I did check the door harness for broken wires,but found none,will check again though.it does stop the kids playing with the windows, but would be nice to have the switches working.i did have a rear door locking motor play up a while ago and that was a broken wire in the door harness.
If you check again what Renaultbiler said, he said check the door connector, not the wiring for breaks. The door connector is a multi-pin block on the loom where it is joined to the loom in the car. You need to open the door fully, then remove the door connector which has a plastic lock that releases it, then look for corroded or poor connections. Be careful not to force it or break the locking mechanism otherwise you will not be able to put it back together properly to keep good contact or stop water getting in.
Do you know of any wiring diagrams for my car ? so i know which colour does what ?
Wiring diagrams are in a thick book (Manual section 8 ) or on CD's as they are so complex that is what is needed. To work on these vehicles that is what you need I'm afraid.
