how do you repair this bad boy?
When I switch mine on, it stays stationary..
Once I get the blades moving, they go really slow, barely movin...
I shut them off they snap right into the off position...

Do a search on the Hemmings Motor News site for wiper motor repair. There are several rebuild shops that advertise regularly in Hemmings.

Mike, it sounds like you're not getting enough vaccuum. first thing that i would do would be to check the line for cracks or obstructions inside the line. Also check to make sure that your grommets are in good shape so that the transmission arm isn't in a bind.

I just put a brand new vacuum line on the motor...
no creacks or obstructions
when I drive I hear a psst... ever 30 seconds or so...

I believe the gaskets in your motor are made of leather. Use oil for leather like the kind you might use on a baseball glove. Remove your motor and put a few drops of oil in the vacuum holes, then work it back and forth. Unfortunately, these old vacuum motors never worked that well. Every time you climb a hill (or otherwise step on the gas) they'll come to a stop, let off the gas, and they go again! I replaced mine with electric.

The Best Glove Oil?

For nearly 100 years, baseball players have been oiling their gloves. The oil of choice was neatsfoot for many decades. Neatsfoot used to be the oil that came from boiling the leg bones of cows. Now it’s any old cow oil with additional ingredients to make it clear and light.

Neatsfoot was so popular, even librarians used it on leather-bound books. But they were in for a horrible surprise. After a few years alone on the shelf, that leather started to petrify and crumble. Now librarians use lanolin – a lighter oil derived from sheepskin. You should too.

You can get lanolin in Lexol products, right at your hardware store. Lanolin lubricates the leather like neatsfoot, but it doesn’t make it darker and it doesn’t make it heavy or harm it over the long term.

If you still prefer neatsfoot oil, which gives gloves a nice tacky feel, go easy with it. Or try Lexol nf, their neatsfoot/lanolin mixture.

Are you partial to petroleum jelly? Some glovers swear by it, others say it clogs the pores and collects dirt. Just remember: you oil a glove to help lubricate the leather fibers after a long season has robbed some of the oil that was put in at the tannery. You don’t use oil because a glove is “dry” – since leather absorbs all the moisture it needs from the air. Go easy on the oil, and don’t depend on it to break in a glove either. That takes good old-fashioned elbow grease.

I'll check it out...
I am trying to keep the vacuum motor, in colorado it does not rain that much, and I think it would be cooler with it...

oh yeah, I put rain x on the windshield as well...
