As I recently shared
, I just got (back) a W114 280C, and it was really kept in amazing shape by our forum's own
for the last 28 years, so very little for me to do.
But wouldn't you know it, a week in and I lost the 'click' on my drivers front window switch. I remember this from the last time i had a 280C, those switches are brittle and cleverly designed, but possibly poorly manufactured.
Anway, as you know the whole 'box' is part of the mechanics of that switch so opening it up, you must be very careful with each part. Mini screwdriver to carefully prise the chromed plastic cover plate off (3 tabs on each side). Sure enough this is what I found there, boken pieces of one of the two column 'pegs' or legs that contain the springy bits... let's call them cylinders and pistons for sake of this posting . .. since i don't know what else to call them
Of course I will pluck some next time I'm at a wrecking yard, or spring for new ones if I see them anywhere online at a reasonable price, but til then, here's how I mcGyvere'd mine back into service.
FIRST I SWAPPED the bad switch in the drivers group with a good switch from the rear passenger drivers side switch. No one ever sits there anyway. So there's a good new one now up front for me to wear out.
But before just putting a broken cosmetic dummy switch back into the rear seat position, i decided to try to fix the cylinder part of the switch. My thought was this: use heat shrink (06.4 worked for me) to bolster up the missing half of that cylinder. True, it kind of gums up the spring and 'piston' in there and makes for a kind of mushy but firm feel, but guess what? it DOES work as opposed to simply not working. Put in the rear window slot, no one's gonna complain too.
So if this is a partial innovative simple fix that's better than nothing, I thought I'd share my little idea with you guys. It kind of rebuilds that cylinder ... at least i know it will never crack again even though it's a little mushier as a trade off.
Hope this helps someone out there now or in the future. Sharing Is Caring.
