Remove blower motor resistor and check to see if it discolored or melted. if so then replace blower motor resistor, also blower motor speeds 1-4 go through resistor, 5 goes direct from switch to blower motor. check wire harness connector at resistor, it should have six wires five power wires that corralate with the five settings on switch, so in each switch setting one wire should have power. the sixth wire is the ground. also harness connector to resistor it may be melted, if so go to dealer with vin number and get new harness connector with resistor.
I hope this helped.
