Blower not working on 1 & 2

[kem]

Het 6ga had this problem for a little while now , my blower is only working on 3&4 and now that's its winter time now the heat sometimes can be over bearing. I recently changed the blower motor resistor and the problem is still there. I have no clue what else to do !!!! Lol help pleaseeee!!!!! THANKS IN ADVANCE

Pull the controls out and check the wires coming off the switch. If you have a Ohm meter, ohm out the A. Wires and B. the switch. Make sure you are getting good continuity on the speeds

I would say it's most likely the blower motor resistor, but since you replaced it I would check the blower motor itself, but it could be a defective resistor
