Unhappy Restricted air flow through AC vents

I`m having a issue with air flow being restricted. The AC is icy cold and the fan is working. I`m not getting good flow even with the fan on high. What is going on here? Its not fun to drive when its in the upper 90s with 70% humidity. Is this something easy to remedy? Since I`m not very mechanical, what will this cost to repair. Thank you

You may want to recharge the air con liquid.

Is it every vent, or just some? Does the air feel as cold out of every vent, or is it noticeably colder out of one side of the car vs the other? Does it make a difference if you use the Auto setting (on like, 65 degrees) and let it auto adjust the speed itself?

It does feel cold in every vent but even on the lowest and strongest setting I was just getting cooled. So I went to my local shop and they refilled the R134 liquid.its a 20 mins top.

You may have a blocked pollen filter , try it on recirculate and if it blows harder then it will be the pollen filter needs replacing .

Or....

One of the "doors" that move to direct airflow to your choice of defrost, floor vents and dash vents is stuck.

Old foam in the vent system can degrade and fall apart, blocking movement of critical parts or clogging the system too.

Do you have air flow coming out of any of the outlets other than the dash?

No pollen filter on US market cars

I had the exact same problem when I bought my cat.

The air coming out of the vents was COLD, but it was barely coming out of the vents.

The X308 has TWO fans for the heater/AC ducting. My passenger fan was not working because one of the wires had somehow worn on the framing under the glove box and separated itself. Of course I didn't discover this until I removed the passenger fan assembly and bench tested it and it worked!

What you should do is see if both fans are indeed working.

You can sent the EATC system in re-circulation mode and look at the fans. The drivers side one is accessible once you remove the little pocket above your left knee, and the passenger one is visible if you drop the glove box.

I bet you have one fan non-op.
