My AC compressor blows cold air, but sounds like a Yeti, it's much louder then my exhaust, and I have a GMMG. During the winter months I just pull the AC relay, but it's too damn hot to do that now, so I want to replace it.

How hard is it to replace? What is involved? I've done the A4-M6 swap, LS1 brake upgrade, and replaced the water pump and power steering pump, so I know my way around this car.

What things could I do myself? What would I need to go to a shop for, and what is the going rate for those services uaually?

Sorry for another AC post, I know this time of year they're all over the place.

 

I got mine out with everything on there. Just takes a little time to manuever it out I am sure you can get it out without removing anything else

 

How do I go about uncharging/charging the system?

 

Gotta take it to a shop to have them vaccuum the remaining refrigerant out of the system. It's illegal to vent the system into the atmospehere (not hat anyone would be able to catch you doing it).

 

Haha no kidding huh. Although I would have it vaccumed anyways cause you will need that done before you refill it.

 

Is recharging the system a simple process or is that something I should have done at a shop?

What's a reasonable price for a discharge/charge?

 

try putting a can of ac oil in the system its 5 bucks thats probibly your problem and your ac should be the new r34 does not harm the ozone .the compressor will get load when low or no oil in system

 

I would have it done at a shop. Just a little easier for them

 

My Haynes manual doesn't say a damn thing about AC oil. How do I check the level/add if needed?

 

they sell it next to the r34 u ahve to have oil in the system ..put it in just like r34 on low side its to easy .crank car turn on ac hook up hose on low side close to the dryer with ac on high it will suck it in when can is empty its done its like 4 ounces or so

 

It's R-134a... not R34. And the oil you would use is called R-134a PAG oil. I don't think that's gonna fix it though. Oil doesn't just disappear unless there is a leak, and if there was a leak, he wouldn't have any refrigerant. And yes, the R-134a is still illegal to vent into the air.

 

thanks for the info, I'll probably just replace the compressor to be safe
