electrical and ignition 73 tii wiper pull switch

[Nader]

Any idea how to wire 73 tii wiper pull switch? I have three wires red/white/yellow and diagram that has these wires going to 53b/53a/53. But if you see pictures attached I have 53b/53e/53. I don't have a 53a and have 53e instead on switch. Are those the same?

Nader, these are basically resistors and not hooked up to any kind of ecu. Couldn't you just hook up the wire nominated for 53a in the diagram to 53e and test the movement? The easiest way is to use a multimeter and check the output. In easier term, you would have one cable coming in (positive) and two cables going out, each with different output. So test each with a multimeter using the ohm setting (20k). First find your main positive and connect it to the switch terminal using the diagram (presumably 53). Then use the multimeter and test the other two terminals on the switch by using the switch knob and connect your wires accordingly.

that makes sense. Ill try that approach. Thank you for your answer,

I was just dealing with this switch - black/red (SW/RT) should go to the input (53).  Yellow (SW/GE) goes to 53b.  White (SW/WS) goes to whatever's left.  it's a simple switch.  The resistors for speed are in the wiper motor itself. The switch just sends current to one or the other. Any 2 position switch would do (but not an on/off switch obviously).  Hopefully your insulators arent as cracked and brittle as mine.  Sorry in this pic the red and white wires are reversed (this is how my car was when i opened it up).

Thank you. I finally get the operation of the switch. I didn't realize the resistor was in motor not switch.  I appreciate the input. And my sleeves were broken as well. I did find black ones at dealer. Thanks again.

Thought I should mention - on my car, reversed wiring is the only way the switch works.  Wiring per the diagram makes high speed only work.  Perhaps it was defective and they just wired it that way at the factory.  Who knows.

wired mine this morning and it's working now. My understanding is that the letters don't mean anything. It's trial and error thing. Now i have the wiper on ALL the times. I have to figure out why that is considering i have a new stack switch on.

" Now i have the wiper on ALL the times. I have to figure out why that is considering i have a new stack switch on. "

The on off switch on the turn lever may be stuck in the on position or else you somehow have the washer pump on all the time which will also turn on the wiper motor.

I disconnect the pump and even removed the stack. Still when I turn on ignition the wiper motor turns on and stays on. My guess I have a bad relay. But I don't believe there is a way to test those. I took mine out of its sleeve and I see it making contact and staying on.

Nader, you need to go through the process of elimination. Grab a 12v bulb and hook it to a 12v battery using the viper switch. Do this outside of the car on your work bench. This will show you if your switch is faulty. If not, then you've got your viper motor wiring wrong. Bypass the internal wiring loom of the car and bench test your motor. A multimeter can do all this without the hassle of bench.

My '68 wipers started to run continuously. It was the motor itself, the park switch had become worn out. It actually was an easy fix after figuring it out. Bent the park switch contacts so they would no longer short out to the rotating part and it worked fine.

I once had the constantly running wipers problem and before I figured it out I added a toggle switch in line underneath my Dash then I found out about the park switch which was an easy fix.

I also have a toggle switch under my dash for the electric fuel pump

[Nader]

Do I have to take the wiper motor out to get to the park switch?

Also my car has a fuel pump toggle switch in trunk. Any idea why since you have same thing?
