No cool air coming when A/C turned on. Coolant level good, controls all functioning - just get hot air! ---

About all you can do yourself is to make sure engine compartment fans are working, nothing is clogging the free flow of air through the A/C condenser (near radiator), and if there’s an hvac air filter in the passenger compartment, make sure that is in good condition. Beyond that a well recommended AC specialist shop will check if the A/C compressor is turning on, the various refrigerant pressures are correct, and that the hvac air-pathway doors are working. If you were hearing any unexplained clicking noises from under the dash before this symptom, pretty good chance one of the door actuators has failed. ---

This could be a possible cause. if it is it will be a free repair. [MC-10188184-0001.pdf (nhtsa.gov)](https://static.nhtsa.gov/odi/tsbs/2021/MC-10188184-0001.pdf) ---

Interesting that a batch of condensers has internal corrosion. OP needs to have system inspected to see if there is a leak of r134a. And if so, where is leak coming from. ---

Maybe the same company made the GM truck condensers also, I know I replaced a lot of them around 2014-2018 time frame… lol " _In a November 2017 mailing to owners GM said the condensers may have a condition where **thermal cycling on the combination transmission fluid/oil and AC condenser cooler creates a crack that may allow refrigerant to escape**. This condition consequently may deactivate the AC_" But you are better off taken it to a qualified AC tech and let them check it out… it could be as simple as a blend door stuck (for whatever reason) to something major…
