ac only blows low air even when i turn it on high. do u think blow motor needs replacing or resistor needs replacing.

Bypass the switch and the resister pack and wire the motor directly to 12 volts and see if you get high speed. If you dont i would say it is the motor. Usually if the resisters are bad then all you have is high speed because it bypasses the resisters.
