Depends on the year. You could try the resistor first since it is the cheapest. If not that, then check the fuses, relays and wiring to the control head. Then lastly, change the motor.
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
the blower motor resistor should be behind the glove box. just unscrew the two screws and that should be it.
The blower motor resister is located just below the blower motor to the left attached to the housing.........
The blower motor resistor is located just above the blower motor under the hood. It should have an electrical connector plugged into it and some screws holding it in place.
The resistor is under the passenger dash just left of the blower motor
Held in by two screws in a housing just to the left of the blower motor housing.
The blower motor resister is located just to the left of the blower motor on the passengers side right below the blower motor return air tube.......
It is either the blower motor control switch or the blower motor resistor pack. More than likely it is the resistor pack. It must be replaced or just live with it until it fails completely.
The heater blower motor resistor should be above the vent, behind and just below the glove box. It should have a three prong connector.
The blower motor resistor location on a Chrysler 300M is on the passenger side of the vehicle. It is on the floorboard next to the inside firewall, just in front of where the passenger sits.
Need to replace the blower motor resistor which is located just under the passenger side dash. 2 bolts on either side will remove it. Cost of replacement resistor is about $20.
The blower motor relay is located behind the glove box compartment beside the blower motor resistor. When you remove the glove box compartment, just look to the left of the resistor and the relay is located directly beside it with a metal retaining frame holding both the resistor and the relay.
Blown fuse, bad motor, bad blower motor switch, or a defective Blower Motor Resistor Pack.
I do not know what vehicle you are referring to but I just replaced one on a 1996 Nissan Sentra because the only speed that was working on the blower motor was 'high'. Underneath the glove box was a couple of screws that came out and the new resistor was put in. Two screws and done......... Most blower motor resistors are located close to the blower motor.
On a 1998, it's on the blower motor itself. Good bet it's the same on the 1996. Open the glovebox, push the tabs on the sides so you can open it further. You can see the blower motor. The resistor is the thing the wires attach to. Unplug the connector, and the resistor comes right out with (I believe) just one screw.
If your blower is working on some speeds but not all, more than likely the problem is a defective Blower Motor Resistor Pack. The switch rarely goes bad. Just a thought.
Could have just overheated
On the B250 van the blower resistor is located behind the passenger glove box, remove the glove box shell and resistor is located just to the right side, you can't miss it.
Looking at the picture in my Haynes repair manual it looks like the blower motor resistor is in the engine compartment mounted just to the right of your blower motor when looking from the front of the Explorer - Helpfull
Check to see if you are getting power and ground to the blower motor - if so blower motor is bad. If no power possibly fan switch or selector switch Also check the blower motor resistor, found in heater plenum.
Disconnect the battery negative cable. !!!Power is still on when ignition switch off!!!I have Olds Intrigue 2000. Blower control resistor (Controller) located behind theblower motor. Very close to the firewall, and it is a pain in the neck to get there.Using 5.5 mm. socket remove the blower first. (3 screws are holding the blower)Using the same socket (5.5 mm) remove one visible screw which holds the resistor.You will have to loosen two other screws located between the resistor and firewall. You don't need to remove them completely, just loosen them! Resistor just slides outwhen they loose.---------------------------------------------------------------------------------------------------------Disconnect the battery negative cable.Remove the RH instrument panel insulator retainers. Adjust the carpet for access.Disconnect the courtesy lamp from the instrument panel insulator by turning 1/4 turn counterclockwise.Remove the RH instrument panel insulator.Disconnect the electrical connectors from the blower motor resistor.Disconnect the blower motor resistor electrical connector from the blower motor.Loosen, do not remove, both forward screws. The blower motor resistor opening is slotted as access is extremely limited.Remove the rearward screw.Remove the blower motor resistor.
just behind the blower motor under the passanger side dash is a plug that is the risistor. two screws hold it in place. just remove the two screws and pull out. xterraparts.com has themm for about $19. Xterraparts.com has pictures of the part and a diagram. In the diagram, the front arrow is pointing to the cabin not the front of the car. Follow the four blue and white wires from the blower motor to the blower motor resistor.
It is called "Blower Motor Resistor Pack". It will be located near the blower motor. Sometimes you just have to follow the wiring from the blower motor back to the pack to find it. May be located behind the glove box, side kick panel, or behind the dash.
Behind the right rear panel just under the blower motor itself. It has red and black wires that plug to the motor and to other clips that clip on it
