The fire-risk blower motor resistor harness has been recalled in the Hummer H3 and owners will start receiving repairs once parts become available. Owners of the Pontiac Solstice and Saturn Sky should be able to use the updated parts as well but will have to pay out of pocket as General Motors has not recalled them at this time. The Chevrolet Colorado and GMC Canyon also use a similar design and pose a similar fire risk but are slightly different than the recalled part due to having one less blower speed.

Hummer owners will most likely wait a few months minimum for the updated parts to get to their dealers to perform their free recall repairs. Colorado and Canyon owners may be waiting much longer — if they are recalled at all. The only silver lining for the Colorado and Canyon is that they use a similar resistor to the Toyota Tacoma and share a connector. The Tacoma also suffered from blower motor resistor issues and received updated parts along with a Technical Service Bulletin in 2011.

The original resistors for the Colorado and Tacoma were produced by KRAH-RWI in Slovenia while the new Tacoma part is made by Denso in Japan. The updated part from Toyota features a better resistor style that runs cooler, but the important part is in the connector pins.

The pins on the new part are thicker and prevent the connector from losing contact, reducing the chance for arcing that’s been the cause of the fires. The mounting holes and sealing surface are exactly the same between the Colorado and the Tacoma parts and the resistance values are similar enough to work properly and allow all speeds to be operational.

The updated resistor is available as part number 87138-04052 from Toyota and other vendors for around $27, while the harness pigtail is part number 82141-04M40 and runs about $23 with shipping. The Toyota resistor can also use the original GM connector if it’s not damaged. Colorado owners started using the Toyota resistor around 2012 and have reported that it is successful in resolving their issues.

The best scenario is for GM to issue a recall and cover the repairs — but in the absence of that, the Toyota parts are well worth the $50 to give yourself some insurance against a fiery end for your truck. It is worth noting that if you’re unable to do the repair yourself you can expect to be charged for two hours of labor from a qualified shop to complete the repair, raising your total repair cost to around $250.

    Thanks for the tip: I’m guessing this is already common knowledge in Hollander’s parts interchange manuals, which are the single most important tool for any long term vehicle owner.

      I don’t think this one will make it into Hollander’s interchange due to the slightly different specs

        Bummer about the specs; so it’s like when a tube audio fan subs a 12Axx instead of a 6Nxx or similar to cool down an overheating circuit?

          Considering a !2Axx needs a 12 volt heater supply, and a 6Nxx needs a 6 volt supply, the 12Axx won’t heat up enough to work properly, so no it’s not the same thing. At all.

            Tell that to the radio which stopped burning up its EL84s when I swapped in a 12AX7 for a 6N1.

      This is the first time I’ve heard of such manuals.. thanks!

        To a low buck project car wrencher, they’re a godsend – and for the high turnover wrecking yards, they’re de rigeur to better coordinate inventories and assist those searching for those hard to find bits that help make sales and keep the customer’s ride rolling.

        I’m still somewhat annoyed GM stopped producing its interior dashboard lights for the ’96 Roadmaster as early as 12 years ago, especially since those lamps were originally produced in the tens of millions of units: it’s forced me to spend an extra half hour after picking up the necessary part in order to dig around in old B-bodies and pull out as many of the twist-lock lamps as possible towards keeping the dashboard lit. On the plus side, they always laugh at the counter and let me have those bits free of charge.

    If memory serves, that resistor is a real bear to get to on the Canyon. It’s hard to wedge a screwdriver between the dash and the floorboard to release it.

    Just looking at the upper picture and the Slovenia-made resistor reminds me of the old home-built radios of the 1920’s with all the hand-soldered connections everywhere. The resistor on the right looks somewhat more modern. KRAH probably uses an old Sovtek factory. Sovtek, by the way, makes damn good guitar amp tubes.

      It’s possible. I was born about 250 miles away from where the KRAH-RWI factory is and there are loads of old Communist-era factories in the area that are in ruins although some have been bought up and re-purposed for the production of something new.

    Why on earth would anybody want to replace a perfectly flaky Slovenian part with a Toyota part made in Japan?

    I think HVAC is just about the only system my father-in-law hasn’t had problems with in his Canyon.

      Like JB and Murilee too (I think?) I once owned an ’85 Civic S 1500 hatchback and one of the ONLY parts to fail was indeed the fan speed resistor. That car also seemed to eat CV boots but mine was lowered and driven hard so I don’t think that was all Honda’s fault.

      Today’s General Motors *Mark Of Excellence* and Chevrolet’s *Find New Roads (To Catch Fire On* is brought to you by the all new 2015 GMC Canyon; The All-New Canyon, if it spontaneously burns to a crispy shell, GM will blame you reflexively and deny warranty coverage:

      It’s an Eminence Front/A Put On and A Well Tailored Scam at GMC

    What is a real mystery to me is that we are still even using blower motor resistors at all now in 2015 – my 1988 Buick had a solid-state blower motor controller on it.

    And yes, I know, it’s because the resistor pack is the cheapest solution.

    But still . . .

    Thank you bean counters! Always a pleasure to know that all the electronics in. $30,000 vehicle were built by the lowest bidder.

    Like shaker said… “OMFG! These resistor parts are actually half the price of the Chinese ones! Order a million of them! It will save us 3/10 of one cent per truck!!!”

    Why the …. don’t they use PWM?

    My 1994 Citroen Xantia had no resistor and used a pair of transistors and PWM current limiting to control speed and a Relay for the top speed to bypass the transistors.

    Thanks for posting this – My cousin owns a Solstice, and I’ve sent him the links.
