Having difficulties with an air conditioner.

2006 KR F150. The air blows, but not cold. I just had everything checked in regards to pressures, freon, etc., but still only blows ambiant temperatures.

Any thoughts? Thank you.

 

It's possible that you could have a blend door issue. Common problem with most Fords. Run a search on here for blend door and you'll have enough reading material for an entire day.

Second what MCDavis says.

 

Are you sure that the compressor clutch is working correctly?
It may be slipping at higher RPMs.
