Pontiac Repair: Heat Fan, blower motor resistor, hey bud

Question
I have a 1999 Pontiac Grand Am - The heater/AC Fan only works on the high setting

Answer
Hey Bud.

Easy question and an easy fix as well. You need a blower motor resistor. more than likely it has burnt out or is corroded. If it's burn out just replace it with a new one It's a delar only part and it will look different then the one you take out. The design has changed a few times. If it's corroded when you get the resistor tell the parts guy you want the seal for cowl to stop the water from goinng into the heater box. Good luck :)
