How much vacuum should I have at the wiper motor?
49 chevy 1-ton. It is a work in progress but it's getting close. 49 1 Ton Pics | | | | | Joined: Nov 2006 Posts: 324 Shop Shark | | Shop Shark Joined: Nov 2006 Posts: 324 | I had the same problem. I tried lubricating the windshield with a little water and rainex, it did help some. Rather than try to find a rebuilder for my vac/motor I decided to convert to electric on the cheap. Have a look just for fun. I posted my solution in the electrical forum. For me this was a dependable solution. | | | | | Joined: Jun 2011 Posts: 63 Shop Shark | | Shop Shark Joined: Jun 2011 Posts: 63 | Before you spend money on another wiper motor you might want to give this a try: remove both wiper transmission arms from under the dash, clean and lubricate the ends where the (outer) wiper arms are mounted.

It will almost throw the wiper blades off the arms, they move that fast. I had the two vacuum motors rebuilt years ago by the Wiper Man. I tried all the tricks and just could not get them to work very good.
