39 Buick windshield wipers

I just bought a 1939 Buick special for wine tours in Oregon's wine country. The car is a ground up restoration with near perfect body , interior, and running gear. The previous owners kept in a heated shop for 30 years, and It's never seen the rain. Being in Oregon that's unheard of. I was told The car was only brought out for parades and car show's, so the wipers were never used.  My problem is that the wipers don't get enough vacuum to work properly. I pulled everything to make sure it was in working order, I cleaned and oiled them then reinstalled.  With the wiper blades and arms off it goes back and forth with no problem. With the blades on the resistance stops them from working. I'm guessing the pump is week or the dash valve is worn. How can I tell if one is bad, or could it be another problem? Thanks Dan

Have you put a vacuum gauge on the line at the point it goes into the wiper motor to see how much vacuum you have?  This would be the starting point.  If you have the correct vacuum the problem would be in the wiper motors.

1939 S40 did not have the auxiliary vac pump built into the fuel pump. Just off the manifold.

 

If not used for ~30 years the seals in vacuum motor mechanism are likely all gone:---> no power when needed

Are you associated with any one single winery, or looking to do multiple winery tours?

I live in the heart of Oregon's wine country.

 

For those interested, one would be hard pressed to visit every winery around here in a months' time.

There are state road signs everywhere directing you to wineries.

CHEERS !

There are quite a few wineries here in southern Oregon, too.
