E39 530d: New Drivers Window Switch

Re: my post last week - 'Gotta have a teething problem - Drivers Windows Switch', the problem is now resolved, thanks to a whole new switch module. Well a used one, but advertised as "perfect condition" by nerijusnerka on eBay and it lives up to the hype thankfully, seeing as the unit was a little pricey @ £25 delivered, but not bank-breaking to have my driver's window back in action.

It's a piece of cake to get the old unit out and plug in the new one and as soon I tried the switch all functionality had returned - I tested each window and the child locks, all now working fine, so I'm glad my deduction was right and it's not the computer... I also noticed a chip on the edge of the broken unit where someone has obviously had a go at fixing it before, so it's nice to give the car a blemish-free interior again - I can't spot a single other mark in there!


1. Fold a cloth over the end of a flat-screwdriver and gently prize it down under the edge of the switch-panel. Lift the edge of the panel up with the screwdriver a few millimeters and continue around the panel until it is proud enough to be lifted out by hand.

2. Starting with the rear one, unplug the two slim upper clips from the panel by depressing the button in the centre until the latch can be lowered. Lowering the latch completely lifts the plug clear of its socket.

3. Slide a flat-screwdriver down the gap on the rear-face of the large lower clip and lever the base of the clip outwards about 1cm until the wiring-clip slides freely out of the socket.

4. Reverse the process to install the new switch-panel.
