Air conditioner problem. It’s been replaced 3 times and is still bad.
What is your question?
A/C stopped blowing cold air, would randomly go from cold air to warm air. Took it to my small independent mechanic. He replaced it. Couple weeks later stopped blowing cold air again. Took it back, he replaced it again. Manufacturer of A/C covered cost. Couple weeks later happened again. Replaced again. Now it’s happening again. Wondering if it could be something in the control panel? However, a strange thing is that it will go from blowing cold air to hot air without me even touching the control panel. Any suggestions to what could be causing this? My mechanic couldn’t figure it out.
What makes this problem better or worse?
Nothing

Hello, when you say, "he replaced it" - what component do you mean? The compressor?
I feel like you need the assistance of a higher skill level technician with proper test equipment to find out what is going on with your vehicle.
Air conditioning problems can originate by one of the following general areas:
1) A problem with the refrigerant system. Meaning, the refrigerant used has escaped and there is not sufficient refrigerant to pressurize the system properly, resulting in hot air. When this happens, the system must be checked for leaks, the leaks repaired, and the system recharged.
2) A problem mechanically or electrically with the under hood components. If the compressor has failed, it will not allow the system to operate. Further, if the system becomes contaminated with debris from a failed compressor, this can be even worse. Electrically, the coil of the compressor may not be working properly, or a cycle switch could fail preventing the system from operating. If your condenser fan is not working, the system may not work properly also.
3) Climate control problem inside the vehicle. If the system that operates the heating, ventilation and air conditioning system fails to operate properly, then the under hood components may not be turned on or off properly, keeping the cold air from being produced.
Only testing these systems will yield a direction and an eventual result.
