Stuck on defrost vent why?

Should there be two actuators on the drivers side? I have found one directly above the accelerator pedal, but after removing it and turning the door by hand it changed the air temperature on the drivers side.

Replaced actuator, found broken small vacuum line under hood and glove box, spliced and repaired. Air conditioner still blowing from defrost. I do not know where to go from here.

No leak at heater switch, it appears to be no leak under the hood. I need a better pic of what the vacuum motor looks like. Pulled the radio again & new Acuator is doing what it is supposed to be doing. Question! If blend door is opening when turn controls from hot/cold, will it be quiet? I'm to the point where I feel that I'm going to have to sell a grandchild to get it fixed. Air is blowing cold, just need it to blow at me instead of front windshield. Perplexed in Houston, TX.

Why my air don't come thru my front ac vents. It blows thru my defrost only. Everything seems normal, it blows cold. Everything seems to be normal.I cant get it to blow thru the vents.I have a broken plastic line.I need to find out where it goes so it can come thru the front vents. Is there any possible way that you can help me get going. It would be a great help if you can help me.

Finally! The simplest thing, I retraced my steps & checked everything I had done. The problem was the tiny black hose was connected to the wrong valve behind the glovebox, now have AC Blowing out the dash. Replies very much appreciated.

I have heat coming out of my defrost vents but no heat or air coming out the front vents of the car. The lever for the actuator door does seem to move up and down freely and you can hear it blowing air but nothing comes out only on defrost.

My air conditioner only blows out air from the defroster and floor and not the front vents.

Cold air blows out top vent but not front vents

All air is coming only from the defrost. No matter where the selector is set, there is no movement from defrost. I removed the vacuum connector from the rear of the selector switch and did not hear or feel any vacuum. No hissing can be heard from under the dash when the engine is running. Thank you in advance for any help

***SOLVED***

I found that the black "plastic" line coming from the firewall to a vacuum "T" was broken. I removed the broken piece and inserted the line into the rubber boot. Works fine now.

Thanks jacobandnickolas for the reply!
