2002 MCS. Short story, a/c blowing warm air. Turned out compressor was bad. I replaced compressor and dryer and took to a shop to recharge. Pressurized the system to specs, still warm. Clutch engaging, line gets cold under the hood, warm air in car. What should I check next? I've seen some things about actuator could be bad. Is there multiple actuators? Do these typically fail? Honestly, I'm selling the car and have two interested buyers but can't get the a/c figured out. Any suggestions? Thanks
