A/C fan speed slower after TSB update?

[Synergy26]

It's there a way to increase the HVAC fan speed? It seems like it would work much better if it moved the air faster.

Check the cabin filter, it might need to be changed.

Did you try "max ac" in the uconnect settings?

The filter is new and I have max A/C on it just doesn't blow that hard. My newer Yukon the air moves and it cools off much quicker. Blows the same temp air just faster. I think the fan speed slowed down after having the HVAC tsb done.

So I found out I was using a restrictive filter so I went went with k&n cabin filter and air flow is much better now.
