My ac blower motor isnt getting any power to it


You can make sure all the wiring to motor is in good shape and not disconnected....The motor has a relay,fuse ,and a blower motor resistor..This is normally the problem...However make sure the dash control is working...

2001 nissan maxima heater blower isnt blowing


Check the fuse for the blower motor. If its okay, check for power at the heater motor. If you have power, and no blow, the blower motor will need to be replaced.

Heater blower not working


The heater and a/c system have several components as the control switch, the relay, the blower resistor and then the blower. First, you will need to test power at the blower when this happens to see if the blower motor is receiving power or not to determine if this is a blower motor issue or a power supply issue to the motor first.

Hope helps; keep us updated about your advance.

2001 dodge caravan Ac comes on but will not blow ay any speed . I replaced blower motor resistor.


try tapping the bottom of the blower motor with the blower motor speed selector turned to high and the key on. If the blower motor starts working replace it.

Another thing you can try is unplugging the blower motor and supplying your own power and ground wires to the blower motor. It doesn't matter what pin on the blower motor you supply power or ground. It will work either way. If it doesn't than replace the blower motor. If it does you might have a bad control head.

You could also have a bad blower motor relay or blower motor fuse located in the underhood fuse block. There should be power at the dark blue wire at the blower motor with the key on and the fan speed set to any position.

here's a how to article I did on blower motor operation.
