How to Fix a Noisy Blower Fan – 2004 Chevrolet Silverado – DIY

Please click the above link if you need to purchase a replacement blower fan on

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!
