I have a trouble with the heat in my vehicle, when i turn the vehicle on there is absolutely no air what so ever that passes through the vents even when turning the dials. I have taken the blower motor out and hooked it up to an independant power source and the blower motor is fine working condition. It seems that im not getting any power to the motor. Any help would be appreciated
 
Well have you checked the fuse?
Also you need to check the wires going to the switch. If there no power , then the fuse is blown or the wire coming from the fuse to the switch is defective.
 
if there is no power on the dark blue or dark blue/dark blue and yellow wire at the blower motor with the key in run, then you most likely have a faulty ignition switch. with the key in run, i would jiggle the key around inside the lock cylinder with the blower motor on high. and see if it works. the way these trucks are wired, the blower has 12v. on it at all times with the key on. the blower gets its power feed directly from the ignition switch. also you could take off the steering column shrouds and slightly move the ignition switch connector and the fan will probably start working. if you unplug the ignition switch, you will probably see signs of overheating at the blower power supply terminal (dark blue wire) if this is the case, replace the ignition switch.
