I found the windows switches much easier to refurb than the defroster switch. I used a fiberglass scratch pen which allowed me to clean the contacts without much disassembly. I cleaned both switches and took pics in about 20 minutes.
These get funky because they lack real high current contacts and the brass center terminal becomes burned.
Tools used:
-Xacto knife
-Small flat blade screwdriver
-Fiberglass scratch pen
-Thick cardboard or a business card
-Naptha, WD40, or contact cleaner
Step 1:
Remove the switch cap
Cut the plastic rivets that hold the switch body halves together.

Step 2:
Pry the case halves apart but be sure to keep the switch parts held into the larger switch half. I held my thumb over the terminals while slowly working the case apart.

Step 3:
Remove the middle terminal and burnish the contact area with the scratch pen.
In this image you can see how discolored the contacts get.

Step 4:
Burnish the moving contacts with the scratch pen

Step 5:
Clean the lower and upper contacts with naptha and cardboard until black marks on the cardboard are no longer created. The uppers will probably not show much wear but will still probably be dirty.

Step 6:
Replace the middle terminal.

Step 7:
Reassemble the case and make sure the upper contact bar is captured by the case correctly. I used a spot of super glue where the rivet heads were cut off to keep the case locked together.
