SOURCE: ac vent problem

Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.

SOURCE: bi-level on heat/ac does not blow air out the front dash vents. It is at least partially vacuum controlled.

Check under your hood for broken or loose vacuum lines. Also, the pot on the hood? i believe, on that one. There should be avacuum line running to it. Looks like a little bowling ball. With your engine running , listen for a hissing.

I have a 2006 saturn ion 2. Just recently, my ac is draining into the passenger floor board. How do i fix this ?


Bulletin No.: 03-01-39-011B
Date: November 22, 2005
TECHNICAL
Subject:
Water Leaks Into Passenger Compartment Through HVAC Module Condensate Drain Tube When Parked on Incline/Uphill Position (Install Auxiliary Drain Tube Extension)
Models:
2003-2006 Saturn ION Sedans and Coupes
Supercede:
This bulletin is being revised to include the 2005 and 2006 model years. Please discard Corporate Bulletin Number 03-01-39-011A (Section 01 - HVAC).
Condition
When vehicle is parked on an incline with the front end up during a rainstorm or when driving uphill during a rainstorm, water may leak into the passenger compartment through the condensate drain tube opening of the HVAC module.
Cause
Water may drain out of the cowl drain, then drain down the front of the dash panel in the engine compartment and seep into the HVAC module condensate drain tube opening. The water then collects in the heater core cover and upon acceleration may leak into the passenger compartment through the heater core cover seams.
Correction 1. Open the hood and locate the HVAC module condensate drain tube in the engine compartment on the right side of the dash panel.
Important: During installation of the auxiliary drain tube, do not make contact with the HVAC module foam gasket located at the base of the HVAC module condensate drain tube. If the auxiliary drain tube is pushed on too far and makes contact with the foam gasket, water may leak into the passenger compartment.
2. Slide the auxiliary drain tube onto the HVAC module condensate drain tube and make sure that the auxiliary drain tube is angled downwards after installation.cansmo_121.gifcansmo_122.gif

Where is cabin air filter location


Hi if you have the 3.8 then follow these instructions.

Hi

  1. Left sound insulator panel.
  2. HVAC air filter access cover.
  3. Pull first filter out using filter tab. Filters will bend to clear accelerator pedal.
  4. Pull the second filter out using tab.
  5. Pull the third filter out using tab.
Install or Connect

Important
  • When installing the filter care should be taken so that the filter does not become dislodged from the channel inside of the HVAC module.
  1. First filter in case. Use the tab and raise the filter parallel, so that the leading edge catches on the holding rib.
    • A long thin bladed screw driver may be useful in lifting the filter parallel to the HVAC module.
  1. Engage the second filter in the tab of the first filter and slide it into the remaining channels of the first filter.
  2. Use the tab and raise the filter parallel, so that the leading edge catches on the holding rib.
  3. Engage the third filter in the tab of the first filter and slide it into the remaining channels of the second filter.
  4. Fold the second filter tab down and the third filter tab up and over the second.
  5. HVAC air filter cover.
  6. Left sound insulator

I changed the battery on 2006 Trailblazer SS. Now I can only get AC from my windshield and floor vents. Nothing from the dash vents. Also the temp control only gives coldest temp. I have checked fuses...


once you disconnect the battery your body control module loses power and memory you have to get some one with a scanner with reprogramming capabilities and have the computers reset ,dealer?

04 Tahoe AC blows hot air on drivers side but resets if restarted


A educated guess I would have to say there is a problem with HVAC control module ! electronics you know ! But that's not the way to do things ! There could be codes stored in the module. The Chevy dealer my have a reflash bulletin for this problem . Then can reflash , reprogram the control module ! The first place to start is checking for codes in the HVAC module.
The HVAC control module is a class 2 device that interfaces between the operator and the HVAC system to maintain air temperature and distribution settings. The battery positive voltage circuit provides power that the control module uses for keep alive memory (KAM). If the battery positive voltage circuit loses power, all HVAC DTCs and settings will be erased from KAM. The body control module (BCM), which is the vehicle mode master, provides a device on signal.
Air Temperature Sensors The air temperature sensors are a 2-wire negative temperature co-efficient thermistor. The vehicle uses the following air temperature sensors:
?€¢
Ambient Air Temperature Sensor

?€¢
Inside Air Temperature Sensor Assembly

?€¢
Inside Air Temperature Sensor Assembly-Auxiliary

?€¢
Upper Left Air Temperature Sensor

?€¢
Upper Right Air Temperature Sensor

?€¢
Lower Left Air Temperature Sensor

?€¢
Lower Right Air Temperature Sensor

?€¢
Upper Air Temperature Sensor-Auxiliary

?€¢
Lower Air Temperature Sensor-Auxiliary
A signal and low reference circuit enables the sensor to operate. As the air temperature surrounding the sensor increases, the sensor resistance decreases. The sensor signal voltage decreases as the resistance decreases. The sensor operates within a temperature range between -40?° to +101?°C (-40?° to +215?°F). The sensor signal varies between 0-5 volts.
The input of the duct air temperature sensors are different from the ambient and inside air temperature sensors. The HVAC control module converts the signal to a range between 0-255 counts. As the air temperature increases the count value will decrease.
If the HVAC control module or auxiliary HVAC control module detects a malfunctioning sensor, then the control module software will use a defaulted air temperature value. The default value for the ambient and inside air temperature sensors will be displayed on the scan tool. The default value for the duct air temperature sensors will not be displayed on the scan tool. The scan tool parameter for the duct air temperature sensors are the actual state of the signal circuit. The default action ensures that the HVAC system can adjust the inside air temperature near the desired temperature until the condition is corrected.
The ambient air temperature sensor mounts underhood and can be affected by city traffic, by idling, and by restarting a hot engine. Therefore, the HVAC control module filters the value of the ambient air temperature sensor for temperature display. The ambient air temperature value is updated under the following conditions: Or you can just buy a new control module an hope that it fixes it. $89.00 at www.partsgeek.com

Removing a heat-core


not only does the dash require removal,but you will also need to completely remove the hvac module assembly from the vehicle after the dash is out of the way. the module will have to be diassembled in order to replace the core.--hvac module removal will require ac refrigirant recovery and coolant replacement.--it sounds like a lot of work but should only take you about one good saturday if its your first time around the block.---good luck.
