A/C not working

[CLAIRE10]

I have 2015 Tahoe LTZ maybe 4 weeks ago alternator went out and killed the battery. Put new alternator in replaced the battery. 2 weeks later thermostat went out didnt have heat replaced that. Now my A/c is not working checked the freon it was over full let some out to where it is supposed to be. Switch it from hot to cold and the heat gets hot but when you turn it on cold you can here the compressor turn on but no cold air. Anybody have any suggestions

It could be that one or more of your blend doors is not operating correctly. A quality bi-directional would help you troubleshoot this issue and to test all of your blend doors.
