Fan speed settings 1, and 5 didnt work. to fix it all you have to do is replace the blower resistor motor. just get the part from autozone and go under the dash and get a 7mm ratchet and take bots off the plastic piece under the dash and isconnect the connectors and get the new resistor and plug it back in
