Default AC stopped blowing cold

So I've got a little over 50k on my '06 and the AC recently stopped blowing cold air, not good in July. I wouldn't hesitate to go into Subaru to get it checked out but I've got a load of mods on my car, namely the 18G along with a host of bolt-ons. My warranty is until 60k but do I need to go to stock if I want to take it in? Will I be voided for my unrelated mods? Please help since 90+ heat and no AC in a 3 year old car is not ok. Thanks.

The A/c is only covered in the Basic 3/36k warranty unless you have an extended warranty.

With all your mods, there is a chance you may have bent a A/C line in the process of installs or part removal. There is also a chance of a pin-hole refirgerant leak that can happen in a line overtime.

The above issues can be fixed by either having the system professionally charged for 99-130ish at most shops or do it yourself. Buy the fill kit (with the green indicator fluid), and top the system off, ensuring that you don't put to much refrigerant into the system. Some of the nice kits have pressure gauges to measure this.

If you do have a leak, the green indicator fluid in the refrigerant will seep out of the hole, so you can find the leak and replace the line.

Thats one problem/resolution, the next could be a bum compressor. Turn your A/C on and listen for the compressor to crank over, check the belt tightness, etc. Those are prone to failure as well, since they take some abuse over time.

Good luck!

99% of the time the refrigerant leaks through the shaft seal of the compressor.. not a whole lot you can do there. I'm sure the stealership will recommend to change the compressor though. Just top it off with some R134a and you'll be good to go.

That's funny, I see A/C lines, evaporators, o-rings and condensers leaking more than a Compressor or a bad compressor. I would say maybe 5% of the time it is a Compressor.

The shaft seal leaking is part of the design. They are wet seals (if they are anything like big compressors), so refrigerant/oil can leak back through in certain running conditions. Lines/fittings are the first thing to check, you will know if a compressor is going bad, because it makes all sorts of funky, 'im not running right' sounds. I have seen many compressors go bad on many cars.....they are heavily abused in day to day running, specially in areas of 90+ heat.

Not to go OT on you guys, but you seem to know quite a bit about a/c systems. Is it true that current systems go bad because Freon had an oil in it that kept the rubber seals from cracking? Now with the R134A, the seals/gaskets fail more frequently because of the make up of the R134 vs Freon? I'm not having any issues with mine, but I'm curious since I heard someone saying that before?

There will always be a little bit of oil within the refrigerant mix, because of the system design, the compressor has some oil leakback either through seals or through fluid transfer.

As for seals cracking, the seals are material compatible with the refrigerant within the system, so I am not sure why any would 'crack' or become crappy, other then from wear/tear over time.

New refrigerant cooling efficiency is however a little less then using older less enviromentally or human friendly refrigerants such as R-12, but 134A, 404A, 410 etc etc, are just mixtures of the old stuff that are now better for mother earth. However as technology advance, better refrigerants should hit the market (haha everyone hopes). Although the big push now is natural refrigerants, I think some Mercedes or BMW uses CO2 for car A/C. Some serious pressures involved though.

Thanks much, Sleepr! I appreciate all of the info and now feel a bit more knowledgeable

Haha, no problem, hopefully it is all at least 99% correct

Same thing just happened to me 2 weeks ago. The dealership said a rock hit the compressor and broke it. I had it replaced under warranty (Gold Plus extended luckily!)

That should have technically been covered by your insurance, not the extended warranty....hopefully Subaru doesn't ask for the condensor back, otherwise, the dealership might be calling you to pay for the repair.

Honestly, the dealer should eat that repair. That is their mistake and fault, not the customer. You never know with some of them though.

That is true...and I agree. But it all depends on the type of dealer they are. They MIGHT call him and ask him to pay for it, but he can fight it.

Yup.

I think we got 2 outbacks from you guys. I know they said Mastro on the back. Surprising as the furthest south we have gotten cars were NC.

It could just be you needing to recharge your freon. Do you use the AC a lot? It's still blowing hot air you said. Also, when the AC starts to go there are a couple symptoms.. The air not being as cold and taking a long time to get cold.

If I had known they were headed your way, I would have put a 'love note' in one of them....
