Low side low, high side normal on dual evap system

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.
