SOURCE: Heater only blow out the vents

There are servos that move air control gates, some were controlled electrically, and some were vacuum. It sounds like there's a vacuum line off the vacuum reservoir under the hood, or a vacuum line has came off one of the servo diaphragms.

Could be the blower motor, I have had and am continuing to have the same problem. Replacing the motor did help though.

Under the dash drivers side there are mode motors that control where the air comes from replace bad one or both the bottom one is recirculate. You could take a volt meter and see which one has power when you push button

Need info on heater mode door operation


The mode door actuators are reversible, 12-volt direct current (DC) servo motors. The heating-A/C systems on this vehicle use two mode door actuators. One for the panel/floor-air door and one for the defrost-air door.

Both the defrost door actuator (1) and the panel/floor door actuator (2) and the are located on the driver side end of the HVAC housing (3), close to the dash panel.


All actuators (1) are interchangeable with each other. Each actuator is contained within an identical black molded plastic housing with an integral wire connector receptacle (2). Each actuator also has an identical output shaft with splines (3) that connects it to its respective door linkage and three integral mounting tabs (4) that allow the actuator to be secured to the HVAC housing. The mode door actuators do not require mechanical indexing to the mode-air doors, as they are electronically calibrated by the A/C-heater control.
OPERATION

The mode door actuators are connected to the A/C-heater control through the vehicle electrical system by dedicated two-wire leads and connectors of the HVAC wire harness. The mode door actuators can move the defrost-air door and the panel/floor-air door in two directions. When the A/C-heater control pulls the voltage on one side of the motor connection high and the other connection low, the mode-air door will move in one direction. When the A/C-heater control reverses the polarity of the voltage to the motor, the mode-air door moves in the opposite direction.

When the A/C-heater control makes the voltage to both connections high or both connections low, the mode-air door stops and will not move. The A/C-heater control uses a pulse-count positioning system to monitor the operation and relative position of the mode door actuators and the mode-air doors. The A/C-heater control learns the mode-air door stop positions during the Actuator Calibration procedure and will store a Diagnostic Trouble Code (DTC) for any problems it detects in the mode door actuator circuits.

The mode door actuators are diagnosed using a scan tool (Refer to 28 - DTC-Based Diagnostics/HVAC - Diagnosis and Testing).

The mode door actuators cannot be adjusted or repaired and must be replaced if inoperative or damaged.

Why my heat works on my 2004 Chrysler Sebring but it only blows out from my front dash only and not the floor or Front dash defrost?


More than likely a bad vacuum or electric actuator, or bad vacuum line. Actuators control the mode doors to change from floor, vent, and defrost.

My 07 Chrysler aspen will not start but my battery is good, all accessories work, my electronic throttle control light stays on, and there is also a small red light flickering


actually your aspen would start then die out after about 3 seconds. if you have tried this repeatedly, Now it does not start at all (your ECU is now locked up since it thinks you were trying to steal the vehicle). The little red light is your antitheft system. Your remote head key has failed. You can find a locksmith that does these at www.findalocksmith.com or you can have it towed to the dealership for a computer reset and another key.

Blower VENT DOOR NOT WORKING RIGHT ON 2009 SEBRING


Either something blocking or binding the actuator or actuator or door failure or calibration,if you hear a clicking noise when changing to vent mode under dash area this indicates the actuator internally slipping and will need to be replaced

Heater is just warm, when you turn on the defroster on high takes a long time to defrost. I have had the car since 2007 and this is not normal. p.s. already changed the thermastat


You could possibly have a bad heater control valve if the car has one. Another item maybe a stuck or faulty blend air door. This would be the actuator most likely. It may not be shutting off all the way to allow complete heat through. The other possibility is a partially clogged heater core.

ALL I GET IS COLD AIR FROM HEATER. HAVE CHANGED THERMOSTAT, BLED COOLING SYSTEM AND HEATER HOSES GOING TO HEATER CORE ARE BOTH HOT. SOMEONE TOLD ME ACUATOR BUT IT MOVES FROM VENTS TO DEFROST AND FLOOR...


There is also an actuator for temp control. It moves doors in the duct work for heat and for cold air. that is the one that needs replacing. the one you are talking about just moves airflow positions.

Heater-A/C control calibration procedure


I found these instructions when my heater suddenly stopped working. Start car, while car is parked turn temperature to 75. Hold down the floor, defrost/floor and the defrost buttons. Wait til the temp light starts blinking, release. It will blink for a while and either recalibrate and be fine like mine or you could get 1 of 16 different trouble codes. Hope this helps. ;p ~Redmoon

Pull the AC control in the dash and verify that there is vacuum going to it, all the different air diversion doors are operated by seperate vacuum motors controlled by the ac control head in the dash, as you switch it it sends vacuum to the correct location to work that door for the desired air outlet, dash, floor etc..
