Volvo XC60 AC compressor noise issue under the dash on Volvo XC60

Some Volvo XC60 owners report experiencing AC compressor noise issues under the dash, which can stem from several potential causes. These include dirt and grime build-up on fan blades that lead to off-balance conditions and noise. Additionally, some owners have encountered A/C condenser leaks that result in audible noise and diminished A/C performance. Problems with compressor engagement, such as insufficient power to the clutch or relay, may also contribute to noise. Mechanical issues, characterized by squealing or grinding sounds from the compressor, signal the need for attention. Furthermore, a faulty blend door actuator can produce a clicking sound when the air conditioning is activated or when temperature adjustments are made. To resolve these issues, it is advisable for owners to inspect and clean the fan blades, check for A/C condenser leaks, verify compressor engagement, address any mechanical problems, and replace faulty components like the blend door actuator.
