Hello, your vehicle would have an expansion valve by the front evaporator core and one by the rear one. Whether or not you need one is subject to proper diagnostic testing. It's a difficult job to replace one, as you need to access the evaporator boxes. However, if you have debris within your system, for example, or a leak, it would be necessary to repair.

From my parts film, without a VIN specifically:

Front: 80220-STX-A01
Rear: 80221-S0X-A51

Additionally - ‘IF’ the expansion valve is restricted or otherwise malfunctioning - the A/C *manifold gauge set* would indicate so via pressure readings..
