isolation switch in the door.. TIS fault finding procedure had me check that.. and it appears fine?

The black/green wire from Pin2?

 

If so it becomes a Grey/Red wire at the CJB. There are two spurs on that run, one (S137) "Under dash panel, passenger side" and then again (S135) "Vehicle Floor, RH B Pillar"

 

I would remove the tape around the loom running under the passenger scuff panel and find it there, then carefully remove a piece of the insulation and test continuity back at the door - tape up when done!

 

If thats all ok then because its a spur it's most likely done within the loom - the downside of that is that it could be anywhere within the cabling back to the CJB. Personally I wouldn't be that concerned with finding it, since its a spur and you know its ok on the others doors just run an additional cable from one of those doors and chop it in.

Hey Mirez,

 

Thanks for that.. and fancy them sticking it anywhere along the loom lol

Ok will do a test along the wire.. and if it does indeed seem ok.. then i'll chop one from the front door. I'd have liked to have found the fault source as i've got a few faults which may also originate in that area.. (one shot trip computer where you only change once between power cycles, lack of cruise control..)

 

I'll keep the post upto date with my findings in hopes of helping others too.. (well i will when i get opportunity away from work to sort it).

 

Thanks for your response tho, much appreciated!
