The heater/AC blower motor only works on high speed. Until a week ago the first two speeds did not work either. Is there a relay somewhere causing the problem or something else. I can find no blown fuses. If it is a relay, can you tell me where to find it?
Thanks for your help

Check the blower motor resistor assembly on HVAC module near blower motor

Not to sound stupid but the resister is located by the blower motor under hood or under the dash?
Thanks for a quick response.

It say by the blower motor-be advised that other components can cause your problem such as the HVAC control module-Good Luck
