Still at the shop in Montreal.. New front diff under warranty, on a truck with 14000 miles lol. Not a good sign if you ask me.

I have a set of 35x12.50x20 and new Wheels for it waiting to be picked up

 

[Goodinblack]

14k?

 

[YuCanada]

So my AC decided it does not want to work anymore. I tried to search for answers but can't find anything even though I remember reading about a similar problem on here before..

I press the ac button and it flashes a few times and stops. It's still really warm here and would like to fix it or at least figure out what's wrong.

Anyone know what's up?

#07-01-38-006: Information for Vehicles with HVAC Control Module A/C Indicator Blinking Due to Low Battery State of Charge - (Aug 20, 2007)


Subject: Information For Vehicles with HVAC Control Module A/C Indicator Blinking Due to Low Battery State of Charge


Models: 2007-2008 Chevrolet Avalanche, Silverado, Suburban, Tahoe

2007-2008 GMC Sierra, Yukon, Yukon XL

with Manual Temperature Control HVAC System (RPO CJ3)




--------------------------------------------------------------------------------

An Air Condition (A/C) button on the Heating, Ventilation and Air Conditioning (HVAC) control module may blink when the A/C system is activated. The blinking indicator will turn to a solid light after cycling the A/C button or ignition key.

This condition may be caused by a low battery state of charge on a PREVIOUS ignition key cycle. This condition may be due to situations were an unsold vehicle is parked for long periods of time as part of a dealership's unsold inventory. The A/C indicator begins to flash If the battery voltage falls below 9.5 volts. The low voltage condition may occur during an engine crank or if the vehicle is parked and a normal battery state of charge is not maintained.



Run the vehicle to charge the battery or connect a battery charger. (If the charging system is operating as designed , the battery surface charge should indicate 12+ volts.)
Do Not Replace the battery, HVAC control module or ECM.


If the A/C indicator continues to blink, use the Tech 2® to help determine the cause.
• Connect the Tech 2 and build the vehicle.

• Select Powertrain.

• Select Engine Control Module (ECM).

• Select Data Display.

• Select Cooling/HVAC data.

• Make sure that there has been an A/C request signal.

• History should indicate any causes.

If necessary, refer to SI for further information on HVAC system diagnostic procedures.

#07-01-38-003: Information for Vehicles with HVAC Control Module A/C and Recirculation Indicators Flashing


Subject: Information for Vehicles with HVAC Control Module A/C And Recirculation Indicators Flashing


Models: 2008 Buick Enclave

2007-2008 Cadillac Escalade Models

2006-2007 Chevrolet Monte Carlo

2006-2008 Chevrolet Impala

2007-2008 Chevrolet Avalanche, Equinox, Silverado, Suburban, Tahoe

2007-2008 GMC Acadia, Sierra, Yukon Models

Condition/Concern
Some customers may comment that the Air Conditioning (A/C) indicator on the Heating Ventilation and Air Conditioning (HVAC) Control Module flashes then turns off after they press the A/C button. Others may comment that the Recirculation indicator on the HVAC Control Module flashes then turns off after they press the Recirculation button.

This is normal operation for the HVAC Control Module and indicates that the A/C or Recirculation function is not available at this time.

Reasons that the A/C may not be available (calibrated values vary by program) are listed below. Consult the appropriate vehicle Service Information (SI) for detailed HVAC Description and Operation:

• Ambient Air Temperature is too low (if equipped with Ambient Air Temperature Sensor)

• Vehicle voltage less than 9.5 volts

• Refrigerant Pressure too low

• Refrigerant Pressure too high

• Engine Coolant Temperature too high

• Engine is not in RUN

• HVAC Control Head is in the OFF position

Reasons Recirculation may not be available: Mode switch in Floor, Defog or Defrost mode.

The reason(s) A/C is currently disabled can be viewed with a Tech 2® by navigating to HVAC Data display and viewing the "A/C Permission" parameter.

Recommendation/Instructions
Do not replace the HVAC Control Module for a flashing A/C Indicator or flashing Recirculation Indicator, as this is normal operation.

Seems like "low voltage" is causing it a lot. I'm guessing you haven't driven it in a while? Also could be low pressure switch or the high pressure switch. E



I just googled "tahoe ac light blinks" "tahoe ac blinking light" "tahoe ac blink 3 times"
