Question TXV or TXVs

'04 E350 Super Duty Club front a/c 60 degrees, rear a/c warm, blend doors working. I figured out there's a TXV on the rear evap, is there another TXV on the front evap? Can these evaps be blown out or is flushing safer? Thanks So Much!

The front A/C evaporator operates via a Fixed Orifice Tube or simply "orifice" tube. Not sure what's meant by "blown out" but like any other A/C system the best approach is a chemical flushing of the entire system. You'd want to clean or better yet replace the FOT up front and proceed with the flush.

Sorry I meant, blown out with compressed air.

As I said the proper way to do a "flush" is with chemicals intended for A/C system use.
