The passenger door window on my 1990 NA LWB doesn't work. There is no sign of life not even relay clicking. The drivers side works fine. My 1991 SWB TT N/S window has been intermittent before as well. Any ideas what I look for?

There is a small black control box in the drivers door that often gets dry solder joints and causes problems intermitantly.

Might just need going over with a soldering iron :)

I had the panel off yesterday fixing an intermittent speaker connection, from previous owners. The classis "Knot" joint and "pliers" crimp! (obviously eco friendly)

Is the control box the black unit roughly in the middle off right, about 4" x1"x1" in size?

Sorry to sound a moron.

Yes that's the one, fixed to the door just below the handle area :)

Contains relays for the windows etc

Take the PCB out and check it for bad joints.

Thanks for the advise Re-soldered all the joints, which didn't look too bad. Also fettled switch assy now working fine. Also did the cruise control mod so now good for 140+KM. Easy when you know how!

Stiil need to get a propshaft though. Does the one piece do the trick?

cruise control mod?

Good site for fixes.
