Power windows

[jorg50]

I have a 1991 Citroen Ax, 1100cc TRE, the drivers side has two switches one is for the driver side window and the other switch is for the passager window this one is not woking and also the passager window is not working. The switches have been tested and they are good also the motor, what has been found is when the ground terminal is conected to ground with a jumper wire the window works up or down. I don´t have a wire diagram for this car and don´t know where this ground goes to, the wires that go through the rubb grovement have benn cheked and there are no broken wires. If anybody has been through this problem and could help it would be greatly appreciated since the can not pass OT test without the windows working.

That sounds like a faulty earth connection in the passenger door where the window motor is grounded. Have a look behind the door card and you may spot a rusty connector.

It may be that the ground wire is broken inside the harness where it flexes near the hinge.

The wires that go through the harness near the hinges are good, the problem is that I don´t know where they go from there.

Have a look for an earth point at the side of the footwell, it might need plastic trim removing. If there is not one there you could always provide a new one and wire to the motor. If you do find it use a volt meter set on resistance to see if the wire is broken between the 2 ends, despite it looking good externally.

In the footwell there isn´t any negative terminal, the issue in measuring in ohms to see continuity is that i really don´t know where the wires come from.
Now the passenger window goes down but doesn´t come up but if I put a jumper wire from terminal 4 to ground it will go up, so in the up position there isn´t a ground .
The switch from the drivers side that controls the passenger side window it will not work and it´s not the switch and the ground terminals were by passed to ground and it doesn´t work .Now this is driving me nuts! .

A long time ago I had a Saab where a window was not working from the switch. It turned out the contacts within the switch were dirty and after taking it apart and cleaning them up it worked normally.

[jorg50]

After testing the switch with a multi-meter they were found to be good. The switches were over ride with a jumper wire witch proved that they were good in working order.
I my opinion there is a ground problem, where it is is the question, it needs more investigation.
Anyway thanks for your input.

Sometimes a multimeter will show continuity but if there is corrosion or dirt in the connectors it still won't teliably take a high current load.

There is an AX wiring diagram at:https://share.google/aqmD4KbNfkq2hDtaK

The text in japanese but the electric windows appear to be on page 8 (VII) with the electric locks.

The window system is grounded at M6 which is probably under the dash near the steering column.

In these circumstances, a good test procedure is to run a length of wire from a solid chassis earth point to the urilising earth terminal in the door. You then know whether it is a broken earth connection or not.

I already did that and when done the motor did work for sure it is a open ground or broken, the idea is to know where it is.

That´s true, but the switched was tested on the driver side and it worked and also when there was a jumper wire connected to earth directly under the terminal 4 witch is the earth it did work

Thank you Xantia_v6 for the for the electric diagram. I will have to take the plastics and he rug to have access to the steering column.
The second switch that is in drivers door hat open and closes the passenger side doesn´t work too.

I have taken the plastics under the steering column and could no see any ground ire under there. This ground wire has been a night mare.
my desire it to make it right because with the jumper wire the passenger side will work but the switch that is in the door of the driver side that control the window of the passenger side this one doesn´t work.
