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.

Mine did that and it turned out to be the evaporation temperature sensor.

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 !
