Airconditioner HELP
So far I have had 3 men working on my aircon. They are all stumped as to what is the problem. It is working, however it cuts in and out at 1 minute intervals. Has anyone got this problem ???????? or had it.
( this has nothing to do with temp gauge) pleaseeeeeeeeeeeeeeeeeee HELP it's hot here in Queensland. JoAnn |

Now that i think of it, I beleive ours did that as well and our techs were confused as well. The only problem they could find were some small holes in the compressor. At this point nothing has been done to the system except we put in Duracool with some leak sealent. We didn't replace the compressor (didn't have the money at the time) but i'm thinking about it now. We just removed the belt. I would LOVE to get it up and running again. But from what i remember it would go on and off all the time. Pleeese let me know if someone knows why this is happening.
Thanks |

My guess is either moisture in the system and/or an improper amount of refrigerant.

According to my service manual, if the outside temperature sensor detects temperatures lower than 10 degrees centigrade, the anti-freeze protection mechanism will cycle the compressor on and off. You should check your outside temperature sensor - does the temperature display correctly when the "OUT. TEMP" button is pressed? Jason.

I have also found out that the output of the Evaporator Temperature Sensor can also control the compressor on-off operation.
Unfortunately, the output of that sensor cannot be read easily - unless you have a Subaru Select Monitor! The other device that could affect the compressor is the Trinary Switch, located on the left-hand side of the condenser. This switch automatically stops the compressor from running if there is too much, or too little refrigerant in the system. Jason.

The Ambient Sensor is on the bonnet lock support, at the front of the radiator. If it is open circuit or the wiring is disconnected or high resistance, the auto amplifier will be signalled that the temperature is below 10* C and the clutch will cycle continuously by way of protection against freezing. At an ambient of 25 Deg. C it should measure 3,000 ohms and at 30, 2,400.

Air con trouble codes.
Hi JoAnn,
I think it would be best for you to pull the trouble codes, from the air con computer, and tell us what the code number is. We then may be able to go further with finding the fault. The process for posting the codes were in the set of sheets that I sent you. If you have given them to the air con guys, you can see them again here. http://www.subaru-svx.net/photos/user.php?oab_au|35851 Just follow the sheets to have the code number displayed on the temp dial. Also you say that "it cuts in and out at 1 minute intervals", What is it that cuts in and out, Is it the air con clutch, the cold air, or the fans Harvey.

Air con
Thankyou for all those who have been helping Joann. I am one of the People who have been working on it and this is what I have found to date...... Have followed procedure for fault codes and no code was recorded, Have checked all gas levels and Pressures and all are fine have even disconected trinary switch and bypass switch and still the same. Of the 3 people that have worked on it ....The electrician seems to think there is a problem inside but did not go into detail as I dont think he knew exactly what it was but he did check out all fan and a/c wiring, myself thinks the compressor is faulty as in internal overheating, and the other tech thinks it is a control panel. The biggest problem we have is limited parts and can be expensive for new parts. The svx is not that common either which makes it a bit harder I think the last one I saw was about 3 years ago........... One of the most common things over looked with cars that are getting older is cost, Eg. 89 EA Falcon can be bought for $500 to $2000 cost to repair A/C is Compressor $1200 Evap $740 Cond $500 TX $250 the list goes on (these prices are labor gas part etc) The other problem we have is what you fix today say Condensor,Then Evaporater or Compressor is not far behind from failing as well. Some Compressor's Eg. 05 MG can cost $5000. I havent rang Zupps yet to see what a SVX Compressor would cost but I would hate to think. As far as second hand, I have seen a customer take a compressor back 5 times to the wreckers and sure they will happily give you another but they do not pay for labor and gas.
He had to wear that 5 times until it was right. (and no you cant see how good they are just by looking at them, they must be connected and running just to see if they pump or are niosy). So where does this leave Joann ... If anybody has a control panel to lend her that would be great, This would eliminate that one. But we do thankyou all for your input any other info would be good. |
