1941 ford sedan vacum wiper motor and control
my 1941 ford super deluxe wiper only functions when I turn the control back and forth. There are three hoses one from manifold to switch and two from switch to vacum motor, Any advise is much appreciated.

Re: 1941 ford sedan vacum wiper motor and control
Sounds like your wiper motor may need lubricated as least. I used ATF and a syringe to get the ATF in to the wiper motor (via the Vacuum feed line) by moving the blades back and forth with the switch in the on position. This worked great on my '41 Coupe. Failing this, you may need to get your wiper motor rebuilt.

Don't put anything in your Trico that you wouldn't put in your engine.

Marvel Mystery Oil also will lubricate the wiper motor.

Re: 1941 ford sedan vacum wiper motor and control
It may have a problem with the valve as well. I think Ford only used that set up for the one year and then they went back to a linkage that pulled the valve on the wiper motor but I don't know for certain how long they used it. Make sure there are no rubber tube leaks and test the valve if you can. It seems like they had two larger tubes and one small one.

Re: 1941 ford sedan vacum wiper motor and control
When I forced Marvel Mystery oil into the vacuum line from under the hood using a syringe, I had a puddle of oil on my interior floor, hose was cracked under the dash. If those hoses are original you may want to replace them first.

Re: 1941 ford sedan vacum wiper motor and control
Unless you are going for an all original car, install a 2 speed electric. After buying a NOS Trico motor and still not having a good wiper system, I replaced mine with one from Mac's works great and fit like original, no revisions. BTW I have a NOS Trico that I would part with PM me.Al

If I remember correctly smaller hose will keep the wipers in the park position. so when the wiper switch is off there will be vac to hold the wipers down otherwise they would move all over, from the air across the windshield.
