Audi A4 ''audi a4 drivers window wont work all others are working ok'' also the lights on the instruments on the door are not iluminated.

TRY UNLOCKING FROM PASSENGERS SIDE.IF OK CHECK CLUSTER LIGHT IF IT GOES ON WHEN U OPEN DRIVERS DOOR.IF NOT REPLACE DRIVERS DOOR LOCK.

If it is cold enough the mechanism could be frozen. If not the actuator is gone and will need to be replaced.

check main plug for door

my front drivers door window makes a clicking noise and will not go dowmin my audi a4 2003

A typical problem for the newer A4's. The rubber tube that goes from the body of the car to the door will flex enough to short the wires out. If you remove the rubber boot and slide it back you can inspect which wires shorted out. I am 99 percent sure this is your problem, I have seen this in 4 other a4's. Hope this helps!

no adjustment, if dim some ilumination bulbs could be blown.

If you've just had the instument changed then its probable that the connector has come loose and will have to be re-connected. It could also be that the instument has failed. Take it back to the mechanic who changed the old one. This assumes that the car drives ok and all the fluids are topped up and ok.

it is probably a bad solder joint.pull the cluster out and look at the printed circuit board with a lense.there is a bulb that lights up the display as well.

CHECK UNDER THE RUBBER BOOT,WERE THE DOOR HINGES ARE, AND CHECK FOR BROKEN OR CUT WIRING. IT IS A PROBLEM WITH THE AUDI A4

Folks, Just found my problem ...... There's a flexible conduit (corrugated rubber sleeve) between the driver's door and the door arch which contains the wiring loom for the drivers door central locking/door speaker/electric windows/mirrors etc....discovered when I slipped off the sleeve that 4 cables in the wiring loom had broken due to repeated flexing when drivers door was opened/closed over the years (2001 Audi A4). Resoldered broken wires and insulated same....now working better than ever again ...ie dashboard back lighting seems brighter than it had been for some time? Also drivers door loudspeaker is back in action again (hadn't noticed that it had gone).
It's kinda difficult to reseat the rubber sleeving correctly after the repair job...will probably use some silicone sealant on the sleeve to ensure that there is no water ingress to wiring loom afterwards. I'm not too impressed with Audi design people after that, should have used cable that has a better flexibility rating (esp on drivers door!).

Paul.
