Hi
I know very little about working on cars. On my blazer the a/c went out about a year ago. Got it recharged worked good for a couple of months and then back to hot heat. Got it recharged and checked for leaks. No leaks were found and the same thing happen after a couple of months it went back to hot air not cold. Everything works but the cold air. Some one said maybe fuses, but they were checking and all were good. Any ideas or anything, please?

Sounds like an extremely slow leak. Check your pressure, if it is low again you will have to get the leak fixed before it will work properly.

You have a leak, ask them to add UV dye to the fluid when recharging it.

They can then use a blacklight to see the leak in the dark.
