No airflow out of the dashboard air vents. The rear seat vents work and cold air comes out. How do I repair the front vents to get the air flow?
air blows warm on drivers side @100 degrees and pass side @70 deg. Code left was B1343,(air inlet door movement fault). I haven't fixed it yet.I don't know where the door is.Please advise.
The Heating system works good on the drivers side but the passenger side dose not blow hot air.a/c works fine for both sides diver.passenger. It's just the heating problem how do I fix or what is the cause thank tom
one side blows cold another blows hot
Hot air from drivers side vents. Where is the actuator located?
Warm air flows on driver side cold air flows on passanger side. The air flow on floor on both sides is only cold. General airflow is restricted trough vents
Cold air only comes thru vents on passenger side while air on driver's side is warm or just regular vent air coming from outside of the car. Not fixed because i don't know what is the problem.
im not sure if this is the same or not i feel air from defroster but not the vents in in the dash my rear console blower doesnt come on but i can at times feel air blowing when car is in motion ,none of my blower motors come on except one time a week ago rear fan started to blow then it stoped any help where i should begin to look
Neither hot or cold air coming from any of my vents. Need help with this fast!
Air delivery and temp is ok but the air comes both from the windshield and the floor (both at the same time) I cannot get it to change to the dash port outlets.
hot on drivers side , cold on passenger side
Cold only on drivers side, pass side feels like vent, no heat available anywhere in pass compartment....... all heat feels like vent
blows cold air with heat on
Cold air on driver side and hot air on passenger side.
(HVAC) temperature and/or air delivery on passenger side blows out cold air all the time. Even if you shut odd passenger heat or AC control.
The only way it is stopped is to shut off the main Climate control switch on the drivers side

Heat is coming out of the driver's side vent when a/c is on. It hasn't been repaired yet.
Air only blows from defroster and floor vents. Cannot change mode.
