    First off hello everyone it's been awhile. I've been a busy boy, but i'm back now.

    Anyway on to my issue. This morning (4 am ) I was heading to work and turn the air on and nothing came out. So I turn the dial up to the next notch and nothing and then the next and nothing. But when I put it on high it works and blows ice cold. So I'm kinda playing with it while eating a breakfast burrito, drinking scorching hot coffee, and driving like a bat out of hell and I still get nothing. It works fine on high, but not on low or in the middle. I here the A/C come on, but nothing. So basically I have no idea what to look at and to make this more dumb. When I got off today the damn thing works fine?

    Any ideas ?

    Check the condition of your cabin air filter.

    Sounds like you blew your blower motor resistor. It reduces the voltage going to the blower motor on all speeds other than high. High is full voltage, does not go through the resistor, and is not affected by a blown resistor.

    I have not had to change mine, if you look up the factory service manual on ttora, it should tell you where to look. They are usually located on the blower housing. Should be a pretty obvious failure once you get it out.

    Edit: I missed the part where it fixed itself! Its possible that the broken pieces of the resistor welded themselves back together. I have seen light bulbs do that.

    Get ready to replace the blower too. When blowers start to die, they draw more amps. They overheat the resistors without blowing fuses.
    Check the leads off the blower. Usually the connectors show some menting/blackening, especially when they finally fail.

    It can also happen when your cabin air system is restricted (full filter, mouse house, junk from running without filter).

    My '10 done the same thing about 3 months ago. It would only work on high. It is the resistor. Skytower is right, the blower motor is what causes the problem. I was fortunate, mine was still under warranty. They replaced the resistor 2 times, I was telling them the whole time that they should replace the fan motor as well because it make a chattering noise. So finally after 2 resistors, they replaced the fan motor AND resistor, and no problems since then-problem solved.
    Where is Alabama are you, I'm in Tallapoosa County about 30 miles northwest of Auburn.

    X2!! Mine went out about 2 months ago.. same thing,,works on HIGH but not low ad med. THen all of a sudden started working for like a week and half..but not now :( . Off to check the blower motor resistor!

    Well Guys.. $35 and about 10-15 min work and my blower motor is working perfectly!! Thanks and a rep to Joes06 :thumbsup:. Here are some pics for anyone else having problems with this.

    I initially removed the glovebox looking for the bm resistor..and found it was actually located "underneath" the glovebox. With a little help from Mr. 5.5mm socket i removed the 2 screws holding the resistor in it's housing. Then simply unclip the wiring harness and remove old resistor. Now you can either attach the wiring harness to the New resistor and then screw back in, or insert resistor and then the harness...it's a matter of preference. Now Test! :D

    Thanks for posting pics!

    Were you able to see anything wrong with the blower as Skytower had suggested?

    Its most likely a loose connector I have the exact same issue if it works intermittently then the resistor is fine. The resistor is either working or not it does not fail and work again.

    Next time it acts up put it in park turn the blower on a non working setting and wiggle the wire that connects to the blower motor. If it comes back on then those connectors are loose if not take some time one day and just wiggle a few wires if it does not come back on then look at the resistor block.

    Yeah threads w/out pics are pretty worthless :cool: I dont really have any probs with Noise, clicking or otherwise, and the fan seemed to move pretty freely so did not really check blower leads as Skytower mentioned..but did notice the Filter was full of junk..leaves etc.. May take a second look tomorrow in daylight.. and see if anything of concern. I guess if anyone has the time a quick service of the blower motor (clean and lube) may be worthwhile..my Taco has 103K so that may be a project at later date.

    I have a similar problem, I have just been too busy/lazy to check it out. My A/C started doing this last summer, all I have been doing is giving the blower a little smack and it works again. Only problem now is that even on high I have very little air coming out, as if it were on low.

    Bad connectors but the smack may have killed the blower motor.

    Haha ok well try checking the connector on the underside of the blower motor. It may have wiggled loose. My blower did act up then I unplugged the connector and plugged it back in turned it on to any setting other than hi and it worked. There is a bundle of wires further up from that connector if all else fails wiggle them not too hard but enough for them to move if it comes back on then you have either a loose connector upstream or an open wire(internally torn no contact between the wire strands).

    mine went out today also!!!!! I have no air what so ever! I checked the resistor and it has a little rust is there anyway to put a meter on it to see is it is good or not?
