Fan Not Spinning Up, Random Airbag Light
I have a 2007 Yaris Hatchback with about 130k miles. Just last night I was taking some friends home and I looked down at my dash and noticed my airbag light was on. A moment later I noticed that even though my fan switch was in the 2 position there was no air moving out of the vents. After I dropped my friends off I pulled over in a quiet place and started poking around. When the AC switch is turned on, and I turn the fan switch on, the AC light comes on, and I can feel/hear the compressor kicking on too. When I turn the fan switch on and off I hear a quiet clicking noise just to the left of my steering wheel that appears to be coming from the dash.
This morning I got up and went out to the car. I turned it on and the air bag light was off and the fan turned and moved air when I turned the switch. Within about 5 minutes the fan stopped working again, but the airbag light never did come back on. Could this be a faulty relay? I'm new to maintaining my own vehicles so be gentle :) Thanks! |

Does your fan work on the highest setting? If it does you need a blower motor resistor.

No, it doesn't work on any setting.

Did you check the fuse box just to make sure everything is connected well? It doesn't sound like a fuse issue but car electrical issues can be pretty weird guys sometimes.

Check the 40A HTR fuse (which is one of the larger ones on the face of the under dash fuse panel {behind the change cup})
The intermittent airbag light could be caused by a few things. The next time it comes on, you can try the procedure in this thread to see what diag code is: http://www.yarisworld.com/forums/sho...d=1#post557473

I'm having trouble finding these fuses? The manual doesn't mention where they are or how to get to them...
I took out what I assumed you meant by the "Change Cup", the little swinging drawer type thing just under the mirror and gauge light controls, and looked in there. I can't seem to find what's what in there, but I did find that's where the clicking sound is coming from. I felt around to see if I could feel a vibration from the click and it was coming from two weird little boxes, a blue one and a pink one right next to it.

Ok so I checked the 40A HTR fuse... it APPEARS to be ok. Honestly I'm not sure what I'm looking for though. I assumed if it were bad the would be an obvious break in the fuse right? Anyway I pulled it, inspected it, and put it back in. Should I try buying a new one just in case?

New development: I went ahead and took off the glove box to have a look at the fan. Just out of curiosity I took out the filter, turned the car on, and turned the fan switch on. Nothing happened, but then I gently poked the fan blade and the fan spun right up. I'm starting to think maybe the fan motor is dirty or wearing out? Any ideas? Thanks for all the help so far!

The fan assembly can be removed without taking off the dash. There are just three screws that hold it to the bottom of the airbox. You could try lubricating the motor.
