Where are the blower motor fuses
I looked in a book on this, as I didn't actually go out and look into the fuse box, but it is a numbered fuse box, so it should be rather easy t locate. Look for fuse 23, it is a 30 AMP fuse that runs off the Blower motor resistot block. Als it shows Fuse 17, a 10 AMP fuse that must control the Manual temperature control head. Either way, look at them both. If nothing is amiss there, look to the Blower Motor Resistor. It is below the glove box inside the car. Remove the right lower ari duct to get at it. If the fuses are okay, check the connector for power. If you have power, then perhaps the resistor that pokes into the housing is faulty. If you take it out, you may see that it is burned out on one or more of the little coils inside. They're not too expensive to replace.
I haven't done this on this model, but if this is a temperature controlled module, there might not be a resistor in there- I'm not certain on the 300M, but it is worth a look. Advance says so- about 32 to 164 bucks for it. I'd imagine the 164 dollar version is for the automatic climate controller- It sure looks fancy... but you won't know exactly until it is out- and if it's not working right now, it is definitely worth the look. The old-fashioned version should look like it is burnt out, but I imagine the electronic fancy-shmancy one won't. It may have to be electronically tested for resistance.The book I have does not outline that.
Anyway, it should not be a huge job to investigate. but if you have power to the resistor, the issue could well be in there. Another note, however: Unplug the blower motor from its' harness as long as you are down there, and carefully run a 12 volt source to it. Make sure you ground the other end of your connection to the motor. so you have two wires, a + and a -. If the motor runs, then it is the resistor. if it does not run, then it is likely the motor. Double check everything before you go buying parts, and never "Just" replace parts without proper testing. You could spend alot of money and get nowhere fast. Let us know how this works for you, but be methodical. Fuses first. Then the power to the blower and the resistor, then the motor. Good luck!!
