AC blows warm on drivers side but cold on passenger side but no dual controls.WHY???

Hi ihad this sameproblem last week my 06 accord it blows warm air but my passenger side blows cold air. So i took my car to the dealership and after and hour my service advisor called me and to tell me the problem, my Air Mix Motor was stuck or not working properly so he replaced it with a new one part no. 79160-sda-a14 now my a/c works like a new one...

Sometimes when an a/c system is slightly low on charge one side may get cool and not the other, this may be what is happening with your 2005 Honda Accord. I would suggest you have your a/c system checked for proper charge, if it is low the system should be evacuated and recharged to the correct level and inspected for leaks.
