Your car is a orfice tube type system. It does not have a mechanical exspansion vlave. The orfice tube is located in the liquid line running from condensor to bottom tube entering evaporator. Your symptom could indicate a low charge,debri blocked orfice, or a failed compressor. Proper charge is critical. We always start diagnoses by recovering all refrigerant from the system then recharging with the exact specified charge to verify its correct before condeming and parts of the system.
Thank you!! I was a "mechanic" years back but things have changed! I evac'd the system and recharged with 32oz of 134A but could get a good high side reading, ergo the expansion valve thought. Thanks for the up-tick on the orfice tube as I'd forgotten about those little devils!. I'll give it a shot.

Some Fords have the orfice at the fitting where it connects to the condensor. You remove the orfice and check for debri clogged on the screen surrounding it. Some are made into the liquid line and on those the line needs to be replaced. Good Luck old mech.
