2009 Honda civic purchased in November. The air conditioner seemed to work at purchase but wasn't used because of season. Carfax showed the ac condenser being changed twice ..in a rather short time period. Today the weather is in the 70s+ and the AC blew cold for a few minutes then turned warm. I tried turning it off and waiting but it never turned cold again. I waited a few hours and tried again and it stayed cold for 10 mins or so then back to warm. I've changed the easy things...cabin air filter, ac relay.


Any ideas on what to check or look for before I go to the shop?

 

Since the AC initially blows cold but then turns warm, it could be a few things. First, check the refrigerant level; low refrigerant can cause the system to lose cooling. A leak in the system might be the reason for the previous condenser replacements. Also, inspect the AC compressor; if it's cycling https://tropical-casino.com/ on and off too frequently, it might be failing. Look for any unusual noises when the AC is running, which could indicate a problem. Lastly, consider the possibility of a clogged expansion valve or issues with the blend door. If these checks don’t help, it might be best to take it to a shop for a thorough diagnosis.
