amzn.to/31cDOY2 Replacement blower fan on Amazon.com
Just a quick video showing how easy it is to remove and clean or replace your blower fan for your heater or Air Conditioning. This is on a 2004 Chevy Silverado work truck 1500. I was able to remove the blower fan assembly with no tools. Cleaning it made a huge difference. Every time I turned on the air conditioning, it made a loud deep noise and vibration due to the imbalance of debris inside the fan. After cleaning the fan, it runs very smooth and quiet.
No tools needed for this job.
You might have noticed that the fan speeds 1 and 2 do not currently work in this truck. That is most likely caused by a bad blower fan resistor. I may be doing a video on that soon as well.
Thanks for watching!

Awesome, Dan, my AC and Heater wasn't working, fan made a terrible noise, had a pack-rat issue last year, got rid of the rat who was living in my firewall but didn't dawn on me to check the fan or know how to. This tutorial was perfect, took me 10mins, fan was FULL of bedding. cleaned it, replaced it, cleaned it again, now have AC and HEAT again. By the way I live in Tucson, AZ and the heat was killing me. 106° the past week. Thank you.

[@bigdogpitbull03]

Just fixed my Avalanche this way. Thank you.

[@Deputy276]

Just experienced the EXACT same sound/vibration on my 2004 Silverado. Glad to see the fan is an easy access. Like others, I hope it is just funk in the squirrel cage and not a bad motor. Thanks a ton for a VERY complete and precise video. Well done, sir!

[@DantheFixitMan]

Best of luck with it. Thanks for watching! Take care, -Dan the Fix it Man

I have a Chevy Avalanch 02/03 and the passenger side fan was making an awful noise. Your video pointed me right to the issue. I found a piece sound dampening foam had fallen.. Popped it out removed the foam hooked it back up and now its quiet again! great video. I didn't have to push the tab, just twisting mine released it.

[@Deputy276]

Just an update.... First off, the shroud that isn't shown in the video has three 7MM bolts on the underneath securing it on. The far right bolt (passenger side) was pretty easy to remove. The center bolt was a bit of a prick, because I think there was a "speeder nut" inside the shroud for some weird reason. I had to pull down on the shroud to stop the speeder nut from spinning while unscrewing the bolt. I finally got that out. When the center bolt is removed, you can pull down (carefully) on the shroud and start removing the blower motor. Now the fun part...that tab that has to be moved to allow the blower motor to be turned is all the way in the rear of the blower motor. I had to lay on the seats and almost stand on my head to get to it. I'm guessing the seats in the video aren't present, or it's a very small man working in the video. Also, the plastic tab was very stiff (15 years old so to be expected) and I had to jam a flathead screwdriver against the tab to bend it enough to clear. Finally, after wiggling the motor back and forth, it dropped down. And lo and behold, a dead mouse, along with about 30 large maggots was the culprit in my case. I got it all cleaned out and tried the motor and it was quiet as a...wait for it....DEAD MOUSE!!! :-D Putting it in only involved hassling with the dang foam insulation ring, but I finally got it all assembled.

That's disgusting, a week ago I tried replacing my cabin air filter and got to that last bitch of a 7mm bolt in the middle but couldn't get it out. Come to find out that my 07 Silverado classic doesn't even have a filter in it. I'm gonna remove my motor though and see what's up with it. Round 2 with that middle bolt.

[@Will97675]

I see what you mean about the center screw. It was a bitch to get out.

[@chancep2003]

This worked perfect for me, thanks! Best thing about these old trucks is how easy they are to work on. Don’t even gotta pull the dash just literally reach up and spin it out. It was just a little foil gum wrapper stuck in mine that was makin noise lol

[@loganmaximus2160]

Had this exact problem on 2004 Chevy Suburban Z71. The hardest part was getting the last screw out for the black plastic shroud that covered the parts. Pulling the fan out was just like your video. My fan had only a couple of leaves in it. Once they were out, I used the blower on the fan to make sure things were cleared out, ran it just like you did outside of it's home, and put it back in place. No more sound! Thank you! Now I can get full AC breeze in hot Texas. Now, I have to swap out the HVAC blend actuator, which also required taking that black shroud off. No way is that going back on until the actuator is swapped successfully. I will also be replacing the HVAC control panel because the numbers go the opposite direction of what I am trying to set and it's a pain.

[@jaygutierrez8725]

I just wanted to say that was the best and simplest explanation I’ve ever heard on here even it was simple fix some people make it a pain in the ass to even pay attention to .. so thank you

[@djbrad81]

This video was extremely helpful...I was getting loud noise and vibrating sound when on full blast...come to find out a bird made nest under hood and all the debris fell into fan. Had it taken off and cleaned up in 10 min. Thanks a bunch!

[@DantheFixitMan]

You’re welcome! Glad it helped you out. Take care, -Dan the Fix it Man

[@Dirtymax_Danimal]

Straight to the point and right down to the issue. Thank you. You da man!!!

[@trekmcdonald9608]

Very good video. My truck happened to have the extra plastic peice under the hvac system. Way harder to remove the plastic than it is to remove the fan. I had minimal noise compared to the video. To my surprise my noise was caused by a single medium/small sized dry leaf and that was it

[@robberthiaume5106]

Just watched this video and it just help me completely fix my issue in my 05 uplander. It was filled with crap inside the fan. Thanks man!!

[@DantheFixitMan]

Hi Rob, Glad to hear it helped you figure out your issue, Take care and thanks for watching! -Dan the Fix it Man

[@michellef7607]

Thank-you for showing how to unclip the damn thing, none of the other videos I watched showed that and I spent 1/2 hour squeezed in under the glove box trying to get it! 🙂

[@JacobDostres]

Thanks for the video!! Very helpful! Now I’m gonna clean mines today. That vibration had me worried.

[@WindnRain24]

Haha, that intro, thought snoop and dre were going to show me how to fix my truck :D :D

Nice clear video and sound. Fixed my loud humming noise when set at 4 and 5

[@ryanheatherington9636]

Worked like a champ!! Had a receipt in there!!

[@makeminefreedom]

I have a 2001 GMC Sierra 2500HD that is making the same exact noise. I will definitely be removing the blower fan and cleaning it. Thank you.

[@billyhill3226]

Worked like a charmp!!!!! Thank you for the video. Like others have mentioned removing the plastic cap was a pain in the arse lol

[@abrahamvelez6976]

You just saved me hundreds did it for my 2002 Chevy thank you so so much 💪🏽

[@JuanGarcia-lv7xd]

Perfect now I will get to work. Fan on my Silverado is making noises hopefully is just dirty!

[@DantheFixitMan]

Hope that solves it for you! Best of luck. -Dan the Fix it Man

[@shaffer4220]

Great video. I was wondering the same thing about how “freely” the motor should spin. Mine works just fine, I decided to check it while replacing the cabin filters and found the motor has some drag but most likely that is how it is supposed to be.

[@360.Fishing]

Thanks! Weirdly enough I had a pecan shell! My ac was so loud. Thank you for the video! Much appreciated! :)

[@Johnnynitro238]

Thanks man! Even tho I have a 2018 Tahoe this video helped me figure out my problem! 🙌🏼

[@chabat124]

Thanks for this video. My 2000 Silverado was super noisy the higher the fan speed, especially on max. There were two covers I had to take off. The big one was easy, two 7mm bolts. The mini-cover over the fan had foam in it for lower noise I am sure, two 5.5mm bolts. The back one took two beers to get on and off. My fan had leaves and leaf stems in the squirrel cage. Cleaned it out and my blower is quiet. Hardest part was the fan cover bolt in the back. Why does a work truck not have a cabin filter? Don't the workin' man deserve filtered air too?

[@DantheFixitMan]

Glad to hear you got it done!

[@gsimard4510]

I got a 2002 tahoe that does that 😲😲😲im going right now to check the fan ill keep you posted

[@gsimard4510]

It work!!!😃😃😃🙉🔫💩💩💩

Mine is shutting down the wires are getting hot will a bad motor cause that? Its been noisy until it started this i also took it out no trash in it

I love my 2004! Thanks for this. I’ve found yet another reason to hate squirrels & love KZbin. HA! Now to find a video about replacing the cabin headliner.

Thanks for sharing this really help me 👏👏👍

[@timothysimpson912]

you will need a 7mm socket to remove the cover if not a work truck. Cleaned mine twice.

[@biggtribes2780]

Mine is brand new i just replaced it but it’s still noisy. There’s no cover, do you think maybe it’s the cover missing?

[@welder9163]

It's amazing what can happen when you do some research!! Thanks Man. A shop probably would of charged a $150. Lol.

Can't wait to see what treasure i will find in my fan. 04 Tahoe.

My noise is almost a metal on metal noise under the hood. Not sure if it's the pump, or a loose bearing on a pull. Anyone else?

[@jeremythomson2253]

Thanks mate

[@CrivRex]

Is it the same for the 2000 Silverado 2500 non HD version?

[@DantheFixitMan]

It's probably in the same location, but sometimes there is a cover you need to take off for access. Best of luck to you. -Dan

Hi Grant, Sorry, for some reason it's not really loud in the video, but I tried to record the sound it was making. I am able to hear it on my computer, but you may have to turn your speakers up a little. Thanks, -Dan the Fix it Man
