I’m helping my grandson with his 2004 f-150 XLT. His wipers are not working. So far I have checked all the fuses and relays and the are all good. My question is, is there switch power at the multifunction wiper connector. And if there is what pin is it. So far none of the online wire diagrams have been helpful in figuring that out. I have checked power at that connector with a multimeter and do not get any voltage with key on or off and nothing when turn switch for wiper control is turned. Any help would be greatly appreciated.

Thank you
