Subject: '89 325i Window Switches
The contacts inside the window switches of my '89 325i are constantly
getting corroded and clogged with soot buildup. This causes the switches
to fail, usually preventing the window from being closed.
To avoid the cost of replacement, I have discovered that the switches are
easily disassembled with a small screwdriver. Once I have the switch
apart, I clean the contacts (a pencil eraser works well for this) and apply
a small amount of silicon grease to the contacts. The silicon helps
prevent corrosion and enhances the electrical properties. The switch can
then be snapped back together and re-installed in the console.
This is not a permanent solution, but it takes only a few minutes and saves
the cost of replacement. I have done this several times to my window
switches, and I figure I have saved $300. Hopefully, BMW has, or will,
find a permanent fix for this nuisance.
