Hey everyone.. so it looks like the air flow on my central air vents are really weak, almost non existant, but the top windshield defrost vents are working just fine.

I recently got new trim pieces and since then my central air vents are not working properly, as i said, the air flow is too low. I tried increasing the power but nothing changed (i can hear the blower motor run). I then put the A/C to "MAX" i hear a vent unclogging or opening and suddently all the central vents started blowing out air again (Cold Air 16°/60,8F). When i stopped the MAX setting it stopped once again as i increased the temperature again it was like before (Little to no air coming out of the vents).

Any ideas on what could be the issue? Could it be an electrical issue or a mechanical? Any experiances?

Thank you in advance. :
