I have a 52 Style line Deluxe. The car is equipped with the original windshield washer glass bottle with the vacuum pump inside. It appears to all be there but it won't pump water. I discovered there is a problem with the dash switch, although the wipers work, pressing the button to operate the pump doesn't put vacuum to the bottle. I can deal with that issue. I ran a vacuum line direct to the pump to test it, but it doesn't work with known vacuum. The question I have: Does someone rebuild or repair these units? Thanks for any tips, Ron
