Flap for fresh air/ recirc air have a tendancy to get stuck and thus causing the clicking noise. dont envy you on the repair as they are hard to get to.

Inside cab blows out hot air controls are off but air still comes out


OUTSIDE AIR: Press this button to direct the system to use outside air.
Pressing the OUTSIDE AIR button will cancel the RECIRCULATION button.

RECIRCULATION: Press this button to limit the amount of outside air entering your vehicle.
This is helpful when you are trying to limit odors entering your vehicle or attempting to quickly cool down the interior. Pressing RECIRCULATION will recirculate air continuously.

RECIRCULATION is used when the fan control is OFF to limit odors, outside air and dust from entering your vehicle. All button lights will go off. The last setting selected will activate when the blower is turned back on.
Pressing the RECIRCULATION button will cancel the OUTSIDE AIR button. To return to normal operation and to prevent stale air, be sure to return the OUTSIDE AIR.

Between HEATER and BLEND mode, outside air is forced to reduce window fogging. If the RECIRCULATION button is pressed, the LED indicator will flash three times indicating that forced outside air is activated and RECIRCULATION is not available.

I think what your experiencing is normal. If you want to keep cold air form coming into the cabin, press the recirc button.

I hope this helped, icon_e_biggrin.gif

Clicking on passenger side when truck running goes off when pressing air recirculate button


Most likely an issue with the vacuum actuator for the heater blend door. There may be some binding in it, or a vacuum leak at the actuator diaphragm.

Heater and air condioning switch keeps making clicking noise


The noise is one of the actuators that moves the air flow doors into different positions. Common problem. When the noise happens, move the temp. control from cold to warm. If the noise goes away, it is the temp. actuator. Or, press the recirculation button to go from fresh air to recirc. If the noise goes away, it is the recirc. actuator. Or, change the mode from vent to heat. Could be the mode actuator. Usually the temp actuator acts up.

How to retrieve DTC:
The heater control panel has self-diagnosis function. To run the self-diagnosis function, do the following:
1.Turn the blower fan OFF.
2.Press and hold the recirculation control switch and the rear window defogger switch down.
3.Turn the ignition switch ON (ll).
4.Release both switches. The recirculation indicator and the rear window defogger indicators come on. The recirculation indicator goes off 3 seconds later and the A/C indicator comes on, then the self-diagnosis will begin. About 10 seconds later, the self-diagnosis will finish and the A/C indicator goes off.
- If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate a faulty circuit or component.
- If the system is ok, the recirculation indicator stays off.

- In case of multiple problems, the recirculation indicator will indicate only the DTC with the least number of blinks.
- In case of an intermittent failure, the heater control panel will store the DTC until the ignition is turned off.

When i press the ac button it blinks three times but does not turn on. 2007 Tahoe LT


If your vehicle is equipped with automatic climate control, this should help.

Recirculation Operation
The HVAC control module controls the air intake through the recirculation actuator. The recirculation switch closes the recirculation door in order to circulate the air within the vehicle. The outside air switch opens the recirculation door in order to route outside air into the vehicle. Regardless of the blower motor switch position, recirculation is available only in the panel and bi-level mode switch positions. Including the OFF position. The mode switch must be placed in either the panel or bi-level position before the blower motor switch is placed in the OFF position. In order to reduce windshield fogging, outside air is circulated when the mode switch is in the defrost or defog positions. If the recirculation switch is pressed into the ON position when the mode switch is in an unavailable mode position, then the recirculation switch LED will flash 3 times. If the HVAC control module detects a fault with the recirc door the HVAC control module will try to drive the actuator for a predetermined amount of time, to outside air, which is the defaulted position for the recirculation actuator

Max air button does not respond


"MAX" ONLY puts the climate control in the RECIRC mode. Door modes change to " RECIRCULATE" interior cabin air back to be RE-COOLED, instead of using HOT OUTSIDE air to cool. If the problem is in the panel, complete replacement is required. Hope this helps

Climate control system


Sounds very much like the cabin fan speed controller which is about $120.00 at SaabSite. It is mounted on the evaporator housing in the passenger footwell. You will have to remove the center console side panel and the panel beneath the glovebox to expose it. It must be mounted with thermal transfer paste to ensure that the contact with the heat sink is maximized. Here is the controller:
