i dont know why my heat a/c only works on high speed what seems to be the problem?
Most likely your blower motor resistor is bad
You can usually find it either in the firewall or under the dash next to the fan.Large plug with 4 or 5 heavy gauge wires,unplug it remove two screws and put the new one in
check fuses for fan and the relay maybe toast/gotta get good check on the electric
if its only blowing on high it could be twi things either your switch is bad or the blower motor resistor is bad !
