Reasons a Chevrolet Malibu AC Isn`t Working. The most common reasons a Chevrolet Malibu ac isn`t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor. You may not realize there`s a refrigerant leak until the air conditioner stops blowing cold.
If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.
The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.
Why do I get hot air from my Malibu A/C? An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.

Overheats When Blowing Warm With Heat & AC But Not When Blowing Cold AC
ANSWER : Hello, thank you for writing in. There are so many different codes being triggered, that it is unlikely all of these systems are having issues at once. We need to focus in on the fact the engine is overheating at all. You will want to check the level and condition of the coolant and the overflow tank. If the level is full then you may have an issue with the thermostat, radiator cap, or water pump. These can all be tested and changed relatively easily. If the main cooling system is okay, you will want to look into the heater core and climate control module. For more diagnostic help, contact our service department to schedule an appointment.

ANSWER : It is possible that you have a leak in the AC system. There are pressure switches that will turn off the compressor if the pressure is too high or too low. The low refrigerant level could cause the AC compressor to cycle on and off. If you would like to have this done, a certified technician from YourMechanic can come to your car’s location to diagnose the AC system and make the correct repair.

AC stopped blowing cold air
ANSWER : Hello! There are a few potential causes of your problem that I recommend inspecting. I would first check the refrigerant levels of the system, to ensure that it has adequate pressure. If the pressure is low, I suggest having a technician inspect the system for leaks; I think this is unlikely, since the AC stopped working so suddenly. The most likely case is that there is an electrical issue, such as a blown fuse or open circuit, although I would also recommend checking the performance of the AC compressor. Please keep in mind that the Federal Government requires all AC work or repair to be done by an EPA-certified technician. YourMechanic can send an EPA-certified technician to the location of your Expedition to inspect your AC system, and recommend the best path to repair.
