Front wipers do not work (not the pluse board)

2005 GMC Jimmy.

Cause of problem:
The wipers were frozen to the window. They were turned on and did not work. I would not saw they were severely covered in snow or frozen, so I was surprised they did not move.

The only way to get the wipers to work currently. Is turn the wipers on high and pull the power connector to the pulse board half way out and move until a connection moves the wipers. (jiggle the removed power connector)

While testing, I had them work for 30 seconds or so, and was able to go in the vehicle. The wipers only work on the high setting, they are on max or off.

To try and solve this, i took out the pulse board soldered it twice, it still worked. then I bought a new board, which acts exactly the same as the first one. No change or improvement. The new one is still in now.

What do you suggest I do or test next. Is the high setting only a separate problem? Thank you for any help!

Note:
2 or 3 years ago I added cruise control. So the wiper control switch on the steering wheel is out of used vehicle, but it worked for the last few years flawlessly, turn signals still work today.
