The problem: In affected vehicles the air conditioning is noisy, does not cool or is weak. Symptoms could be intermittent. This condition could be due to a faulty air-conditioning compressor or regulating valve.
Corrective action: Dealers will replace either the air-conditioning compressor or the regulating valve, flush the system of contaminants, recharge the system and test for leaks. This is a labor-intensive operation; plan on leaving the car for up to two days.
