AC blows cold then hot
The AC blows really cold then, after a few minutes, blows warm. When I press the EC button and then turn EC off, it'll start blowing cold again, for a few minutes. That doesn't always work, though.
Seems like the compressor shuts off and when I press the EC button on and off, the compressor turns back on.
I replaced the compressor. There are no leaks in the system.
Thanks for your help.

The suggestion would be to pull Climate Control Diagnostic - and post the results here - one common cause "could be" need replacement evap temp sensor - Climate Control codes will outline your specific issue.

Do a search and pull diagnostic.
Based on symptoms - the profile does fit failed Evap-Temp-Sensor.
The good news - the China knockoff part seems to work just fine for $14 - see Amazon link below:
Forum search should bring up replacement instructions - from in the cabin - once you know where it is it's straightforward - having a small flashlight at hand helps.
Keep the beat !

No need for crystal-ball guessing when in just a few minutes you can do full troubleshooting with tip of your finger.
Post the results here and we help to interpret them.
