How To Know If You Have A Bad A/C Compressor Relay

If your car’s air conditioning isn’t working as well as it should, there’s a good chance that the compressor relay is to blame. The compressor relay is responsible for supplying power to the compressor, and if it fails, the compressor won’t be able to do its job. There are a few telltale signs that can indicate a bad a/c compressor relay. If you notice any of the issues below, it’s important to check the compressor relay as soon as possible.

The Compressor Cannot Be Switched On

The compressor is the heart of the system, and the relay helps to power it. If the relay is damaged or defective, it can prevent the compressor from switching on, which will prevent the system from cooling the air. In most cases, a bad A/C compressor relay will need to be replaced in order to resolve the issue. However, it’s also important to check other potential causes, such as a blown fuse or low refrigerant levels, before replacing the relay. Otherwise, you may end up replacing the part for no reason.

Increase In Energy Consumption

If the relay is not working properly, it can cause a spike in energy consumption. Not only will this make your car’s A/C system less effective, but it can also lead to decreased fuel efficiency and increased emissions. If you notice that your car’s A/C system is not performing as well as it used to, or if you see an increase in energy consumption, it is possible that you have a bad A/C compressor relay.

Inconsistent Cool Air

The A/C compressor in your car helps to circulate cool air throughout the cabin, making it a crucial component of the air conditioning system. If the compressor relay fails, it can cause the compressor to run intermittently, resulting in inconsistent cool air. In some cases, the compressor may also stop working entirely. If you notice that the cool air in your car is inconsistent, it’s a good idea to have the A/C system checked by a qualified mechanic. By having the problem diagnosed and repaired early, you can avoid more extensive damage to the A/C system and keep your car comfortable all summer long.

Warm Air

If the compressor relay fails, the compressor will not be able to function, and the air conditioning system will not be able to do its job. As such, the cabin of the car will become warm, and the occupants will become uncomfortable. In some cases, the car’s cooling fans may also be affected, further exacerbating the problem. If you notice that your car’s air conditioner is blowing warm air, it is likely that the compressor relay is at fault.

Every car owner dreads the day when they have to take their car in for repairs. But if you suspect that your A/C compressor relay is failing, it is important to get it fixed as soon as possible. Not only will this improve the performance of your air conditioner, but it can also help to prevent further damage to your car’s engine.
