Lincoln MKX AC turns on when car is off and shuts off when started on Lincoln MKX

Problem overview

Some Lincoln MKX owners report experiencing issues with their air conditioning systems, such as the AC turning on when the car is off and shutting off when started. This behavior may be linked to a malfunctioning climate control system that randomly activates, similar to the issues reported in the 2013 Lincoln MKZ. Additionally, some owners notice clicking and blowing noises when the AC is activated, indicating potential problems with the cooling fan, especially if the AC is not blowing as cold as it used to. In some cases, troubleshooting is required for one side blowing hot air, even after replacing the actuator. Other reported issues include cars stalling or turning off when the AC is engaged, which could be due to various factors like a faulty idle air control valve, compressor problems, or electrical faults. Owners are advised to inspect these components and seek professional assistance for effective diagnosis and resolution of these AC-related issues.
