Customer Question
The AC of my 2013...
The AC of my 2013 Chevy Spark will not come on. The AC switch by the central console turn on (green LED) came on. But no power from the Fuse going to the compressor to engange the AC clutch and turn on the AC compressor. Still no power after changing out the fuse.

Hello Im Chris and I can assist you. Do you have a test light?

Also do you know that the system is full?

Ask Your Own Chevy Question
Customer reply replied 1 year ago
I used the test light to test the power and see if power flew to the fuse, and then to the compressor when I switched on the AC. Yes, the system is full. The Mechanic at the Shop checked the system and used the Test Light as well and told me that the AC Controller Unit at the Central Console link: http://mlm-s2-p.mlstatic.com/2011-chevrolet-spark-control-ac-95979291-904211-MLM20521535353_122015-O.jpg need to be replaced. I doubt it. He is just an independent mechanic that owns his own shop.

Chevy Mechanic: CHRIS ZAPANTIS,

35 35 system is low

Ask Your Own Chevy Question
Chevy Mechanic: CHRIS ZAPANTIS,
 replied 1 year ago

You probably cant get it to fill with enough to stay running. Power up that compressor to get it to accept the charge. This is why we use machines to charge a system it will pump it in without waiting for the suction side to draw it in.

Ask Your Own Chevy Question
Customer reply replied 1 year ago
Too low to kick start the compressor? But, it won't take any more refrigerant. I will have to recover all the refrigerant, vacuum if I need to find out if the line is blocked.
Chevy Mechanic: CHRIS ZAPANTIS,
 replied 1 year ago

You are right on one thing. It is electrical. The power is being taken away because of not enough freon.
