i have searched, but have not found a problem quite like mine. my blower speed will not work on setting 3. no other speeds are having problems. i checked at the motor and i am not getting power to the blower while on that setting. i pulled the hvac controls and have some melting in the pigtail, but dont no what wire is the output for setting 3. im getting power out on several wires. from what i've read, the resistor only lets high speed work. so i dont know if that is the issue.
