How v70/s70 window switches fail

My mechanic gave me the driver side window switch from eater v70 or s70 to
have a look at. I pried it open and this is what I found.

It appears the there is partial vacuum created inside the door panel and lot
of lint gets sucked into overly delicate switch mechanism. Intermittent
operation results. Contaminated contacts arc and overheat the delicate reed
which partially melts the plastic (orange) cam actuator. Not a pretty
picture.

How can wi aviod this?

 

Wow, that one is pretty dirty. I opened up mine a few months ago, and it
was pretty clean. Sadly, I lost a couple of the springs that were inside
the switch. So, any readers ever open theirs up, be very careful not to
lose any of the springs!
