Customer Question

Is there a guide on how to replace the A/C Expansion Valve for a 1999 Dodge Caravan, 3.8L V6?

Optional Information:
Year: 1999
Make: Dodge
Make (other): Caravan
Model: Sport
Engine: 3.8L V6

Already Tried:
replaced radiator, condenser, added new refrigerant and UV Leak Detector refrigerant. The problem is that the A/C system won't absorb refrigerant as quickly as it should. It seems like the A/C Expansion Valve is clogged and needs to be replaced. A how-to guide would be helpful.
