I recently completed a rebuild of my a/c system that had missing components when I bought the truck. When the air was on, I noticed a loud humming noise coming from the blower motor relay. I got a new one and it did fine for a couple of days and then it started doing it too. Does anybody know if this is common and if it is caused by something other than the relay?
