In California it is kind of a running joke that you don't really need windshield wipers – it never rains anyway. Well if you're not one living in a temperate climate and you're building, or driving, a daily driver, you will see rain, hail, dew, and probably frost. And you know best that those damp misty northern mornings sure are a great time for wipers.
As a reminder, I recently tried running without wipers and it sucked, so I called Mid Fifty F-100 Parts up and had Diane send me a kit with a brand-new motor and all. Once installed, I had no future problems with morning moisture on my windshield, and have enjoyed the reliability of the new components more than a few times since.
Now, as luck would have it, we have a 1955 Ford F-100 in the shop that is getting a complete wiper system and I was also installing a new motor and switch assembly in my new 1956, and Mid Fifty F-100 Parts came to the rescue again with everything we needed to update both trucks.
For the 1955, Diane sent over a complete system, motor, mount, arms, transmissions, wiper arms, blades, the works. For my 1956, I had her send me a new motor, mount plate, and switch. (I chose to use an intermittent delay switch connected to the new stock-style motor.)
The wiper assemblies for the 1953 to 1955s are mounted inside the cab, up under the dash. They use the wiper transmissions and the cowl-vent-handle bracket for mounting. The originals were 6-volt positive-ground, but these new reproductions are modern 12-volt negative-ground instead.
The 1956s are mounted on the firewall in the engine compartment. These were actually 12-volt negative-ground in 1956. The arms run inside the cab to the transmissions. All 1953 to 1956s use the same transmissions, nuts, and trim rings though. The 1956 nuts were actually slotted and require a special tool to install. The 1955 and earlier versions had the hex nut. (I always use the hex rather than the slotted nuts.)
This new intermittent switch option is really cool. The switch itself has the electronics to make the delay work. Simply wiring this switch to the stock-style reproduction motor gives you variable settings for the intermittent and two-speed fulltime operation. It even has the capability to activate a washer pump to squirt the window and then wipe the window three times. This is going to come in handy in the near future. Mid Fifty has a window washer setup that mimics the stock stuff. I'm going to install one and obviously use the switch. Follow along as I install a couple of wiper systems and an intermittent delay switch as well.
