electric window fault

[Britman]

Hi I have removed door card and am stuck now. I am usless at electrics.

I have tested black plug that goes into driver side convertable window motor then flicked switch and tested voltage it flick at 5 volts i though should be 12?

The switch clicks and light dims like does on working windows. It clicks in door too but dunno if this is from swicth it is all one click the noise. All othe rwondow work fine is only driver that is issue. It needs doin as on cab they rise after closing door a cm and now let in water.

I know this isnt vw but i love this site is best forum around and sold my mk3 tdi but surethe mechanisms arnt to different and sure people must of had an e36 bmw before

Is there a way of finding relays to see if they are problem are there seperate one for all windows? i find fuse/relay box confusing it says number i.e for front window lift but no number on fuses etc :S.

can anyone help and post pics of what relay and where is for drivers window. I am stuck what to do next.

I hope isnt motor as the bolts that hold onto bracket just turn the hole bolt and nut they wont loosen and only way to get motor of is to remove whole bracket arggg.

I could but a motor and plug it in but seams a waste if i dont know it is that, i was thinking if was a relay for each front window could swap them over to see if works.would just buy a motor but on ebay want 25-30 quid for one.
ee
sos help someone can help as door cards all stripped off now, cheers steve thanks in advance i just cant figure out where the relay is for the drivers door or whether just to risk a new motor for it. Maybe i could put in another section but cant see any for vw group cars. really sorry  but am stuck with it and am usless with electrics and is letting in water some day and windnoise

also any ideas what fuel gauge issue could be? is goes up to just below minimum but stops i kno whas over £50 of fuel in it, looked at backof clocks but plugs seam ok, dunno if is pod or fuel tank sensor

What car is it then?

i personaly would say it's a window regulator as the lights are dimming showing a drop in amps, so the window in theory is trying to go down (or up) but isnt, to be doubly sure you could try search for the wiring diagrams on google or a bmw forum to check the wiring, i assume it's a bmw as you mentioned it, and i dont think its that uncommon for a regualtor to fail to be honest, dunno about the fuel gauge, could be a fault with the sender inside the tank, i work for land rover and the freelander 2's have a slight issue on some where a pipe or cable tie on the sender catches on the float so cant go the full travel, check and make sure it's got a good earth as well that can cause you problems aswel
jope that helps mate

I would also say the window issue is down to the regulator,what happens is (im talking vw here) because the cable that drives the window is wound metal (kinda like a metal rope) over time it starts becoming frayed and it all gets caught up in the motor which then obviously jams the window when you try to put it up or down,you should be able to see if this has happened by inspecting the cable and the regulator,im sure bmw's ant that different to vdubs.

thanks for replies, so the whole motor unit? i was thinking of buying the whole thing, it is attached by metal arm brackets silver ones andcan only be removed to tak emotor of by hacking bolts of as are rivets on so just spin when try to undo bolts and nuts. yes it is a e36 3series convertable, but dunno how simlar they are to v, there is a motor an da black part on that i reakon it is the bit inside that too is that the regulator? all one piece anyway i think, thanks someon eon ebay had a whole piece motor brackets and regulator for £30 p+p inc from a m3 convertable dunno where else sell good spares any idea as ebay can be dearer on some things, thanks

Some said coulld be a loose wire in fuel tank sounded compicated , well for me anyway to look it is under seat someone said then hadve to get a of  aplate of some type to see into tank

I've done a few at work. The regulator is held in with rivets so you'll need to drill them out. Even with my air drill its a long task! I advise you getting a new regulator as you'll see on the window there's a sliding piece which is then connected to the regulator via a ball joint. This joint on the arm bends and if its not at the correct angle the window will keep popping off the reg. Providing that the motor from the ebay one works I would try it for that price.

Incidently, what is your problem? Does the window just not go up/down or does it not seal the window? The reg itself rarely siezes, they can get stiff though but the motors are notorious for failing now.

Your fuel problem is another thing I've encountered. First thing to check as you've said already is the wire at the fuel sender. If you grab the rear seat base from the rear footwell side, yank it up, you'll see the circular plate. Undo the 10mms and the plug is there. Hopefully you'll see the wire broken as it enters the plug

cool mate thanks for reply. I will buy whole piece when get window regand motor and brackets as wont matter then if is all hacke dand bent so much old one, it annoying the seal it in.

Good news the right side wire is loose out of plug? I am usless at electrics what do i do now is it clamped back in :S or soldered back in not sure how goes back i will have  acloser look but thought id post, thanks   by the way it is the white plug above blue one with thinner wires and is snapped off at the base part on right side where goes into plug  cant see how it can be fixed?

I guess may need a new pin and then soldering on, as cant replace whole loom that goes round car. I just hope i sonly one snapped as i heard are more under the pump too in tank
