hey guys so when i was driving my gtp today i tried to put the air on. when i move the fan switch from off to 1-4 the headlights turn off as well as the screen that displays oil life, mpg, fuel used.... but when i switch it to 5 the screen turns back on as well as the headlights. When switched to 1-4 air doesn't come out of the vents but on 5 it goes on to how it usually would. Any ideas on whats causing this?
