The egr valve is located on the top rear of the engine. It bolts on and is easily removed.
It meters liquid high pressure refrigerant into the evaporator which is located in the heater housing under the dash. It controls refrigerant flow to keep the evaporator coil from icing up.
The expansion valve is located inside the evaporator core housing on the evaporator core. If you see the large and small pipes coming through the firewall on the passenger side of the engine compartment and trace them into the plastic box behind the glove box, you will find the evaporator core inside this box and the expansion valve is the little aluminum block that is in between those pipes and the evaporator core. It should have a little quarter- like bell on the rear of it. Hope this helps and is in time.
