Cadillac Repair: 1991 Cadillac Seville Wiper Issue, 1991 cadillac seville, cadillac seville

Question
I have a 91 Cadiallac Seville where the wipers only go up part way and then return to the stopped position. It happened after trying to move snow from the windshiueld [I know. I know].

I changed out the wiper motor that included the park switch. I changed out the wiper control module. I changed out the switch. The linkage appears to be in working order and undamaged.

The wipers move about 2 inches and then come back to rest. They are not slipping. Any ideas?

Answer
This is going to require several pictures and diagnostic test procedures to fix.
