Anyone notice that the center dash vents (either side if the radio) do not blow as much A/C air compared to the outside dash vents?
Car is a '13 GTS.

 

Actually, one of the things I want to ask the service people when I go in for the first service check is that the driver-side centre vent seems to blow somewhat less than the passenger-side one..

 

I spoke to the service writer and he said that its possible that the
vent flaps in the system are not opening all of the way.
I had a few problems back with my 04 CS a/c. It was a
bad module that stopped working correctly. With that car the dash went out 100%, this seems to be about 75-80% velocity compared to the outer vents.

 

I was having the same problem with my passenger side window vent. Turns out the vent control dial was broken. So I stuck a pen into the vent and opened it. The service manager said they had experienced similar problems with other vehicles and ordered the part for replacement.

 

I know exactly what you're talking about. I have the same issue. Very weird. Thought it was normal.
