Hi Guys new to the scene, job number 1 the passenger window doesn't work up or down, door wont unlock/lock, door mirror not working, light behind internal door handle not working but the floodlight works.
I'm guessing from what I've read already its possible the door control unit/window switch is there any way of testing the regulator to see if that's OK?

With all those things down, it might be also worth a check that the door to body connector is fully engaged and is not full of water or corroded.

On mine when I had to free off a stuck door catch I noticed that the window switch white connector had a small bit of corrosion on one of the pins. This caused the symptoms you describe. Quick clean and all was ok.

I had that problem on my E30 325i, the plug on the loom near the hinges had corroded badly, causing the central locking to malfunction.

I'd go with themoog, had similar problem, lift the black plastic window/mirror switch out of the door handle, unplug everything spray some WD40 on pins and reconnect/ disconnect half a dozen times. See how that goes

Thanks guys for all your help so far, today I removed the panel and control unit checked that was voltage coming through the door connectors.
Rebuilt everything as time was running out, door now locks and unlocks, the window motor works but sounds crunchy so Im guessing the regulator is U/S
So slightly corroded pins maybe? or cycling the power to the control module would it reset??
