1969 Wiper switch & electrical question

[Suregrip391]

Yesterday I went to test some electrical goodies on my dash as the car gets put back together. I turned on the wipers and they went down towards the engine instead of up on the windshield! Looks like the paint guy installed them 180~ off. So I pulled the arms and hooked up the battery, turned the wiper switch on and I watched the posts (where the wiper arms press on, move about 1/4 turn. I was hoping to get them (the posts) put back in the "park" position so that I can put the arms on correctly. Here's the problem, I turned the wiper switch off, and then back on again to double check the positioning but it will not work anymore, nothing moves? Does the switch have to be mounted in the dash in order to get a good "ground" ? Also (see pic attached) I noticed that one terminal on the back of the wiper switch does not have a wire lead to it, is this ok? If not, what goes here? and lastly....the wiper swich got warm near that bare terminal and the switch also makes a slight "click" noise about every 8-10 seconds. Even with the switch turned off (obviously when battery hooked up and key is still on the power). Im thinking this switch just needs a good ground to work?

Look at this diagram and see if this helps any. The windshield wiper switch is in the middle of the diagram.

The switch doesn't need to be grounded to work. All it does is make or break the B+ connections to the wiper motor. It does nothing to the ground circuit. The extra connection is possibly the connection for electric windshield washers. Your car may not have that option but the switch is universal so it allways has the connection. Sounds like your problem may be a bad wiper motor or the switch has burned up internally.

I thought that may have been the case. The extra terminal for the electric washer system. My car was/is originally electric but I see no "extra" wires that would go on the switch here. When I look at electrical diagrams, they all show 7 terminals for the 69 model year and this one has the "extra". Maybe I will try running a jumper wire to the washer pump from this terminal and see if it works. It currently does not......

Yeah there you go. I need to get one of those switches myself to hook up my electric washer system. My 68 switch doesn't have the extra terminal for the washer. Good luck getting it all working.
