Hello,

Thank you for reading this post. Windshield wipers will not turn off. I replaced the swith with a new one.

Thanks Andy Wilcox 1963 Roadster

Andy, did this just start after the new switch was installed? Did you do any work on the wiper motor assembly or even have the cover off? Need to know what work was done and previous electrical/mechanical history on wipers.

If your trying to just stop this wiper set from moving disconnect the wires to the switch and using electical tape cover the connections so you can avoid a possible short from a hot wire grounding out. Wish I could help more but need more info.Good luck,grr#33570

George,

Thanks for the reply. I will try and answer your questions. They first started failing only when it would rain hard. I thought it was the switch and replaced it. I have not done any work to the wipers. I did make up a manual over-ride by making up a wire with crimp-on connectors and heat shrink so I can connect them when I need to. Is there any other information I can provide?

Thanks Andy

Common midyear problem

This happened years ago on my '63. Sometimes they would shut off, and sometimes they would continue for a while and then shut off. Turns out nothing was "broken". The wiper tranmission is a rather interesting piece of mechanical engineering. The transmission contains cams, pawls, and springs and depends on some lubrication to function properly.

After cleaning all the parts and reassembling everthing properly with fresh grease it functioned perfectly. You'll need the '63 shop manual for sure to do this job. It has a thorough section on the wiper transmission.

Andy, pull the metal plate that faces the distributor off and clean up the contacts and springs if possible. Make sure the springs are attached and nothing comes rolling off or out when you remove the cover plate.Watch the action of the parts when the wipers are running so you can get a better idea of the operations of the springs and contactors etc.

Insert a small non-conductive piece of material(spark plug box paper) between the set of closed contacts and see if that stops the wipers.At the same time look at the condition of the contacts, you may have a welded or pitted set.

For some reason you have a complete circuit and it's doing what it is suppose to do when you actually use the wipers. You changed the switch and no change. So what you want to do is open the circuit at the motor area mentioned and find out what is keeping the circuit closed.Good luck,grr#33570
