John,
I did the same thing on my 55 2nd. I took the vacuum motor down and
basically cleaned it up. It had a lot of hardened grease. I put some white
grease back in it and a few shots of WD-40. Replaced the vacuum hoses and
got a decent wipe after that. It would not do too much on an uphill climb,
but I could just let up on the gas for a second or two for it to wipe once,
then go again. Electric is the way to go!
During this time I tried that stuff that is supposed to help keep water and
bugs from sticking. Can't remember the name right this minute (gray hair
syndrome?) but it's in a yellow bottle. It actually worked so well I drove
several miles in a hard rain after my wiper went sailing off in rush hour
traffic.
Hope this helps,
Sonny
