07 Yukon XL air barely blowing

[davidtweiler]

You have 6 actuators David. 4 up front, a Mode actuator, driver and passenger temperature control and the recirc or fresh air actuator. The former or the latter not working proper can bleed off air flow.

You ought to put a Tech-2 on it, look for internal BCM codes related to the issue and use it to manually control the various systems for diagnostics. It would have paid for itself already.

If you live near me we can hook up mine and have a look. There's a thread on here that might show a guy with a Tech-2 in your area.

Thank you for the information. I live in northwest Colorado. Not sure where you are located

Are you sure it wasn’t added? it’s an easy mod.

I had the same issue recently in thecopcar. The filter was full of dust.

I would think a filter would be noticed when replacing the evaporator

There are a few of us around the Denver metro area (although we would like to be somewhere else) with Tech 2s, if you ever get around this area.
