Heater/ac blower my heater/ac blower used to work only on the two highest settings. now it doesn't work at all

Check the connection under the glove compartment on the passengers side. If the passenger extends their leg they could probably hit the wire that controls it and not make a good connection. I've had the same problem and it's fixed it every time. I think it's a blue and black twisting wire.

My fan heater only works on the highest setting 6

Hi. This will be the result of a failed resistor switch. the switch controls the current level sent to the blower motor. Once replaced, the motor will operate at your desired rate. This switch is an integrated part of the AC/Heater control cluster, that is mounted in your dash. You will need to remove the trim, and cluster assembly to expose the damaged switch.

Sounds like the blower resistor module needs to be replaced. Could also be the switch.

The blower for the ac/heat only works on the highest setting. The 1,2,&3 settings don't work.

Sounds like the blower motor resister is bad, it regulates the speeds of the blower motor, it should be located somewear around the blower motor, 2 screws hold it in the heater box and it has a electrical plug to it.

The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.

HVAC Blower functions only at highest (4) switch setting

if the blower works on high then its not a fuse it could be the switch or the resistor that cuts back power for the lower settings

Usually when the blower loses speeds over time the problem is the blower motor sensor.luckily these are relatively cheap.
