View Full Version : A/C and vents- cold out of one fresh air vent

My A/C has never been very cold and definitely not cold enough when the ambient temp is 80+. I do have proper charge and the compressor spins.

On a trip this past weekend I noticed something unusual. Out of the passenger side fresh air vent the A/C was very cold, exactly like it should feel, but out of all the other vents it was mildly cold as per usual.

What would cause the correct cold air to come out of only one fresh air vent and not the other and then why wouldn't the rest of the vents get the cold air as well?

My thoughts about it are here in the APACT comments.

I asked about this a few months ago. Mine is exactly the same no matter if I top the r-134a off or not.
