Low side low, high side normal on dual evap system

[lbarowski]

2011 Town & Country with dual evaporators. At 90F, high side gradually climbs to 270 psi, low side is about 6 psi. Seems like that would indicate a stuck expansion valve, but there are two expansion valves. Both front and rear AC blow warm (no apparent cooling at all). What happens with a clogged expansion valve on a dual evap system? Not this I would guess. What could this be? Not sure if this happened suddenly or gradually as AC was not used for several months.

Sounds like it is very low on charge.

Recover it & weigh the charge. If it had more than 755 charge, pull the receiver dryer & check for a failed dessicant bag.
