I noticed that after I put it back in - but my problem is that the recirc flap will not go into recirc mode - it is always open (to allow fresh air in). When pushing button with both up and down arrows - it will move about 1 inch - then go back (fresh air). When you rebuilt your system, did you test vacuum system before you recharged it? I have already changed the change over valve for the recirc vac pod, no difference. I've replaced all hoses, compressor, condensor, dryer, sensors, vac pods - I am almost ready to get re-charge - but would really like to have recirc mode working first - Thanks
