The 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, what is the meaning of the light blinking on your AC.
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 AC?
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.
A number of issues can cause the A/C light to flash, among these is an extreme temperature differential. That is to say, if the temperature is too high inside the car or if the temperature is too cold outside the vehicle.
Another issue could be that there is not enough or too much refrigeration in the system, insufficient refrigerate can be a result of a leak in the system. If the drive belt of the compressor is frayed, worn, or lose it can cause the clutch to not engage properly.
The same goes for a case where the is a fault with the cooling fan. Along with these is a faulty drive belt tensioner, faulty compressor clutch, and maybe its relay.
If the compressor is suffering from electrical issues, these can be after the compressor voltage or the sensor. Defective pressure switches on either side, high or low, and/or a faulty evaporator pressure sensor. The effects of these result in the blinking of the car’s A/C. A blown fuse or bad wiring to the clutch can also be a problem, even poor grounding.
How to fix an A/C flashing problem
When dealing with a temperature difference issue you need to realize switch off the A/C, opening the window for ten minutes then switching 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.
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.
