Condition

Some customers may comment that the vehicle’s A/C is not cooling or is not cold enough and/or the A/C compressor is noisy.

Correction

Do not replace the A/C compressor.

For concerns of A/C system noisy during slow parking lot maneuvers, replace the HVAC hose with suction line (P/N 20757021 or aftermarket equivalent). For concerns of A/C not cooling, diagnose using information found in SI.
