When I turn my wipers on sometimes they work other times they don't. Is it the multifunctional switch or the wiper rely? Any advice would be helpful.

Thanks

 

Had the same problem on my'91, it was working on and off until one day it just stopped. Changed the wiper motor and wipers worked fine till the day I sold the truck. You could still check the multi. switch and relay.
