A Dremel with a tiny wire wheel can work wonders on those, just be sure to wear eye protection, as those tiny bits of wire really fly!

Some electronic contact cleaner with an acid swabbing brush with the bristles cut to 1/4 inch long works great also.

Neat, not sure what year car you're dealing with but my '67 fuse block issue may be interesting?

Various circuits were having intermittent cut outs. Pressing on the fuses often healed the issue. I, also concerned about corrosion, discovered the brass clips that grip the fuse were clean but loose! Seems the clips are riveted to the rear block "bus bars" now loose making poor connections. I can't think of a good fix to tighten these mechanical rivet points? Soldering looks also sketchy. The plan is - all circuits will move over to an after-market block with blade fuses. Ugh, old -timey parts can be no fun and gotta go.

I would think that you could solder the small rivet joint successfully if you can get it clean. Media blasting should do the trick.

^ I spotted another of the posters threads and it's an 80's car which wouldn't have the rivet issue.

In my case, all cleaning and soldering would have to be performed on the block where it's hardwired under the dash. Tricky but maybe doable? I'm chucking the block to get newer fuses and gain spare taps. Some of the small sizes of the glass style are getting hard to find. Standard length and mini-standard are still out there but my block has two or more odd sized buggers I've never seen.

I don't think the fuse block is hardwired, just a PITA to unhook all of the wires (and then put them all back where they belong........

wiper motor works it is just a bad switch. man that wiper is a pain to get out,i might have to get it out again when i took it out last time i took the cover off and a piece of plastic fell out i think it was part of the park switch i guess it is off to pull and save for parts.

There's an adjustment for that (or sometimes the park piece that fits into the nylon gear is just gummed up).

You need to read the entire section on the 2-speed depressed-park wipers in the FBM (or the CSM in earlier years) and go through its checking procedure - its complicated but manageable.

Hmmmmm...

When you read the section, you will see what those parts are, and whether it can be fixed, but it sounds to me like a new wiper motor is in order.

There are many variations in wiper motor and attached pump.

Depending on your skill set, you may be much better off cleaning and fixing what you have, which fits right in every way. I could have done that on the '66 442- it had dirt and broken wire- in about 3 hrs. But, Noooooooo, the owner buys a "new" one. Pump doesn't fit, wiring differs.... three DAYS to work out all the bugs for one that ain't even correct. *sigh*
