The HVAC control module or the replacement parts could be defective.

I just picked up an 02 Jeep Liberty. The blower fan wasn't working so I took a look. Found the power plug to the blower unplugged. Plugged it in and still blower didn't work.

The control provides ground to the motor through the resistor, so you cannot connect the negative blower terminal to ground-it has to go to the resistor. Put it back that way and let us know if there are still issues.

I have a1994 toyota pickup and i am trying to replace the blower motor for the AC but the new motor will not come on and I have replaced the relay and checked the fuses . what else could be wrong

Do you have power to the motor and is the ground circuit working? Most systems have a resistor which is what varies the speed of the motor. Get a volt meter and check power and ground first. Then pull the resistor and check for power to and thru thew resistor.

Check your fuse panel for a blown fuse

Blower Motor/Fuse

On Nissan vehicles, the blower motor gets power from the fuse box, and the resistor and fan speed control provide the ground circuit.
So you should be able to ground the motor and make it run if you have power going to it. Then you would need to check the resistor and fan switch. The high setting bypasses the resistor.

My heater and ac stop working

Locate the blower motor assembly. Unplug the electrical connection from the motor to the resistor. Check for power and ground at the resistor connector with the power on and the controls on. Chances are you have a blown resistor. Check to see if you can jumper the blower motor using jumper wires and the car's battery. If it works, all is well. if not, replace the blower motor as well. All blower motors are single speed motors. it is the resistor that increases resistance to "create lower fan speeds".

Rear ac doesn't blow air

Power goes thru the rear blower relay, then the resistor and motor. The fan control switch provides the ground connection. I would check the rear blower relay if power is questioned at the blower motor.

Blower motor

I'm showing a blower relay and a resistor used on models with manual ac control.
The blower motor is grounded and the fan switch provides power thru the resistor. So you have a 40amp blower fuse that handles high thru the relay, then a 30amp HVAC fuse that powers the blower thru the fan switch.
Do you not have power from the resistor to the blower motor on the purple wire ?

Ac blower motor

Check fuse supplying fan is not blown,
Check blower control switch is operating OK,
Check relay controlling fan is operating OK,
Check variable speed resistor pack is not faulty (the resistor pack is usually located in the blower ducting, in the blower airflow),
Check blower motor ground connection is not missing.
