My blower motor is not working

Hello,

There is a blower motor relay and fuse and the blower motor itself. Here is a guide on how to check and replace the blower motor. The MOSFET is the resistor

It is not on your car but you get the idea. It could be fuse as well, here is a guide for that as well.

Here are the blower motor and air conditioner wiring diagrams and fuse panel locations as well as the resistor location. Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Did you check the A/C freon pressure and does compressor clutch engages when A/C is turned on?

Try banging the blower otor housing and if the blower starts working, the fan motor is failing and requires replacement.

Have you check the fuses?

The blower motor is controlled by the HVAC control unit grounding the motor, you should have power on the red/white wire coming to the blower motor with the ignition switch in the on/run position all the time. Considering you say there is no power there, the two fuses to check are on this wiring diagram. First one is the air conditioner 10 amp fuse in the panel under the dash on the left end, the other fuse is the Blower Fusible Link 40 amp located in the E/R Junction block in the left front corner of the engine compartment, both of these fuses send power to the blower relay. You can see all this in the diagram. Once you get power to the blower motor you can ground the other side of it (yellow wire at the blower motor plug to make sure the motor itself runs).
I believe the resistor in this case only limits the current flow on the ground circuit, not voltage. But has the same effect, slowing or speeding up the fan motor. But the power on that Red/White wire is the concern at this point.

But also if one of these two fuse's is blown, you are going to want to figure out why it popped to begin with.

So you have no power going to the blower on the Red/White wire at the blower motor? Did you have to run a ground wire to the blower motor also or did you just run power to it and used the controls inside the car?

Look at two pf the pictures at this site

One brand shows it plugging into a connector (on two wires)

The other brand shows it plugging into the body of the motor.

It does plug in, in either scenario.

Return with good news!

Well the control unit uses the ground side of the blower motor to control it, so you may want to run power to it but keep the harness plugged into it, this will rule out the control unit, and it will just be a power supply that you have to deal with. The resistor is on the ground side of the circuit according to the wiring diagram. As you can see in this diagram if you have no power at that harness plug for the motor with the key on, then that's the issue, it should be coming straight from the relay. Try what I mentioned above, keep it plugged in and run power to that Red/White wire by back probing the connector and see if it will come on. The relay may have a bad ground or the power wire coming in could be open somewhere.

Is this Red/White wire running to the resistor?

It should only go straight to the relay according to the book, I am hoping this wiring diagram is not wrong.

It seems if you have no power on that wire, that's the issue and the control unit should be okay. Running power to it from the battery was a good way to check it.

Looks like you are going to have to copy and paste the whole link or look through the catalog like I did.
