My wife owns a 2004 saturn vue. My friends just replaced the engine in it and now were runnning into more problems. a few of them are: the a/c, defrost and recirculate buttons arent working. the lights dont come on or anything. another thing is when we try to change where the heat is coming out it only comes out by the windshield even when we rotate the **** to the floor or the other vents. any help would be appreciated.

 

I don't hold any VUE documentation, so I'm of no help other than to suggest checking all your fuses and wiring connectors. Things do get bumped and jostled with a major engine refit ...
