ISSUE:
A lack of A/C cooling may be observed on some vehicles. This may be due to an incorrect crimp on the evaporator inlet tube which retains the orifice
tube in the proper position. This may allow the orifice tube to slip and lodge in the evaporator core. This condition may cause a restriction or appear that
the orifice tube is missing, resulting in lack of cooling.
ACTION:
Replace the evaporator core and orifice tube. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1.
Verify the concern using the procedures outlined in Section 12 of the 1994 Aerostar, Ranger, Explorer Service Manual.
2.
If the pressure cycling time test indicates a missing orifice tube or an evaporator restriction, recover the refrigerant using an approved refrigerant
recovery system.
3.
Disconnect the evaporator inlet tube and look for the orifice lodged inside the evaporator core.
4.
If the orifice tube is lodged inside the evaporator core, replace the evaporator core and orifice tube. If the orifice tube is not lodged in the
evaporator core, refer to Section 12 of the 1994 Aerostar, Ranger, Explorer Service Manual for diagnostic procedures.
5.
Evacuate and recharge the A/C system according to procedures outlined in Section 12 of the 1994 Aerostar, Ranger, Explorer Service Manual.
