just recently i have been having a problem with my winshield wipers... if you turn the wipers on by any means i mean fast slow or single wipe or wash they stay on and will not turn off until the switch is turned to off and the car is turned off and restarted... what gives this is very annoying when it just mists or drizzles

This is probably better posted in the electronics section. If I had to guess though, the pulse module is messed up. That's what's going on with mine.

I believe it's called a pulse module, and I also believe that the only way to get one nowadays is to replace the entire wiper motor. Look on eBay or even from Rock Auto. eBay will, more than likely, have a few motors available, but they're used. Rock Auto MAY have just the pulse module, but I wouldn't count on it, but either way, the parts will either be new or remanufactured. Take that as you will as some reman parts aren't worth even what you would pay for the cores...

RA does have pulse motors, but you'd have better luck getting a working used one.
