Blower motor is working, it is not blowing as hard as it used when I first bought it though.
I will check the pressures and read them next time.


Fords tend to have dye from the factory.

No it is a cargo van, it only takes 40ozs, yeah what im leaning at is a partially clogged evap in combination with lower ambient temperature and weak blower motor not moving enough air across the coil. Noticed early this morning when it was colder outside that lines started freezing right away, I also noticed the problem the first cold day we had in Florida.

Sorry to bring back an old thread but found the problem to be a bad low pressure switch, hopefully this will help someone, thank Chris and everyone for their replies.
