ok for your wipers i think its possibly a bad circuit board inside the wiper housing inside engine bay mounted to drivers side firewall. i replaced mine it was a known issue with the trucks and a recall , buy the new boards at orileys.

my issue was they would not come on , the new part did the fix, can also check the wiper relay.
