Blower/Fan Quit

[NotAMechanic]

I have a 2008 Yaris sedan with just over 100,000 miles on it. The fan blower has quit. It did stop working once before but after it sat overnight, it started working again. Now it has stopped and it isn't coming back on. I've banged on the dash and glovebox and that hasn't fixed it. It will not work on any setting.

I'm wondering what is wrong. Is it the blower itself or could it be something else? I'm not around much right now so it may take a while for me to respond. My mother is ill & I'm having to take care of her.

Any ideas are much appreciated. TY!

The motor of one of the two radiator blower fans on my 2000 Accord died at around 175K, and had to be replaced. We first verified that it was getting power by attaching its power wire to the other fan - which spun up just fine with it.

This is whatever it is that makes the air blow inside the car. Would that be a radiator motor? I thought it was behind the glove box.

It under the dash alright where it's hard to get at to test and fix. I've owned cars where you can just open the hood and get at it rather easily but NOOOO! On the Yaris the entire dash has to be taken apart.

This ain't easy or cheap but it's got to be done unless you live where you don't need ac or heat or a defroster.

I'm afraid it means paying a mechanic.

The Yaris blower is fairly easy to change without removing anything more than the glove box. Three screws mount it to the bottom of its housing.

So do I need to change just the blower motor or are there other parts that should be changed, too?

First check the 40A HTR fuse, which is on the face of the under dash fuse panel.

There is also the blower resistor assembly, which is the rectangular metal piece mounted to the fan housing next to the fan. If it goes bad the fan will not run. It can be checked with a multimeter.

Finally, if those are both good, pull the fan and check it with the multimeter as well.

OK thanks. The fan didn't make any noises. It worked fine until I turned the car off and wouldn't come back on when I cranked it back up.

Double check the fuse. I've seen high amperage fuses fail without popping. Similar to filament style light bulb that's failed but if you wiggle it around it works again.

If not a fuse, a new blower would be the most prudent. But,

My son's blower quit 4 years ago. I took it out, fairly easy, like Scott said just 3 screws and wire clip. So I took it out and sprayed WD40 in to the bearings which is not the best lube but it knocked all the junk out and has been spinning ever since. Please note, if you try this. please clean as much residue as you can as not to start a fire. And above all don't do this with it plugged in (hot) as most spray lubes have a super flammable propellant and the oil itself can be flammable. :evil::evil:

If that blower motor is anything like my floor fan you want to make real sure it runs good at least once week or it will seize...
