No heat no ac blower not working took out blower motor checked it’s working replaced resister still nothing checked what I believe were all fuses dealing with heat blower motor they all looked good what should I do next 2007 Dodge Charger 2.7 liter

SOURCE: blower fan only works on high

If it is working at all then the relay and fuse is good and the problem is either the little vacuum hose on the back of the control switch panel or the panel itself.

chk the fan speed resistors mounted in the fan housing. You should be able to see the wires going into the box with 2 screws holding the resistors in place. Good Luck.

SOURCE: Blower motor on 96 Isuzu Rodeo does not blow on

if fuses are good, check for power at blower motor, when truck is running and a/c on. the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. if it has no power and the motor doesnt run, the motor is bad.

Check the Blower Motor Resistor. This controls the Blower Motor/Fan Speed.

SOURCE: we have a 2004 chryler

you may have to replace the reostat that operates blower fan speeds. check fuse first
