window lift problem

Post by 164EVER » Fri Feb 07, 2020 6:43 pm

Hello I'have a problem with the front left window lift on a 3.0 V6 1988: :shock: switch OK, wires continuity OK, motor OK, fuses OK, works with 12V direct from battry but does'nt lift with the Window Lift Control Unit (siemens) unless all others lifts do work :shock: Someone has an idea ??
And I'am looking for a right one cause mine has somme teeth broken on the white plastic pinion :?
The fun is I'll have the same problems on my 2L TS 1989 :lol:
Tomorrow I'll take the TD's WLCU to try it on the V6.

You write that the switch is ok, so you tried the switch on another window?

Then the only thing is to try another unit, as you planned, did that work?

So does anything happen to the unit (relay click) when you press the button?

No nothing there is no click to hear with original unit.
If I try with two separates relay and with the switch no click to hear.
If I inser a wire in the connector I hear clic but the window still doesn't move.
Sure the electric window lift engine does work with straight in line 12V it raises and goes down when plus and negative are inverted.

Today it does lift up and down just had to put two +12V in the switch and connect orange and orange/black wires to yellow and yellow/black wires and throw the electronic siemens unit away. :D

Good that you had it fixed :)

Has it changed functionality without the unit, that is do you have to hold the switch all the time for the window to move? And does it also have power with ignition off?

Yes Of course I have to hold it and it's on permanent plus so I can use it without ignition. (Have no baby or dog).
