Question about 2005 Chrysler Pacifica

Can not adjust the direction of air flow for the heater or defros

Problem started when I noticed the defroster did not blow on the windshield. Now i have noticed that even if you select different vent directions, you only get air flow from the dashboard vents. No air to the floor or windshield, even if you select those locations for air flow. It seems like the dampers are are not opening/closing to redirect air flow. In the past I have already replaced the module (at that time the fan would not work at all).

    Even when I turn the defroster on, no air comes out where it should. It all blows out of the dash vents.

Why does my 1993 buick roadmaster heat fine but most times the blower won't blow on my windshield to defrost?


Are you referring to the blower NOT blowing air or it is blowing air but will not direct the flow to defrost?

1998 GRAND CHEROKEE BLOWS ON DEFROST ALONE


Hi I have a 2002 JGC ltd and it is most likely your dampeners or louvers located behind your temp controls (inside the dash) for driver and passenger sides that control the direction of air flow from air outside in, circulation, heat to windshield, centre and or to floor etc. I had a friend that had heat only to the passenger side and cold air blowing to driver side. He took it in and they replaced stuck dampeners and it was not cheap. Sounds like the tipical problem with heaters.

Air flow issue- intermittently blows from wrong vents


This is a common problem on this site.
In your case I would look for a vac leak or a sticky blend door.
Since the direction of air flow changes when you are accelerating, I'm going to guess the blend door or doors are controlled by engine vacuum. There may be a vac leak between the dash and the engine, or the blend door may not be able to move back and forth correctly.
Defrost is the default position when a problem occurs, to make sure the windshield is clear of fog or frost.

A/C will only blow through defrost vents


Common question on this site. On late model cars, the vents are controlled by blend door motors. Small electric motors open and close doors to direct air flow.
Chances are you have a blend door that is stuck or a failed motor.
The default position is the defrost to make sure the windshield is always clear.
Someone will need to look behind the dash to see if all of the doors will move on demand.

Little heat


Check the air divert-er door, does the air blow any harder when the panel controls are set to any other direction? If so check for blockage in the defrost vents.

prev.gif next.gif HEATING AND AIR CONDITIONING Refer to Section 1 for discharging and charging of the air conditioning system. The heating system provides heating, ventilation and defrosting for the windshield and side windows. The heater core is a heat exchanger supplied with coolant from the engine cooling system. Temperature is controlled by the temperature valve which moves an air door that directs air flow through the heater core for more heat or bypasses the heater core for less heat. Vacuum actuators control the mode doors which direct air flow to the outlet ducts. The mode selector on the control panel directs engine vacuum to the actuators. The position of the mode doors determines whether air flows from the floor, panel, defrost or panel and defrost ducts (bi-level mode).

Can't change air flow direction on ac/heater control. Only blows up to windshield.


It will be a cable that will be disconnected. or broken. Youll have to take some of the dash apart to see the cable and follow it to the switch. Dont be affraid to take some things apart and when you cant see, use a mirror to help you see behind the dash. work the control and watch the action. You will fix this dont get frustrated. good luck

Heater is blowing but its cold air not hot air 2000 expedition


Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.
