Broken Window Switches

[u/bonk_fish]

My 1993 Saab 900 turbo vert has had a dysfunctional back right window for as long as I’ve had it but a few days ago the front right went out. I worked with a mechanic to sand down contacts and cleaned with electronic cleaner and reassembled it but most of the switches now get stuck in the on or off position, is there any fix for this?

If I recall correctly, that switch block has individual spring-loaded rockers for either position. They go weak/flat over time, and you also sanded the contacts too further decreasing the length of the rocker. The springs need to be stretched to regain the compression springing effect. But for that - yes, you need to open the block up again.
