blower wire heats up which makes heat and air intermittent

While running my ac or heater it would become intermittent. Under the glove box, I moved a thick wire that was too hot to hold on to but it would ether start or stop the blower from working. Not sure if there was a recall on this item. I also have a "service air bag" light that stays on all the time while the truck is running. I love my truck but electrical issues are starting to drive me crazy!

The spade terminal end connectors on the pigtail look like they were made in china like everything else is these days. I took a pair of needle nose pliers and closed up the gap on the ends of the connectors so there was more metal to metal contact.
