It would seem unlikely, but when the 210 cooling variance problems first came out ten years ago or so, it was noted that any refrigerant performance problem would show in this fashion, cool on the right, warm on the left. One issue that I'm not sure I ever saw was a reported problem with the storage capacity of the receiver-drier. It is a chamber for accumulating liquid refrigerant and if the effective volume is reduced it affects performance.

The possibility of a heater issue should be easy to eliminate. The actual values for the two heater core temps would be the first place to look.

The actual value #5 is evap temp and 25deg C is almost no AC. You should get down to close to "0" atleast below 10. I expect 4-5deg C usually at 50mph. If you are still only getting 25 you have a serious refrigeration issue. What is the low side pressure, that is what matters for diagnostics. At 25 deg evap, low side is probably 70psi or more.
