Before spending any serious money on it, it may be worth a try to evacuate and re-charge the system and/or take it by your Toyota dealer / technician to diagnose. Interesting, I didn't know the HVAC system had trouble codes that you could look up.

26 is the rear inlet air temp sensor. Could also be the rear A/C amplifier or harness.
47 is the rear air mix damper control servomotor. Could also be the rear A/C amplifier or harness.

Since you have two codes relating to the rear a/c, it could be the harness, amplifier (ECU) or just a loose or corroded plug.

Thank you a lot ,it is great to know about these two codes
Since I had replaced rear temp.sensor and still have code 26,I we'll try to do tracing for the wire harness and trouble shooting for the amplifier
Any how I have difficultly to find electrical wire diagram for 2001 lx470
