    Hello all, I have a 2006 Tacoma and very recently all the blower motor speeds stopped working. I am wondering if anyone else has had this problem? Unlike many of the other posts that I have read they atleast get high to work where mine stops working all together and then it will start again.

    Thanks for any advice

    the problem is with your blower motor resistor. Sometimes the wires are loose and you can wiggle them to get full operation. The resistor is located under the dash near the floor on the passenger side. Below is a picture.

    If that does not work you may need to replace the resistor. Here are instructions.

    Hi Darek, thank you, thank you, thank you, I pulled my blower motor the other day and cleaned everything up and I can not believe how hot it now blows. As I mentioned before it was an intermittent problem and it hasnt stopped working yet but if it does a resistor replacement will be in order. Once again thank you for the tip. I did fix my thermometer/compass. So glad to see an orange glow. The post here are really terrific.

    Does anyone know a site that I can buy a blower motor resitor online?

    Thanks

    If it doesn't work on high either it's not the resister.

    If she does not start up on high reach under and slap the bottom of the motor a few times.

    If she takes off replace the motor.
    Seen this like 3 times in the past 6 months.

    Thanks for this one! I have the problem of nothing at first, then replaced the resistor and pig tail. Then NOTHING until I slam the glove box a couple of times. I guess I am replacing the blower motor today. Everyone mentioned the symptoms of the resistor but not the motor. Thanks for helping with that symptom.

    On the resistor, look at where that brown wire comes into the plastic resistor wiring harness. I'll bet the wiring harness plastic is discolored from heat, and, if you look at the metal connector side of the wiring harness (use a flashlight) you'll probably see black heat damage on the small metal tube connector. Use a paperclip to scrape clean the metal connector, and tug a few times on the brown wire to make sure the wire is firmly connected to that clip. Common problem for the older potted resistors, haven't heard of many issues with the newer model circuit board resistor types. All this from my stealership mechanic and personal experience.

    This is an easy fix and can be done in a half hour. I had the same issue with my 2006 4 door Pre-Runner. I took a bit more time and took the whole motor apart but that probably isn't necessary. The fan motor sits behind the glove box.
    1. Grab a 6mm wrench (which isn't really a tight fit, but it gets the job done) and stick your head in the passenger compartment. Look up underneith the glovebox.
    2. Remove the 3 bolts that keep the fan motor in place. The fan motor should just drop right out.
    3. Disconnect the resistor and whatever that other line is. Make sure to check for signs of overheating, etc. It the contacts are covered in black soot, that's an indication of a poor connection. Clean them up with a wire brush or paper clip but if the plastic sheath is melted or damaged it may need to be replaced.
    4. Take the fan motor to your work station. On the bottom of the fan you'll find 4 small screws. Remove those.
    5. Underneath you'll find two more screws on the motor's stainless steel housing. Remove those too.
    6. Scrape/blow out any visible dust/debris.

    You now have 2 options. You can spray it down with a penetrating lubricant, reassemble and call it a day. It'll probably get the job done. Don't forget to clean the air filter though before you wrap the whole thing up.

    Or you can do like I did and dick around for another hour. If you want to do that and really get inside the thing, remove the plastic fan blades from the top using a screwdriver to pry it upwards (warning, I did break off one of the blades. Still works no problem though). This will let you pull the motor assembly out of the rest of the housing and clean the entire thing, inside and out. The motor works using magnets though and will take some force pull it out.

    I took all the parts, stuck them in the sink, doused them in Spray9 (a degreaser/solvent), washed with soap and water, dried everything off, then doused the motor (aka, everything metal) with a penetrating lubricant (i.e. WD40, but I used something a little better), and then finally reassembled.

    Don't forget to check your air filter! You can replace the whole thing or wash and reuse. Though most people probably just buy a new one.

    Old Thread Revival:

    When I searched this is the thread that pops up so I wanted to add my 2cents.

    I did the TSB on the chirping blower way back, so technically this is my second blower in the '11 Taco.


    My blower started to stop working for brief moments, I chalked it up to my son having long legs, big feet, and Toyota not protecting anything under the dash. Then it slowly and slowly got more intermittent, to the point it was more likely not working than working. So I decided it was time to get under there and check it out. The plug connection for the power to the motor had turned black, and with a wiggle that would make it work. I cleaned it out some and that worked for a short time but then it was back to needing the windows down in the summer.

    My friend, a mechanic, thinks the motor is drawing too many amps. He said it happens over time, I've never heard of this before, but he said he's seen it many times and when people tried just changing the plug they end up still replacing the motor and then the plug again.

    So, would this be the resistor that everyone is talking about causing my issue? Or is it the loose connections pictured in DDD's post?

    Thanks

    BUMP:

    The problem with mine seems different. If I wiggle the plug in the very top right of your image the fan works again for a short time. The only thing is the plug gets hot and it was turning black, so I un-plugged it again. Appears to be the power to the fan.

    That connector and the resistor connector are both known for getting burned terminals.


    That connector on the top right is here:

    Part number 90980-10916 Connector

    Part Number 82998-12380 Wire and terminal

    Not sold as a kit, sold as each. So you will need one of the plugs and two of the terminal and wires.

    Connector:

    Terminals:

    You may also have a burned resistor connector and may need these:

    Plug Number 82141-04M40
    Resistor Number 87138-04052

    Thanks for the reply man!

    So you're saying I do need a resistor, and then since the plug is burnt to obviously replace that too.

    I knew it was plug replacement time, but I couldn't tell from some of the posts here if it was a resistor issue or a blower motor issue.

    The resistor may or may not be defective. You could check it with a meter. From your symptoms I would say that the resistor is fine and you just have a loose connection.
