A4 cabriolet window switches

Dear All,
I had a problem with the drivers side switch. The one that does all the windows at once would not work trying to close the windows.
I took the switches out and gently removed them form the housing using a flat bladed screwdriver.
I cleaned the switches in an ultrasonic cleaner, which removed all the gunk around the contacts. Let it dry overnight and "hey presto" it all works.

Love that feeling! I've recently done the same with my mates Fabia vrs.
I had it in the garage for new rear calipers, discs and pads and a cv joint. The window annoyed me that much I had to fix it lol

I did the same with mine, I'm always pleased that Audi switches can generally be disassembled and aren't sealed units.

I don't have an ultrasonic cleaner though.. I've always wanted one but have never been sure how much I'd actually use it.

Another tip is use a pencil eraser to clean the copper contacts.

How easy do the switches come out to clean?
