weird wiper behaviour
my winsgield wipers do some weird things. doesnt matter if its fast or slow speed. Sometimes they will run forever no issue, sometimes they get stuck, then after a minute they will resume normal operation. Sometimes i joggle the switch from off to slow, sometimes that gets em going sometimes not. Any ideas?

Sounds like you may need a new wiper switch/turn signal.
*edit*
Just realized you have a 91, my apologies.
I would try checking at the motor for loose or damaged wires. But your saying if you play with the **** it works. Well I would grab a spare switch and try it out.

Loose magnets inside the wiper motor would do what you described. I went through 3 motors before finding what was going on.
Over the years the glue will degrade holding the magnets in place. They will move around slowing down the wipers then stopping. Sometimes messing with the switch will cause the motor to rotate enough so the magents get back in proper timing for the armiture.
I cleaned out the motor case and re-epoxied the magents back in place. The 1st motor I didn't get the magnets in proper place and it would not run. The 2nd and 3rd motors are working to this day!
