Where is the cool air going?

ford

#1

The AC blows really cold but it just trickles out of the vents. It sounds like it is blowing really hard but it is not getting to the vents.


#2

Check the defrost outlets at the bottom of the windshield. If you find airflow there, it means that you have a problem with the vacuum that goes to the climate control system.


#3

A check of system pressures would tell you if the compressor is cycling correctly. I suspect the evaporator is icing up and blocking airflow. Check and see if the compressor ever cycles (while stopped). This is a crude technique but you should be getting some cycling action (unless you make the test in the sun with the windows down).


#4

it does cycle on and off. I thought maybe something is disconnected/loose or stopped up since I can hear the air blowing hard but it just doesn;t get to the vents


#5

Yes, like a disconnected vacuum hose.


#6

yes, a vacuum problem somewhere.
