Depends on the ambient air temperature, humidity level, and type of refrigerant used.
Coming out of the vents around 43 degrees
The air is probably too cold causing condensation at the vents. try increasing the air flow which will warm it a few degrees.
check to see if the controls for the vents are working, there is ususally a vaccum control unit and it may mot be working on the rear vents. hope it helps. duboff
I would think both. Cold air from the room goes in the bottom and warmer air comes out the top.
you need to replace the vacuum.
no
because when you first turn it on, hot air blows from it... thats just how it works, then after a while cool air comes
It depends on how cold you want the area that your using the air conditioner on.
Ceiling. Cold air fails
try 78 degrees when cold
Vents are uaually operated by vacuum. Chances are, you have a vacuum leak at the directional valve or at the back of the air controller itself. All of these are in or under the dash. Good luck.
Cold air return vents are the ones on the wall
