My girlfriend has an 07 explorer and the blower motor went crazy, staying on all the time, even when the key was off. Well then a few days later the blower just stopped, and now wont turn on. well i tested the blower plug from control to blower and no voltage comes through period. I havent got a chance to tes the blower yet but im sure its good. the truck is almost new. i read a blower motor switch or relay could be bad and if anyone could help find some literature on where to find the relay or switch it would be helpful. thanks.
