$1100? Yikes!
I still havent had mine fixed for almost 4 years now...I'm afraid of prices like that. Just gotta find someone who can sneak me into their shop and pick up an expansion valve...

busted condenser
First of all thanks to txl146 for making this thread, lots of good need-to-know info here that I did not know. Second, thanks to stikboy9 for the tip about borrowing a vacuum for autozone. Third, thanks to HellaWRX for the tip about rockauto.com, way easier to deal with than classic radiators on Ebay.
I haven't had A/C for at least a couple years now. Hard to say exactly because I just got my license back. I was told last week by the shop that a vacuum test proved I have a leak in the system, and that it is bone-dry. Today my neighbor (big car guy) tried putting freon/die into the system to try to spot the leak. Didn't put a can in before realizing that it was just spraying back out from somewhere in front of the radiator, but the compressor IS working at least. I didn't have a UV light on hand but it was fairly easy to trace the source of the loud hissing sound. Looking closer at the condenser I noticed the mounts at the bottom are both broken and hanging in the air, and the condenser is bent in toward the radiator so badly I can't even pull it forward enough to line up the mounts with the holes. Never noticed that before, but time to get a new condenser. So basically this is my plan, using methods prescribed in this thread, after I just doublecheck with a UV light to confirm it isn't possibly a bad O-ring: 1. Order condenser/removable dryer from rockauto 2. Replace the condenser/dryer, and any O-rings I see, without removing the radiator 3. Get ahold of a vacuum and get any moisture out of the system, while leak testing (or have someone do it for me) 4. Fill it back up with oil/freon mixture BTW, I considered using a can with leak-stop for all of about 5 seconds, as I don't want complications down the road from plugged lines. |

First off, thanks for all the information in this thread! I'm about to replace most of the AC parts on my 02 wrx: condensor, compressor, expansion valve. When I bought the car the previous owner said the compressor locked up on him and he never got it replaced.
I had a question on flushing the system to eliminate any metal particles that are in the lines after the compressor failure. Do I need to flush the system before I install the new parts or can I install everything and have a shop just flush the high and low pressure lines independently? I'm planning on calling a shop on Monday to ask them this question, but I had some free time and wouldn't mind getting started on the job this weekend if possible. Has anyone had any experience with this? Thanks! |

Hey guys, sorry to rebirth a dead thread, but has anybody ever replaced their dryer WITHOUT replacing the condenser? I've just swapped my compressor out and now I'm looking at the thing like: "it's one bolt, surely I don't have to take my rad out???"

About the drier replacement, I've done it before. It can be done while condenser is on the car and fairly easy except installing new o-ring can be a bit of pain.

To the original poster, or others with experiences, how is the aftermarket expansion valve from Autozone working out? My main concern is the fitment.

Reviving a fantastic dead thread.
My compressor clutch wheel sticks. I can drive for anywhere from 5-30 minutes in Florida heat before the compressor clutch sticks and I no longer have AC. If I rev my engine to ~5.5 - 6k RPM, it'll sometimes kick back on. If it is off and I take a wrench to the clutch wheel and just quickly jab it, it unsticks and kicks back on. I am assuming I need to replace my compressor only. Good assumption? |

Put an AC clutch relay in it.
Betcha cold beer that's the fix. I'm partial to a good unfilter wheat beer or a grapefruit radler that ain't too hoppy... |

ac repair
I am inspired by this thread to attempt diy ac repair. Couple of questions to clarify:
- for leak detection better use dye or sniffer? - on 04 wrx receiver dryer can be replaced w/o replacing condenser, right? - what is a better way to add oil in the system, ie from a pressurized can or using mechanical device attached to low pressure port? pressure can may not be precise? - can I just add oil gravimetrically directly in the new part b4 it gets installed - when you vacuum system you only remove refrigerant and not the oil so that you calculate oil needed strictly based on parts being replaced? |

Any chance you can point me to the torque specs for the a/c compressor? Having trouble locating them and starting this job this afternoon. Mine is an O4 impreza 2.5l

Great thread!
Unfortunately the photos seem to be the victim of Photobucket...they're blurry and watermarked. |
