If the 2002 is like the 2004...
Check the bottom passenger side.
Unclick and remove the (1/2"x1/2") connector to it.
Remove the two screws.
The resistor should fall out.
Hand tighten the screws back in place so you don't lose them.
The Blower resistor should be tested which is located near the blower motor, the resistor is probably faulty.
For the 1989 Dodge Ram, the heater blower motor resistor can be found on the passenger's side, on the bottom of the heater box. It is beside the blower motor.
Blower motor resistor assembly is located under dash board on passenger side.
Most likely the blower resistor has failed. It is located under the hood in the side of the heater box.
The heater blower motor resistor for a 1992 Dodge Dakota is typically located inside the passenger compartment, near the blower motor itself. It can usually be found on or near the passenger side of the firewall, often mounted to the HVAC housing. To access it, you may need to remove the glove compartment or other panels for better visibility and reach.
The heater blower motor resistor on a 1988 Dodge Dynasty is typically located under the dashboard on the passenger side of the vehicle. You may need to remove the lower dash panel to access it. The resistor is usually mounted to the heater box and connected to the blower motor with wiring harnesses. Always consult your vehicle’s service manual for specific instructions and safety precautions.
The heater resistor on a 2007 Dodge Nitro is typically located under the dashboard on the passenger side, near the blower motor. To access it, you may need to remove the lower dashboard panel. Once exposed, the resistor is usually mounted on the HVAC housing and can be identified by its electrical connector and multiple terminals.
I have changed resistor a d blower motor still not working, maybe i missed a fuse or could the control switch not work?
Most likely a failed blower resistor.
The resistor block or blower motor resistor is used to control the speed of the blower motor. That is how you get the lower speeds on your air conditioning or heater. The higher the resistance the lower the speed of the motor.
RIGHT BESIDE THE BLOWER MOTOR UNDER PASSENGER SIDE OF DASH
blower motor resistor is burned out
