How easy or difficult is it to replace the turn signal/delayed wiper switch on an early 90s Chevy C1500 pickup? Or how can I fix the delayed wiper
portion of that switch? It sometimes doesn't go into delay mode, it just
stays on even when turned off or it doesn't turn on in any mode. What
can be done about it? Right now, a lot of Rain-X is looking good.

 

check for a cracked circuit board under the hood, about a $30.00 part, very common problem.

 

If its under the hood, where? Is it behind the plate on the wiper motor? If it isn't, its pretty bare bones otherwise.

 

id like to know more about this also. im having the same problem kinda.
