I have a 2008 Saturn aura. The AC compressor was replaced.

Customer Question

I have a 2008 Saturn aura. The AC compressor was replaced. The plug was melted so they slice the wires and put another plug in its place. Jumpstart the fans so the fan works. checked and changed fuses those were good. AC still does not work. Heat does not work unless I set it to 89°

Hi Im David, thanks for visiting the site. what connector was melted? the plug to the compressor or the plug on the compressor?

Customer: replied 7 months ago.
Both. The plug on the compressor was melted onto the plug that connects to the compressor. Replaced compressor and plug that connects to compressor. wires where sliced on the old plug to the compressor
Customer: replied 7 months ago.
To replace the AC clutch coil connector
Expert:  david craig replied 7 months ago.

ok. did they recharge it with the proper amount of refrigerant? im assuming they did

Expert:  david craig replied 7 months ago.

also since the plugs were melted, did they check the fuses?

Customer: replied 7 months ago.
They thought is was the fans so they jumped started it they work.
Expert:  david craig replied 7 months ago.

they thought it was the fans causing the ac not to work? so the compressor never engages right?

Customer: replied 7 months ago.
Right
Expert:  david craig replied 7 months ago.

here are some fuses to check. any that deal with the ac, climate control, ac clutch, hvac contol, etc....

Customer: replied 7 months ago.
All fuses were tested and replaced still no power. When AC button is pressed from inside of car nothing happens
Expert:  david craig replied 7 months ago.

ok. it should have a relay for the cutch. let me find it for you.

Expert:  david craig replied 7 months ago.

ok. theres a relay for the ac clutch in the fuse panel under the hood. pull that relay. do you have a multi meter?

Customer: replied 7 months ago.
It's good I also checked one that has the same numbers
Customer: replied 7 months ago.
They both read 00.1
Expert:  david craig replied 7 months ago.

00.1 what? volts?

Expert:  david craig replied 7 months ago.

check the base for voltage. not the relay.

Customer: replied 7 months ago.
Okay
Expert:  david craig replied 7 months ago.

one slot should have 12vdc at all times. one should have 12vdc with the key turned on. the other 2 shouldnt have any voltage

Customer: replied 7 months ago.
12.57 off
Expert:  david craig replied 7 months ago.

ok. does another slot have any voltage with the key on?

Customer: replied 7 months ago.
11.89 key on
Expert:  david craig replied 7 months ago.

ok. good. now leave the key on, install a jumper wire between the slot with 11.89vdc and one of the other slots that dont have voltage. have the ac turn on while doing this. let me know if the compressor engages.

Customer: replied 7 months ago.
Nothing happen
Customer: replied 7 months ago.
it clicked
Customer: replied 7 months ago.
It's not running but it clicks
Expert:  david craig replied 7 months ago.

ok. with the jumper in, can you check for power at the clutch connector?

Customer: replied 7 months ago.
Inaccurate readings. At times it read .89 but mostly it didn't read at all
Expert:  david craig replied 7 months ago.

ok. now put the jumper in to the other slot that didnt have voltage, leaving the one side alone that has voltage. check it then

Expert:  david craig replied 7 months ago.

any luck?

Expert:  david craig replied 7 months ago.

do you still need assistance?
