Dodge Avenger A/C Compressor Clutch

There are several components that make up a Dodge Avengers air conditioning system, which works together to produce cool air in the cabin. The Avengers main system transforms the liquid refrigerant into a cool gas that chills the vehicle’s cabin. Explore the A/C system parts available for the Dodge Avenger.

When should the Dodge Avenger compressor clutch be replaced?

The Dodge Avenger sedans clutch is what makes the system function properly. When the A/C unit is turned on, the liquid refrigerant is compressed into the system. This begins the process of turning the liquid into a cool gas. The compressor clutch then alerts the A/C compressor to start or stop this process. If warm air is blowing into the cabin or no air is coming out, then the A/C compressor is not working and you should consider replacing it.

What does the high-pitched whistling sound indicate?

Noise coming from the Dodge A/C system can be a regular part of its operations or it can indicate a developing or existing problem. If there is a high-pitched whistling sound, it’s most likely the result of aging A/C parts rather than some type of systematic damage. These problems may include aging A/C belts or worn-out fan bearings. These problems occur in some vehicles with 150,000 miles or more. If the sound lasts for more than 15 seconds after the air conditioner is turned on, then the A/C system will need to be fixed or replaced.

What is the Dodge Avenger’s A/C compressor clutch relay?

The relay provides an electrical charge that turns on the power of the A/C system. Problems with the electrical relay include the A/C system not turning on, no air cooling, or weakened cooling. If this occurs, the relay and possibly the entire A/C system will need to be replaced.

What can be done when the compressor clutch doesnt engage?

In the Avenger sedan, the electrical charge from the compressor clutch relay engages or disengages the A/C system. When the engagement doesn’t happen, then there are some troubleshooting techniques that can be performed to see what kind of problems the Dodge A/C system is having. If there are problems in any of these troubleshooting methods, then the compressor should be fixed or removed. Some of the troubleshooting techniques include:

  • Checking to see if the clutch coil engages the compressor shaft when the engine is turned on, which allows the liquid coolant to pump into the compressor.
  • Checking to see if the pulley and the clutch are spinning when the engine is on and the air conditioning unit is turned on to the maximum level.
  • Checking to see if the compressor has a blown fuse, a bad clutch coil, poor clutch computer grounding, or a poor pressure switch that operates the clutch relay.
