Hello Im Chris and I can assist you. Do you have a test light?
Also do you know that the system is full?
Ok can we run some tests?
I need you to check these fuses for me besides a/c fuse. fan Hi and fan Lo fuse also emis 1 fuse
check emis 2 fuse also they are all in the same box.
I will be on tomorrow at 7 Pm EST. Ill be glad to test it all with you.
Well find it for sure.
Let me know
ok so I guess well chat wed?
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.
if its low it will disable the compressor.
can you read those numbers for me they should both be at around 80 with a/c off.
i see like 0 and -25 that is totally empty and then some
that may be air
yes please do so let me know.
Did you vacuum it?
ok no problem
Hmmm. If you suspect blockage remove a line and blow in air.
35 35 system is low
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.
You are right on one thing. It is electrical. The power is being taken away because of not enough freon.
does your system have a low pressure cut off switch?
the power comes from the switch. Where is the switch you jumped located?
you jumped the br/yel with the yellow wire?
do you have those two colors on the switch?
ok any sensors on the lines on top of the car?
according to my info its a 2 wire sensor
your car is a 2013 with 1.2 right?
OEM diagrams are showing it as a two wire sensor bizzare.
did you disconnect the battery yet?
disconnect both terminals and touch them together for 10 seconds.
make sure they do not touch the posts while doing it.
then try running a/c
see if it starts even for a second
no after u connect it.
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.
can you send me your diagram?
thats just the sensor im looking i had your car as an ls lets see if lt makes difference.
do you have another switch on the compressor. Thats the one i want you to jump
look on the compressor maybe its on the back
the wires going to the back where do they end?
ok tell me what you have on those wires power or ground
i presume that red shoud have power on it.
looks like it goes right to compressor.
if it dont that switch is bad
I dont know what I know is that those numbers 30 and -25 make absolutely no sense. Those guages are no good.
scratch that i get what you mean now.
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.
Sure and thanks. Good luck on this!
