AC blowing warm air, fixed leak and still blowing warm air especially when I come to stop, stop light, or idling. How do I know what is wrong now? Repair shop thinks it could be cooling fan but fan seems to be working fine. Also car is not overheating. How do you know when your DCCV is bad and needs to be replaced and how do you do self diagnostic test on 05 lincoln ls?

Checkfor a vacuum leak first then check to see if actuator is shutting down to warm instead of cold. Sounds like it is. It cold be not charged enough as well. Is it manual or auto temp control.

Car shop flushed out condenser which fixed problem, prior to that husband had cleaned debris between condenser &radiator, cleaned cabin filter, engine filter, and checked fuse yet continued to blow warm air. Thank goodness condenser only needed to be flushed out. Thanks for your info, if have problems again will have items mentioned next time.

I made a mistake yours doesnt' have vacuum operation it's electric. The pic i'm sending is of anactuator and it moves temperature and air in heater. To get to them your dash has to be pulled. But also because yours is auto temp control it needs to be scanned to see what is wrong with it.

Here is a thing I found on how to pick up codes for you car a/c system it will also recalibrate your actuators so your problem with one working and the other not may be straightened out try this anyhow and if any codes get back to me.
