The AC of my 2013 Chevy Spark will not come on. The AC

Customer Question

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?

Expert:  CHRIS ZAPANTIS replied 10 months ago.

Also do you know that the system is full?

Customer: replied 10 months 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.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

Here is the current charge of the refrigerant.
Customer: replied 10 months ago.
Try to jump the pressure switch. No go. Turn on ac, and use multimeter to check for power on the light green wire witl multimeter. No power either.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

Hey if i read those guages correctly im not used to all the different types your low side is reading vacuum and high is empty.

Customer: replied 10 months ago.
I can try to charge it again. It was charged before took it into the shop previously. I have 2 cams of refrigerant, and I can charge it now. Should the power not flowing through the AC fuse in this case as well?
Expert:  CHRIS ZAPANTIS replied 10 months ago.

if its low it will disable the compressor.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

can you read those numbers for me they should both be at around 80 with a/c off.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

i see like 0 and -25 that is totally empty and then some

Customer: replied 10 months ago.
The manifold maybe faulty. Just hook up the guage came with a can of refriegreant. Its over 55 psi
Expert:  CHRIS ZAPANTIS replied 10 months ago.

that may be air

Customer: replied 10 months ago.
Ok. I will vacuum it down then try it tomorrow again.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

yes please do so let me know.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

Did you vacuum it?

Customer: replied 10 months ago.
Its storming out. Won't be able to do it.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

Ok.

Customer: replied 10 months ago.
Still storming today. =(
Expert:  CHRIS ZAPANTIS replied 10 months ago.

ok no problem

Customer: replied 10 months ago.
Vacuuming now
Customer: replied 10 months ago.
Vacuumed earlier today. No leak but ac wont charge. With or without turning the ac on.
Customer: replied 10 months ago.
Vacuum. Low side negative 30. Seemed too low. High side a little less than 0
Customer: replied 10 months ago.
Tried to charge, did not seem to charge, the can did not turn icy. Seemed like low side is blocked.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

Hmmm. If you suspect blockage remove a line and blow in air.

Customer: replied 10 months ago.
Was out this evening. Its my birthday. Will try that tomorrow.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

Happy bday!

Customer: replied 10 months ago.
Turned out it wasnt clogged. Low side 35 psi and high side 35 psi at ambient tempereature 72 degree. I truly think its electrical.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

35 35 system is low

Expert:  CHRIS ZAPANTIS replied 10 months 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.

Customer: replied 10 months 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.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

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

Expert:  CHRIS ZAPANTIS replied 10 months ago.

does your system have a low pressure cut off switch?

Customer: replied 10 months ago.
It has a pressure switch, I tried to jump it but it did not work either because still no power to the compressor.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

the power comes from the switch. Where is the switch you jumped located?

Expert:  CHRIS ZAPANTIS replied 10 months ago.

you jumped the br/yel with the yellow wire?

Customer: replied 10 months ago.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

do you have those two colors on the switch?

Customer: replied 10 months ago.
I cant tell what the colors were. The sensor has 3 pins. It located at the bottom of the car.
Customer: replied 10 months ago.
I jumpes it using paper clip
Expert:  CHRIS ZAPANTIS replied 10 months ago.

ok any sensors on the lines on top of the car?

Expert:  CHRIS ZAPANTIS replied 10 months ago.

according to my info its a 2 wire sensor

Customer: replied 10 months ago.
Nope. It is close to the compressor.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

your car is a 2013 with 1.2 right?

Customer: replied 10 months ago.
Here is the sensor.
Customer: replied 10 months ago.
That is correct. 2013. 12 chevy spark lt
Customer: replied 10 months ago.
1.2
Expert:  CHRIS ZAPANTIS replied 10 months ago.

OEM diagrams are showing it as a two wire sensor bizzare.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

did you disconnect the battery yet?

Customer: replied 10 months ago.
I have not. I can disconnect it.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

disconnect both terminals and touch them together for 10 seconds.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

make sure they do not touch the posts while doing it.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

then try running a/c

Expert:  CHRIS ZAPANTIS replied 10 months ago.

see if it starts even for a second

Customer: replied 10 months ago.
Battery disconnected. Discharged the terminal. Turn on AC without connecting the battery back?
Expert:  CHRIS ZAPANTIS replied 10 months ago.

no after u connect it.

Customer: replied 10 months ago.
Ok
Customer: replied 10 months ago.
It did not even turned a little bit.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

Ok that type of switch you shouldnt have jumped. I dont know why I cant get the right diagram. All mine show a 2 wire switch.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

can you send me your diagram?

Customer: replied 10 months ago.
Diagram.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

thats just the sensor im looking i had your car as an ls lets see if lt makes difference.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

do you have another switch on the compressor. Thats the one i want you to jump

Customer: replied 10 months ago.
I cant find another switch.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

look on the compressor maybe its on the back

Customer: replied 10 months ago.
According to AlldataDIY here are all the switches on this car.
Customer: replied 10 months ago.
That one?
Expert:  CHRIS ZAPANTIS replied 10 months ago.

the wires going to the back where do they end?

Customer: replied 10 months ago.
Just two wire to terminal on the compressor.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

ok tell me what you have on those wires power or ground

Customer: replied 10 months ago.
I wont be able to get to them. I dont have a jack.
Customer: replied 10 months ago.
I wont be able to get to them. I dont have a jack.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

i presume that red shoud have power on it.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

looks like it goes right to compressor.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

if it dont that switch is bad

Customer: replied 10 months ago.
This got me confuse. The gauge from the cannister show low side at 100 psi. The guage at the manifold shows 35psi. That's why I cant get anymore refrigerant into the low side. I cant charge using the manifold because I cannot find a cannister despenser that will connect ro my yellow line on my manifold.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

I dont know what I know is that those numbers 30 and -25 make absolutely no sense. Those guages are no good.

Customer: replied 10 months ago.
Actually it was +35 low and +35 high when i hooked it up this afternoon. I just turned off the valve of the guage, and thought the pressure will stay the same and took the picture.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

scratch that i get what you mean now.

Expert:  CHRIS ZAPANTIS replied 10 months ago.

You want me to opt out maybe someone else can help you better? Im not getting the right diagram on my end which I can not understand why because they are OEM DIAGRAMS.

Customer: replied 10 months ago.
If its ok with you, that would be great! At this point, I think I probably better to take it to the dealership.
Expert:  CHRIS ZAPANTIS replied 10 months ago.

Sure and thanks. Good luck on this!

Customer: replied 10 months ago.
Thank you sir
