A/C not working correctly

[Brok_dad]

I’m new to the forum, so I hope I’m posting this in the right place.

I have a 2006 base model coupe. I’m having an issue with the A/C. The air itself works great. It blows out nice and cold. A couple weeks ago I switched to defrost. When I went to switch it back to the vent, it sounds like something is blocking the air from coming out of the vents. When I turn it to vent, the air stops coming out of the defroster. I initially thought it might be the right side upper actuator, but it does switch from defrost to vent, so that’s not the issue. It just sounds like something is blocking the air flow. Has anyone else experienced this or have any idea what I should look at? Thanks in advance.

The blender door mod. is bad!! It's a very common problem, and is a pain in the A-- to change! However the blender door mod. is fairly cheap, the problem is taking your dash completely apart! "NOT" a novice job at all, if you are not a skilled mechanic, you might leave this job to a Pro?
