2003 Pontiac Grand-AM SE. The blower motor has 5 settings for heat/air in the cabin. The motor only works on settings 4 & 5. Any idea’s why it would only work on these setting, and possible fixes.

Your blower motor resistor has likely blown for the 1-3 settings. Replacing it should restore all fan speeds. You may want to have a shop check out the fan though. Sometimes resistors just fail. Sometimes they fail b/c the fan is drawing too many amps and blows them.
