FJ60 Blower Motor just quit working

[TLink FJ60]

Hi, I'm a new member on here, so this is my first post. I was driving along with the A/C on and fan switch on one of the higher settings. Suddenly, the fan quit. None of the fan speeds work. I removed the blower motor and applied 12Vs across the leads and it works just fine out of the vehicle. I removed the dash switch, but I'm confused about how to test it. Should I be looking at the blower relay? I don't know where it is.

I know there are a number of posts about blower motors, but most seem to be cases where the motor works on 1 or 2 speeds. Mine does not work at all.

there is a circuit breaker under the fuse box door. It is labeled as "heater". Use a paperclip or wire pushed into the hole to reset the breaker.

You can also search this forum for circuit breaker.

I'm having the same problem. Thanks for the tip! I'll try to reset the circuit breaker later tonight. I have been putting off fixing it cause I just figured it would mean a new blower motor, so it would be great if it is just a tripped circuit! Thanks again!

 

[TLink FJ60]

Wow! That worked. I feel kinda stupid now after taking the dash apart to get to the switch. One question. If it happened once, will it likely start a pattern of doing this?

This happened in my 60 last week. (an 87) there is another circuit breaker below the heater one that is un-used as it is for power windows or sunroof. You can use that one as well. If it keeps throwing, don't use the highest setting on the fan and it won't throw as easily (until you can track down why)

Good info, I didn't even know mine had a breaker there!

Thanks,

Guys,

that thing under the dash is a circuit breaker, yes, but it trips on heat, not current. That means every time it trips, your wire going to the blower got warm. That wire is tightly bundled with all the others under your dash. They got warm, too. Keep resetting it and you will crispify your wiring. I was too lazy to fix the problem and did exactly that. My cruiser died. I have yet to get it going again, 7 years later. Don't be me...

Hot as in internally hot (due to electricity)? or hot as a result of ambient temperature from heater ducting?

Hot internally, due to current. It is a bi-metallic switch, so one side expands more than the other when it gets hot. This breaks the electrical contact. It cams over center, so to speak, so you have to push it back using the little hole in the top. It will prevent a fire, but it won't keep wiring from breaking down due to thermal cycles. I guess it functions like a slow blow fuse, only re-settable

Thanks for the info. So if I wanted to avoid trouble down the road, what would be the most likely problems/scenario to address:

- Circuit Breaker is old and over sensitive, but no real problem?
- Blower is working too hard (perhaps its old or ducts have too much debris)?
- some issue with the wires like they're old or making contact with other heat producing things?
​

Thanks.

I would think that "blower motor is experiencing too much drag due to age and use" would be on that list as well.

 

[ashack2004]

I would have to agree with Trapper, when the blower motors get old they will pull more current due to bad binding, thermal break down, etc... When this happen the Blower Motor will pull more Current (amps) and cause things like this to happen, circuit breakers to pop, pop fuses, heat. I would do a resistance test on the Blower Motor and pull the spec on a OEM Toyota Blower Motor or check your Toyota repair Manaul and then compare. If the resistance is more than the Stock one then replace.

I had this happen to me once eight years ago, or so--I was driving through the nevada or arizona desert on the freeway with the blower on full speed. Luckily I brought my manual, and was able to reset the circuit breaker. It has never happened to be again. Just because it trips once, does not mean it will trip again, soon. But I agree that if it keeps happening you either need to replace the circuit breaker (that's what the manual say's to do) or correct the high current draw.

Can't find the CB

I must be blind, I cannot find the circuit breaker on my 60. Will someone please post a picture of what I am looking for. I don't have anything labeled heater that I can find.

 

[waxwrapped]

If it makes any difference, I have tube fuses, not the blade fuses.

Waxwrapped:

As far as I know, all FJ60's have the glass tube fuses, not blades.
And for a picture of the "FJ60 blower motor circuit breaker", I figured there had to be an image of this out there.
I put exactly that string into Google, and select "images" and got a lot of crap, but also a fine picture of the component. To see that picture without wading through all the other hits, go to:

A/C : CruiserParts.net, Toyota Landcruiser Parts

And look at the last item in the second row (AC/Heater Circuit Breaker).
Then go under your dash on the left side of the drivers side, and look up. One fo the lowest items will be the shiny bottom of that unit, with a small hole near one edge. Push a paper clip in there (you'll feel a slight click, usually) and it should be good again.

Mine went out a couple of times over the past few years, but generally with the blower on full tilt, A/C on full blast, and climbing an overloaded Cruiser over the Sierras, or in the Nevada desert at 100 to 110 degrees. So not surprising.

(Not an advert for cruiserparts, but they have an image of this item online already - seemed rude to steal their image and repost it.).

The blower motor is easy to dis-assemble clean and lube. Takes about 1/2 hour and will lower the current the motor draws. The only tricky part is getting the brushed pushed back so you can stuff the armiture back in.

Does any one have a picture of what this circuit breaker looks like for the 60's with glass tube fuses. I have only found a picture of what it looks like with the blade fuses and mine is not like that picture at all. For the life of me I cannot find this breaker mine is 1982 fj60 .

And clean the tubes as they have a bucket of sand and dust in them:

This is a picture from where the air gets sucked in, How many people have seen this ;p
Notice the state of the art cabin air pollen filter...

And while youre there clean up behind the inspection hole cover accesible from the engine,
Need compressed air and vacuum cleaner.

Id replace the brushes while your in there. Mike
