I just bought my used 2004 Audi a month ago and today was the first hot day here in Mass.

For some reason my ECON is always lit and I can't get AC.

I read on other forums that it could be numerous stuff..but how should I approach this?

Some people said to check the fuse...then try recharging the AC..but if the ECON button is on, the compressor wont be on..so how would it take the recharge?

Help.

did you ever fix it?

 

Yeah, I did. I don't have the car anymore though.

So what I did:

1) I bought an AC can from Walmart

2) I added Some of AC can to the AC system inlet line under the hood.

3) I cranked on the AC fan On full blast and realized there was a leak spraying out of the AC condenser. This condenser sits in front of the radiator. I shouldn't have done this since that AC spraying into the air is not good for the environment but I shut off the AC ASAP as soon as I found the leak.

4) bought a new AC condenser and replaced it on the car. It was easy. Didn't have to take front bumper off. Only thing I recommend is buy a pack of rubber orings cause the ones you take off the condenser lines will be brittle and break.

5) refill the entire system with a can of AC and presto, I got AC again and no leaks.

I'm lucky there was no water in my AC system to ruin the system but you should get the entire system "cleaned" before you add AC fluid since it's a closed system and any dirt can decrease the life of the system.

Hope that helps.
