My compressor doesn't turn on. I have enough freon and the a/c light blinks several times and shuts off. Can anyone give me a clue on what's going on? I've read about disconnecting the battery and pulling fuses. Any help would be appreciated.

 

Read through this thread. There is a bunch of good info..... GOODLUCK!

Please check and post all of the DTC codes that are stored in the DIC. The HVAC system has diagnostic codes assigned to it.

I checked the codes and the HVAC brought up two. They are: BO361, and BO441. Are these correctable on my own? I also had a couple of more codes that came up that I'm not familiar with. They are in the 10 PCM. These are PO654, and P1571. What do these codes mean. Any help would be appreciated.

Here is a really cool web site that will ecplain all of the codes:

This is the absolute best C5 Code web site!!!

They are: BO361, and BO441.

B0361 is Left actuator feed back short to ground.

B0441 is Left actuator is out of range.

10 PCM. These are PO654, and P1571

P0654= Engine speed output circuit On that one check fuse. It is in the Under Hood electrical center. Fues#19 (Eng Ign )

P1571= ASR Desired torque circuit. Some of the others may be causing this one.

Clear them all and see if any come back.
Repost the results.

Thanks for the info. I'm going to check the fuse and see if it's blown.

 

My guess is a pressure issue between hi and low side. Or, refrigerant level has caused a sensor to cut everything off so no damge is done.

I JUST had this issue today on my kids car -An Eclipse - didn't seem to be cooling very good. Got the gages out, connected it up, added just a squirt of 134 in. As soon as that hit the sytem, the A/C (and fan) simply shut down.

Took up to the local garage. They have this fancy computer they hooked up to the hi/low side and it reads pressures and how much refrigerant in the system. In putting in 134, with no means of measuring how much, in just a few short seconds it shut down. The PLACARD clearly states the entire system takes 15 ounces (less than one full can of 134 from Autozone), nor more, no less. I had about 22 ounces and they said it was a miracle the condenser didn't blow.

Yep, its that fricking complicated now. Have someone hook it up to the computerized system and let them check it. Your electrical system is most likely perfectly fine, and there is no way any gadget can test the pressure and the amount of 134 in the lines, even if it isn't turning!

My expereience today only cost me $25 - Nice guys understood the stupidity of a wrench twister and hammer banger.
