Ok guys need a little help. I have the problem of the blower only running on the high setting in my 2006 F-150. I just replaced the switch and it did not work reading here it sounds like this is a common problem with Ford and the problem is called the "blower motor resistor" I would rather change this my self but have no idea where it is located on my truck. Can someone explain where this is located so I can change it.

Thanks,
