    I have the same problem with my toyota. I took it to the dealership and of course it didn’t make the noise when they looked at it. It doesn’t do it everytime I use the heat or A/C. I don’t understand why they just don’t go ahead and replace it…seems to me that they want the warranty to expire, that way they can get paid to fix the problem. If my warranty expires before they fix the problem..that they know will be the last toyota I ever buy again.

    I took my 2010 in today. It was driving me nuts. As I was driving there OFCOURSE it wasn’t making the I drove an extra 10 minutes until it started. When I got there I was waiting and I made the dude come listen to it in case it stopped before I was next in line. It is fixed under warranty and was free. I am hoping it doesn’t come back.

      Isn’t that how it always happens? The sounds lessens right when you get prepared to take it in. LOL.

      Hi there,

      I have a 2011 with 54,000 miles and were you past your warranty and they still replaced it for free? Just curious since I have the same issue and was wondering if I do it myself or if it’s free I will bring it in.

      Thank you!

        Hey Jeff,

        I only have 25,000 on mine. And I bought it at the end of 2010 so it was still covered since it wasn’t past 3 years. So my warranty was still good. I would call them and ask. When I took mine in the dude was like “yeah we get these all back in” so it is obviously a problem. Supposedly they put the “new and improved” motor in..however that could be total BS. I am not sure. It has been in a couple months and I haven’t heard anything.

    I have the same problem. My question is do you have the new TSB # that i can refer the delearship to when i drop my truck off? Thank you for all the information.

      Sadly I don’t have a copy of that TSB anymore. If you take the old TSB #’s I reference in the story, they should be able to pull it up.

    I have the squeaking fan. I just purchased a 2011 Tacoma with 18,500 miles. Do you know if the fan would be covered under the warranty?
