2003 wipers stop sometimes in when used steady

[blazer2007]

The wipers will stop for a bit then go again when used alot like in a heavy rain or snow storm. It does in all modes of the wiper switch, delay or on steady. Do they have a relay that protects the fuse from blowing or protects the wiper motor ? Is the wiper motor going or is the relay going if it does have one or is it the wiper switch. I know nothing about newer vehicles, all my other trucks and cars are old school. Just wondering where to start . Is along shot but I thought I would ask, couldn,t find anything online
