the heater/ac quit blowing all fuses are good and the blower work when wired straight to the batt. does anyone know where the relay is? I'm thinking its either that or the switch. any other ideals?

I don't think there is a relay, but the fuse for the heater blower motor is located inside of the power distribution center, the black box under the hood.

Are those the fuses you verified?? If you only looked at the fuses inside of the cab, check the PDC.

If the motor it self works when you give it direct power, then test for power right before the resistor with the fan switch on. If you have power before the resistor with the fan switch on then you know the resistor crapped out on you.
