Buick Enclave air conditioner not cooling due to leaking rear evaporator core replacement needed on Buick Enclave

Some Buick Enclave owners report experiencing issues with their air conditioning system not cooling due to a leaking rear evaporator core. This problem can stem from corrosion and leaks caused by copper particles from the blower motor. When a leak is detected, it is crucial to replace the rear evaporator to restore proper air conditioning functionality. The replacement process is labor-intensive, requiring the removal of various components, including the rear auxiliary blower control module and blower motor, as well as potentially removing the dash, steering, console, and seats. As a result, the cost of replacing the evaporator core can be significant. If owners notice warm air from their air conditioning system, it is advisable to have the evaporator inspected and replaced to ensure efficient cooling performance.
