Why can this be?

my tailgate window won't open on my e34 and there's no sound from the handle when Its activated. Solenoid problem or wiring fault ?

Anybody had this happen before and if so what did you do to fix it guys/

apart from that it's a great car especially as I've just got it back on original 15" crosspokes and taken the 17" r32's off. great wheels but no good in potholed and speedbumped Sheffield.

I can now parambulate around like a geriatric on horlicks

I have heard these can be prone to broken wires where it hinges.

Check this out......

BMW E34 Touring Rear Wire Harness Repair Layout

The repair wiring harnesses for E34 touring models are universal for ALL applications (Europe,

Japan, US, etc). The part numbers, as noted in other resources like ETK/websites are:

61 10 8 365 702 Right main harness

61 10 8 365 704 Left main harness

61 12 8 355 153 Rear window defroster

63 25 8 359 099 High mount stop light

The high mount stop light wires (two wires in one sheath), and window defroster wires (two

wires in one sheath), connect directly to plug ends behind the grommets where the harnesses enter the D pillar. If you observe how things are assembled as you are taking the old wiring out, you will see how they should go back together. At the other end of the respective wiring, the high mount stop light has two spade ends that connect to the back of the stop light, while the defroster wiring needs to be spliced in to the leads coming off the grid on the rear window. Cut the existing ones 4 or 5 inches from where they are attached to the window and solder and shrink wrap the new ends to them.

There are, however, slight differences in coloring code for some of the wires in the main repair harnesses vs. existing wiring. This chart serves two purposes: 1) display the differences so that it is easier to match up wiring at the splice ends of the repair harnesses with the wiring that you will find inside the car, without going back and forth between your old wiring harness or the plug ends in the tailgate, and 2) layout the function of each wire in a format more focused than what you will find across multiple pages in the ETM or Bentley. This way, as you note any damaged wires in the existing harness, you can immediately identify what problems they were causing (wiper never returning to park, central locking not working, etc etc). Note: There are two white/green wires in the left repair harness. You must test the wires to determine where they lead to in the tailgate so you can assign them correctly with the wiring in the main harness.
