Fan Blower Speed Too High on Low Setting?

Recommended Posts

Just sold my '15 2500HD and purchased an '18 1500, so I basically have the same truck. I noticed that the blower speed on low seems to be pushing air quite a bit more than my old truck did. Just wondering if anyone else has noticed this, or is this how it is supposed to be? My truck only has 16k miles.

Did you ever change your cabin air filter in your previous truck?

A restricted one will slow your airflow.

My fan runs faster if the defrost button is engaged.

Are any of the vents closed?

I did change my cabin filter on my old truck...didn't check to see if vents were closed though. I'll do that and report back.

I purchased a new 2018 GMC and I wondered the same thing.  The fan speed on the lowest setting seems to be more than any other vehicle I have ever owned before!  It's a little annoying because I wish there was one step lower on the fan speed!
