    When I first start my 05 tacoma 4 cylinder and my engine is reving at higher rpms, the fan will make a grinding noise when I first engage the fan for heat or a/c. After the intial grinding noise, the fan runs fine and also after my truck runs for awhile, I can turn the fan on and off with no problem. It only grinds when my engine is first started after sitting for several hours and the engine is reving while in park. Thanks in advance for any help!

    Have you checked in the radiator shroud to see if anything is stuck in it
    ?

    Chris, thanks for the suggestion but Im not sure how to do that. I will give it a shot if you can give me alittle info. I reported the noise to the Toyota dealership but I could not recreate the noise b/c after I drive to the dealership, it no longer makes the noise. Shortly after, I had to replace the clutch (luckily it was under warranty). So they have looked it over and replaced some parts but it still makes the noise. So I guess Im going to leave it with them until they can recreate it but I was hoping to have some info to speed the process along...or in a perfect world, I could fix it myself and avoid taking it to them all together.

    If its the engine fan, open the hood, and tward the front, you will see it. There will be a plastic shroud arround it. Look inside to see if there is any debris around or in it. DO NOT DO THIS WITH THE ENGINE RUNNING. Keep the engine off and check it.

    If the fan clutch has been replaced, then maybe the fan itself is hitting the shroud? Look for damage to the plastic shroud or on the tips of the blade. Just an idea. Good luck.

    nothing in the shroud or no marks on the fan. its weird that it only does it when the engine is reved and makes me wonder what the connection could be. thanks for the help, all suggestions are apprectiated!

    Most engines when they are revved up will move a bit. You may need another person to rev the engine while you look under the hood for the noise.

    I have this same problem too when I first start my vehicle and have the AC already on when it starts. It's defenantly hit or miss with it though. Probably happens maybe <10% of starts. Mine is an 06 and I noticed it within 3 or 4 months of getting it new. I could never recreate the noise, but I have associated it with the AC being turned on at or near starting the engine while it's trying to stabilize. I have a 4cyl if that means anything.

    I have a similar problem. Right now when I have my heat going, there is a bit of a clicking sound only when I have it on the lowest and mid setting. If I crank her it goes away.

    this!

    when I first turn my AC on after starting my truck sometimes it makes a horrible sound. Then I'm like WTF, turn it off and on but it doesn't do it again.
