    My 2009 has had this problem for a couple of years. Now it never works at all except on hi speed. Going to tackle it this weekend.

    got the fan working again. The resistors checked ok. So I just sprayed contact cleaner in the socket contacts and plugged it back in. I'm sure it's a temporary fix. Dream/goal is to get rid of the resistor pack and 4 fan speeds and replace with a variable speed fan controller.

    There’s a lot of info on AC only working on the high setting, but are there any experiences with AC working on all settings EXCEPT hi?

    I assume this condition eliminates the resistor being the culprit, so what are other checks? I have a 2015.

    Look at all the connectors for the switch and down on the resistor and motor.

    Well...my switch has a burned pin, so I’ll be researching replacement. Thanks for the input.

    So here is my delimma. I went and purchased the "updated" resistor from Toyota. It came with a service wiring repair kit (connector) because of the connector issues I'm sure. Now I have no idea how to wire it back. The colors are wonky and if you look at the end of the new connector it is labeled 1,2,3,4 not A,B,C,D like the old one. I spent 55 minutes on hold with the dealership and they have no idea either. I am awaiting a response from their tech's tech...

    That's the wrong connector. That won't even plug onto the resistor.

    its the correct connector for the new "updated" resistor - I verified this with the VIN with Toyota

    I call BS on that. What's the part number on the resistor they sold you?

    I don't know what the deal is with that part number. There are 80 posts on TW with the part number that is listed in the Toyota TSB 87138-04052.

    The only post with that part number you referenced is your post. However, if you google search your number, it shows up as fitting Tacoma.

    Lots and lots of Tacos have been repaired with resistor 87138-04052 and pigtail
    $32 82141-04M40
    82141-04M40. They fit together and they work.

    What's also weird is that if you google the part number on that pigtail in your pic, it retails for over $2,000

    So I read all of those threads, and I know what your saying is true...however; that was not my question or what I needed help with.
    I finally got a wire diagram from Toyota. Turns out they are installing the 2018 version now because of all of the problems with the earlier version. If anyone needs the diagram and not a reiteration of the other parts numbers, let me know.
    Update: I am attaching the wiring diagram as I have been getting many requests for it.

    OK, so post the correct part numbers for the resistor and pigtail and which color harness wires go to which color pigtail wires. Obviously, the pigtail part number on the sticker in your pic is not correct.

    Also, if there is a TSB about this fix, post the TSB number.

    Just replaced my wiring harness (yes - one burnt spot) and the resistor. Easy Peasy with the parts from Dorman (Dorman - Techoice 973-582 Blower Motor Resistor Kit with Harness) via Amazon. Price was $21.68. Most difficult part is the back side screw of the resister holder. Will advise if this fix does not solve the problem for good.

    Yes. I can verify because I just replace mine. There is a 3rd redesigned blower resistor and a wire harness.

    Blower Resistor Pt.# 87138-04070
    Wire harness Pt# 82141-04Q80

    CudaRae? According to your diagram I did .....

    A3
    B4
    C2
    D1

    .........and it works but low and med low seems to have very little difference. Could just be me. At the moment, I'm happy. I live in Texas. Already getting warm!


    EDIT JUNE 4, 2019
    Ok.....I replaced both parts and must have something missed wired.

    I should have: Low, Med Low, Med High, High

    I have : Med Low, Med Low, Med High, High

    I'm sure I'll figure it out one day.

    Just got an 06 ....I have seen plenty of discussion on fans only working on high.
    Mine does not do anything on the low speed, but all other speeds work fine?
    Any ideas? Is it most likely the same problem?
