It is under the hood, far passenger side of firewall. It is near the top, just above the wiring harness.
Diagram for location of blower motor resistor can be found herehttp://autorepair.about.com/library/images/bl441a-lib.htm
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.
check the blower motor resistor pack. should be firewall side of heater rectangular connector with 4 or 5 wires.
I have changed resistor a d blower motor still not working, maybe i missed a fuse or could the control switch not work?
most common problem is the blower resistor In the firewall on the passenger side of the truck is the blower motor speed resister coils, they burn out alot. I could not find one for my Dakota so I got one from a dodge caravan and I changed the wirring, that is the most likely problem
Inside the cab. Passenger side. Inspect the heater ducts Look for five wires going to the resistor. Should be two screws holding it in.
The Blower resistor should be tested which is located near the blower motor, the resistor is probably faulty.
It is under the hood in the passenger side firewall.
in the dash but check the resistor 1st the blow e.z. it is in engin comp. passinger side on heater core lines it looks just like a water heater fuse
Most likely a failed blower resistor.
Under the dash, far passenger side.
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.
