I hope this is a simple question for someone.... In a '92 Explorer, where is the AC orifice tube located? It seems that the after-market manuals just don't want to tell me that little secret! Thanks very much.
The orifice tube is located in the inlet to the evaporater where the "liquid line" comes from the condenser. Put another way, if you undo the nut that connects the liquid line and the evaporator, the orifice tube is inside.
