HELP! Wiper switch problems....

[carnuck]

The switch is still available new (someone might find the link to the part number I posted a year or so ago) Napa number was WS something. It was for an '81 F150 pickup.

What about the delay unit, are they still available new? I believe that's where my problem lies.

I don't know if the delay units are available new.  I picked up some of the Ford units over the weekend to see if they work with the Eagle.  It appears that Ford changed the design of the wiper switches somewhere around 80-81.  Prior to that time they had 7 electrical posts, and I believe they would replace the AMC switch fine.  The ones I picked up were all mid-80s or sooner, and have only 6 electrical posts.  When you plug them into the AMC, they operate the wipers fine, but no windshield washers.  I'm going to keep playing with the wiring to see if I can get the Ford switch to operate everything.  I'll keep everyone posted.

I have an '81 F100 pickup wiper switch and box in my '81 Eagle wagon and it works (did the same with my '82 Spirit) Maybe the one you got has a bad push button?

Nope, I picked up 6 of them, tested 5 and the washer didn't work on any of them, which prompted me to start investigating .  There is definitely one less terminal on the later models.  I did some troubleshooting last night, and I think that by adding a terminal terminal back into the slot that still exists and a jumper wire it should work fine....stay tuned.  I'll try to post a picture showing the missing terminal.

Here is a picture of the AMC intermittent switch.  Notice the terminal with the green circle:



Here is the later model Ford intermittent wiper switch.  Its missing the terminal, but has a jumper on the switch to the missing terminal spot.  However, this results in no terminal at the downstream plug, where it plugs into the car wiring harness.  Therefore, no power to the washer.  I believe if I put a terminal into the downstream plug (the slot still exists), and jumper it to the wire that leads to terminal 2 (just like is done on the switch) everything will work fine.  Wish me luck!!

Then hook up a push button and wire it to that terminal. I always preferred mine to spray separately anyways.

That's another good option!
