Window lift motor replacement?

I only have experience with the later system used on the 412, but here the switches can also prove to be troublesome (as is the case on many other systems of the period). It is really worth taking them apart (watch for any springs and little ball-bearings!), cleaning them up with a contact cleaner (one of the glass-fibre pencils is also useful) and reassembling them — this always worked for me. The other problem on the 412 was that even the later type of motor got very wet and many of the connections suffered corrosion. After rectifying this along the same lines as the switches, I glued builders polythene inside the door to stop any water landing on the motors.

As I currently have an R-type (anyone want to buy it?!!) I have had quite a few dealings with them and they are a pretty helpful outfit.
