Yep.
There are many dozens of sophisticated mini computers with software to operate a modern car. In my 1985 El Camino there is a circuit board that runs the windshield wipers, and the delay and washer function. It all fits under the cover of the wiper motor.
It lives in the engine compartment, so a harsh environment. That board is just not available new even though it was used on literally millions of Chevys, GMC, Cadillac, Buick, and across dozens of models from Corvettes, and Grand Nationals. I managed to figure out the problem with mine, with some luck and get it all working. They were never designed to last 38 years and 382,000 miles, but mine does.The used ones I found on EBAY looked worse than mine, and there is no microprocessors or software involved.
Cars are designed to be disposable now. Just scrap them and buy a new one!
