Ford F-150 wipers won’t shut off

wipers won’t shut off. a 5 second delay then on.

AFAIK the 2021 models aren’t available yet so you either have a 2020 or possibly a 2012 model. If it’s a 2020 and assuming the wiper switch is in the “off” position, your bumper-to-bumper warranty should cover it. If the vehicle is out of warranty the switch may be bad.
