Didn't think of pictures in time

The past few years Google has found for me the records of many helpful people who found a problem and documented them for the aid of others.

The driver's window switch in my V6 Saturn (the gas mileage of a V6 combined with the get-up-and-go of a 4-cylinder) failed, so that the window would roll down but not up. This is unacceptable in winter. The shop said it would be O($200) to repair it. I found a few step-by-step fix-its on-line; none concerning the model I had.

I popped the switch console out and fiddled with it, bought a dental-probe affair and disassembled the last bits of the switch, cleaned out the melted plastic and swapped switches and it works.

And, after snapping it all back in place, I realized that I had missed the chance for a public service. I forgot to take pictures.

Without pictures... I'll try anyway.

Fixing the power window switches in a Saturn V6 console.

A switch console pries out easily from its location between the front seats, and if you can't figure out how to get the cable unconnected yourself just push it back in and don't bother reading any further.

The switch console has two rocker switches (and a lock switch as well if it's the driver's side console). It is made of an electronics board sandwiched inside three snap-together plastic housings, each held to the next with 6 tabs. A thin flat screwdriver and a little twisting will detach the housings from each other. Pop off the "lock" switch tab and the rocker switch heads.

Standing up high on the electronics board are the business parts of the two rocker switches, each held on with 4 tabs that you cannot pry away without using something like a dental probe. I bought some probes (not sharp) and found the plastic quite soft. I was able to pry the upper part of the switch loose from the tabs on one side easily, after which it came off quickly. I've never seen switches quite like it--the bottom (soldered to the board) part held two channels each with a metal strip (3 contacts underneath it) and the upper part of the switch had two short stubs that pressed against these metal strips--except that one stub was melted and the corresponding strip was covered above and below with melted crud. I scraped the strip and the contacts under it clean using a tiny flathead screwdriver, replaced the bad upper switch with the identical one on the same console, and reassembled all the bits.

Figuring it out took the longest time, and cleaning it came second. Reassembly was about 3 minutes. Strictly speaking this isn't a fix but a hack that swaps a heavily used switch for a lightly used one. But the window works now.

It's one of the most wonderful things about the Internet that a search engine can lead you to fixes like this. But you're right, pix or even a YouTube upload would have been better!
