A/C Expansion Valve: Description

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

The A/C expansion valve controls the amount of refrigerant entering the A/C evaporator and is of a thermostatic expansion valve (TXV) design. The A/C expansion valve consists of an aluminum H-valve type body with an integral thermal sensor and is located at the dash panel between the A/C refrigerant lines and the A/C evaporator. See Fig 1.
