Blower motor officially not working

Hello all,

The blower motor in my '07 Yaris has stopped working completely. When it first stopped working, I could take the glove box out and start it spinning manually, and it would be fine until I turned the car off. Now it's kaput.

Might I need to replace the whole blower motor, or could it just be the relay? (I promise I did a big google/site search, but I didn't find exactly what I was looking for...) I'm not great at repairing cars, but I think I could do either one on my own...

Thanks for your help!

Start by checking the following:

1. 40A HTR Fuse (power feed for the blower motor)- It's one of the large ones in the middle of the under hood fuse panel.

2. 10 GAUGE Fuse (power feed for the HTR relay coil)- In the under dash fuse panel.

Well, the fuses look great. Any suggestions on what to check next?

Thanks again!

First, try pulling the larger connector (4 pin) from the bottom of the blower motor, then with the ignition on, put the blower up to the highest setting and see if it comes on.

Second, with that reconnected, remove the small storage cup to the lower left of the steering column, turn the ignition on, stick your ear by the fuse panel, and listen for the HTR relay to click when you turn the blower switch from off to on an back to off.

Also, do you have a multimeter? The next step after this would be to start taking some voltage measurements to see where the power feed stops.

Assuming the blower motor has brushes, maybe they're burnt.

Pin connector on bottom of blower motor

I worked on a 2007 Yaris this afternoon. It only has a two wire connector on the bottom of the blower motor, not a 4 pin connector. I had no power to the blue wire or the black wire with the key on. All the fuses under the hood Ohmed out good.

The other connector, which is the blower resistor (for the speed control) has four pins. The blower resistor has a built in fuse, which is why I suggested to the O.P. above to pull the connector from it and put the fan on its highest setting, which bypassed the resistor.

Did you check the fuses that I mentioned above? One of the two is under the dash, not under the hood.

CTscott. Followed your advice. Removed 4 pin and blower worked briefly on highest setting before stopping. Guessing I need to replace my blower resistor then? Any advice on how to reach that panel behind the dash? You have been so helpful thanks! 07 Yaris.

Also, since it only worked briefly when I bypassed the resistor, did I blow another fuse?

Thanks again

I actually replaced the resistor and when I turned the ignition and blower on, it did the same thing. Motor Whirled around for a few seconds then stopped. Any new suggestions? Could use the help. Thanks!
