2004 Trailblazer AC vents?

[bugeyed]

I have been meaning to ask this for years. The left/driver center vent does not blow as hard as the right center vent. It's very annoying when I have a passenger 'cause they get more air than I do. It's just not fair!! So, has anyone else noticed this or do I have something blocking the flow in the center left vent?

I also notice the same issue with my 06 Envoy XL Denali that I bought from scrapyard.

Didn't get to tackle it yet as I'm still working on getting the brakes working.

That said, I will keep an eye on this thread for when the time comes!

Bump!

Any updates/inputs? I have the same issue

There are many posts on this issue. It could be a problem with the vent door mechanism, but probably the actuator has failed. Very common problem.

And the OP hasn't been here since that post.
