No power windows... help!!

[wyze]

alright this is so far where i stand

fixed most of the electrical bugs in the car but stuck on windows now

-so windows/sunroof don't work
-wipers only work on full(when i close the driver side door the opereate by themselves, when i open the door the stop)
-weird problem now when i close the driver side door the interior lights come --on, when i open they go off
-it says that the brake light is out, but just replaced the bulbs


i changed the fusible link, rm, gm, lkm, ccm, replaced all the fuses

i'm getting power at all the fuses(had to rewire a few)
i'm getting power at the ppr

i checked the red/violet wire off of the gm (white holder) not getting any power to it

swithces aren't getting any power
wires seem to be in good shape, cleaned all connections

i looks like the p.o. had alot of wiring done(very shitty work), i got tapped up wires everywhere

cleaned all the switches

there's no pin in ppr relay 8 i jumped 8/6 & 2, 6 & 2, no luck

i don't know what else to check

Something wrong in the wire loom going from A-pillar into the door.
Usually they break. Remove the rubber where the loom goes into the door, pull the loom out and check.
Could look like this one

alright i'll check it out

but for the lights it seems that the polarity has flipped??

another thing

for the ppr, can i use just any relay(same pin out style of course), or does it have to be bmw?

[shogun]

No need to be from BMW, there are many after market relais. As long as the same pinout, it will work.

excelent, i've got quit a few laying around

thanks!

[wyze]

the loom is ok ripped it apart and the wires are all in good condition

BMW uses a 'positive ground' type system for their lights. Polarity is reversed.

alright found that problem
next

does anyone have a pinout diagram for the gm and rm??

[PaulJ]

In all E34s, the battery negative terminal is directly attached to the automobile chassis making this a negative ground circuit. The Electrical Troubleshooting Manual clearly shows this to be the case and shows the external and internal lamp filaments connected to the chassis ground. Forget this "positive ground" crap, get a set of prints for your car and go to it. If the PO has really screwed the wiring up and your door harness is OK, you'll have to run it out one wire at a time. It bothers me that you say you had to re-wire some fuses to make them work. Fixing this ain't rocket science, just following lines on paper. No magic bullets here, jump into it and you'll get the hang of what BMW (as well as most other makers) is doing. Good luck.

Wiring diagrams are here, select the right diagram and then you have to study what goes in and out of GM and RM.

alright checking through the diagrams

checked pin 4, pin 5 on white connector on gm, not getting any voltage to either of them,
ppr is not clicking when being moved,
jumped connecter 6 & 2 on ppr, no windows no voltage a pin 4,5 on gm
jumped 6 & 4 on ppr fuse pops

so i guess i have to rewire the gm connector??

[wyze]

alright just finished rewiring the rear fuse box...

so far here's what i got

first time i've ever heard the rm clicking!!
but...

getting 12volts at gm pin 4
jumped pin 8&2 on ppr sounded like the rear passenger door window was trying to work on its own, ripped off door panel and motor was hot, so was trying to work
wipers were going on by themselves, door open and closed
headlight cleaning system was working when i jumped the pins by its self
interior lights work when the door is closed(bottom setting, not when door is open)

and i'm getting 0.31volts at pin 15 white connector on rm

well i'm going to be picking up a ppr monday, should there be anything else i should check in the meantime?

and what can i do about the lights, high pressure washers and wipers?

help please so close!!
