Chevy Traverse Air Conditioner Light Blinking [Possible Causes & Fixes]

The Chevy Traverse is a luxurious midsize SUV with a strong leaning toward safety and is packed with a lot of technology to support this initiative. The car’s interior is made to make it comfortable for a smooth drive. One of the comfort and safety functions is the car’s air conditioning system.

However, many of our users have been asking us what is the meaning of the light blinking on your Air Conditioner. So I decided to address it in this post.

In short, The light blinking on a Chevy Traverse’s air conditioner is a warning signal that the clutch on the vehicle’s compressor is not turning the way it is supposed to. The compressor clutch is the main component of a vehicle’s A/C system as it plays a major role in providing cool air.

How does the compressor clutch work on your Air Conditioner?

The compressor clutch is located toward the front of the vehicle right next to the drive belt. It is positioned on the outside of the pulley wheel, it only turns when it is called upon to circulate refrigerate through the system. Meaning it turns on and off depending on the need to provide cool air. The system is electro-magnetic which is what allows it to engage and disengage from the compressor’s pulley wheel.

What causes the A/C light to flash or blink 3 Times?

Several issues can lead to the A/C light flashing in your car:

  • One common cause is an extreme temperature differential, meaning the interior of the car is significantly hotter, or the external environment is exceptionally colder than usual.
  • The problem may also stem from improper refrigerant levels – either too much or too little. A leak in the system often causes insufficient refrigerant levels. Similarly, if the compressor’s drive belt is frayed, worn, or loose, it might prevent the clutch from engaging properly.
  • Issues with the cooling fan can also trigger the A/C light to flash. This problem may be accompanied by a faulty drive belt tensioner, a defective compressor clutch, or a malfunctioning relay.
  • Electrical issues with the compressor, such as improper compressor voltage or sensor faults, can also cause flashing. Defective pressure switches, whether on the high or low side, or a faulty evaporator pressure sensor, are potential culprits as well.
  • The blinking of the A/C light could be a result of a blown fuse, bad wiring to the clutch, or poor grounding, all of which disrupt the normal operation of the car’s air conditioning system.

How to fix an A/C flashing problem

When dealing with a temperature difference issue, you need to switch off the A/C, open the window for ten minutes then switch on the A/C again can help rectify the blinking problem.

Troubleshoot the fans and the relays, even if only one of the fans is working it can result in the flashing of the A/C light. In the case of a loose of a drive belt, tightening it is the first port of call but in the event that tightening doesn’t work, you can alternatively replace the belt with a new one.

To check whether the clutch is still working, turn the clutch with the engine turned off. If offers resistance it means the clutch might be in need of a replacement. Run a diagnostic check on all the components making use of ampere meter, ohms meter, and like devices checking the readings against the expected values.

Some of the components of this device might be in need of replacement or minor repairs. Make use of an auto-technician to help root out any underlying issues. Remember to always check the refrigerate levels and make sure to look for leaks especially if the issue is related to the low level of the fluid.

Conclusion on why is my ac light blinking in my traverse

The blinking of the light of an A/C is due to a number of issues that range from a lack of refrigerating fluid to the more problematic leaks that can be costly.

Having an expert look over the compressor clutch of your A/C system and run diagnostics of any electrical components too help zero in any cause for the signal warning of the blinking A/C.

The Chevy Traverse does not have a record of any major issues with the failure of the AC system but running maintenance and service checks are a good way to make sure the vehicle is always reliable. A working A/C is a necessity to prevent fogging up of the windshield in rainy or cold weather which can limit visibility.
