My fan for the ac will only run in high speed Is it the switch or the resistor that needs to be replaced and where will I find the part in my car.

Usually, the high blower speed is the only one that doesn't go through the resistor, so I'd suspect the resistor. It may be in the ductwork, on the other side of an inspection plate with wires leading to it, on the firewall near the blower motor.
