my wipers dont work and after lubing and cleaning the vacuum wiper unit i'm looking at having the unit rebuilt professionally or buying an electrical unit.
i have never been in a car/truck where the vacuum powered wipers worked well but thats because all the units were old and worn out. how well do they work when they are in tip top shape?
i like the idea of keeping the vacuum wipers and the price of a rebuild oruying electrical is about he same.
would anyone care to shead some light or make any sugestions?
thank you

Take that with a grain of salt, I've read that the fuel pump booster will keep the wipers working during acceleration but not had the experience myself. It's just a fact of life that they'll never be as good as electric. I kept the vacuum wipers on my 38. I just think of them as the original delay wipers.

I'm leaning towards keeping it origional. how bad could they be? my truck is already slow, loud and handles poorly (compaired to a 2009) slow wipers just add to the character. | | | | | Joined: Mar 2007 Posts: 863 Shop Shark | | Shop Shark Joined: Mar 2007 Posts: 863 | put a vacuum resevoir (sp) in line to hold some vacuum under accel

Has a "47" stamped in the case, guessing that's the year it was installed. The wire was run from the switch (above the windshield to the R. of the wiper motor) through the original vacuum line, down to the light switch for power.
Thought that was kinda cute.
Anyway, knowing they put it there 6 years after the truck was born makes me mind less that it's not "original". And, works well, no matter engine speed.
