When my heat is on, hot air come out of the 2 upper driver side vents and warm air comes out of the far right passenger side vent. But cold air comes out of the left passenger side vent (the one by the passenger window). My question is Why?

 

i kinda have the same problem. When i have the heat on and it's going through the windshield vents, my regular driver and passenger vents blow out cold air (from outside?) dunno if this is normal or not.

 

is that lever on the left side of your air control thing down or up? for heat it should be down.

 

oh now i feel silly thanks man...didn't know that
