Where does the power from the blower motor come from?
The power for the blower motor comes straight from a 30 amp fuse that is hot in run. It is the fuse directly above the flasher. This black box contains relays. It’s located just behind the passenger side headlight and in front of the container for the air filter. Here’s the relay box without the lid on it.
What is the relay for a blower motor?
The large relay on the right is for the blower motor. The lid comes off by pushing in each end of the lid to release the clips. This is the relay that was in my Ranger. The rust on the terminals was keeping it from making connection.
Where is the resistor on a blower motor?
The resistor is located down on the heater box under the blower motor. It can be reached through the passenger side fender well and is held on with two screws. Here is the resistor mounted in the heater box. The screw on the left side of it has already been removed.
How can I tell if my blower motor is bad?
The motor should spin at its highest setting. If it does then you have a problem with the connection at the plug. If not, you have a bad motor. The blower gets it’s power from a relay. In the case of my 1996 Ranger the relay is behind the passenger side headlight. If there is no voltage and the fuses are good, check the relay.

What to do if your blower motor is not working?
Generally the wires going to the resistor are: Check the connections for the setting that’s not working. If the connections are good and the plug and or resistor terminals aren’t rusted then try replacing the resistor with a new one. For some reason it’s a dealer item and won’t be in stock at your local parts store.
