Huge THANK YOU to member danmclaren for suggesting the contact cleaner. It worked! I took the **** off & worked some in around the shaft. Also took the back off the module and applied some from the rear. Good as new now. Couldn’t be more pleased. TG for this forum.

To be clear, you disassembled the unit, can gained access to the back of the encoder, and applied contact cleaner to the assembly?

I'm surprised that worked, but good deal! Most of the time when those encoders get like that it's because the contacts are simply worn down to nothing.
If the fix is short lived maybe take some pics of the encoder and see if there are any part #s on it. I'm not pulling my control module out for that but it would likely be a 15 minute job to replace once a replacement has been found.

I'd rather spend my money on a 20 year-old car with 200k miles on it than one of the same age with 20k miles. The latter will have sat in a garage most of those years with the occasional short trip. Hopefully to a mechanic to have the coolant flushed. Long story short, mileage isn't a reliable measure of wear and tear.

Car is also 20 years old. Mileage doesn't necessarily equate to use / wear and tear. Could've been driven 1-2 miles a day or week for the first dozen years of it's life, by some hormonal housewife who believed that ripping the temperature **** violently clockwise on a cold morning would make the engine come up to temperature faster.
