You can plug the new one in without installing it and see if it does the same thing. If it does you need to dig deeper. If not install it and keep it moving.

 

Thanks boss ... I'm going to just install it and check the grounds/circuits on the "black box"

 

The black box is notorious for acting up. You can put another black box on it, or attempt to resolder all of the joints on the circuit board. The circuit board is difficult to remove from the black box, but can be done with some effort. Position the sector disk correctly before reassembly.

 

Is there an image how the sector disk should be positioned...?

Thank you kindly....

 

My wipers freaked out a few years ago--turned out to be a frayed wire near the bottom of the steering column where the wiper and TS harnesses slide. When the wipers/washer stopped working a couple of weeks ago, I took off the panels and the plastic slider cover over the harness, and re-positioned the harnesses inside the white plastic slider to reduce friction. Didn't trace the failing wire this time, just re-arranged the harnesses a little, and now everything works fine.

 

Hey guys....

Quick update..... So, the wiper motor was swapped, "black box" seems fine and now, my wipers work ONLY on the fast setting and pause slightly when the wipers come down in the rest position before coming back up ... soooo damn frustrated and confused....and of course, its starting to rain!! Jeez

Is there another vehicle's unit that works with our vehicles, plug & play...?

 

All of the GM cars of the same period with variable wipers had the same black box. If it looks the same, it will work. I have removed them from the smaller Cadillacs, Pontiacs, and Oldsmobiles. They all worked.

 

Thanks Jim....

I just noticed that my rebuild wiper motors' contacts are straight blade ... and the OEM I took off.... the contacts are like yours...curved

I wonder if this could be causing my issue... (I'm going to up load a video)

 

Here's my OEM contacts on the wiper motor

And here's the aftermarkets.... notice the blades (in the white area) they just shoot straight up...

 

I keep a number of used ones on hand. I look for wipers that are correctly stored by the motor to find ones that work properly.

 

I'll be making a recon trip to the local wrecking/pick-a-part yard and look for one....
