alright my new problem that i have had since the truck and im just deciding to do something about is my wiper switch. Alright so i have a 1983 chevy k10 and i need to know what the settings i guess is what you would call it that each movement of the switch does. such as far left, push in, 1 click right, 2 clicks right, and 3 clicks right. if anyone has what they each do would really help me out. And now for the issue that i am having, so when i hit the switch and any direction i comes on like it should but i doesnt shut off when i take it back to what i believe should be the neutral position. and when i go far left which i thought was just a single swipe it doesnt always shut off and sometimes also start up the bug wash. then the speed between 1 right and 2right dont seem to change much. would it be safe to say the issue is in the wiper switch itself or is something elso going on.
