So, saw in several comments to keep from replying multiple times: The condenser was free of debris. No debris was built up between the condenser and radiator. None in front of the condenser. Both cooling fans ran and were running at full speed when A/C compressor was engaged.

Just replaced our compressor. Had replaced three condensers previously, Subaru paid for the new compressor since the earlier condensers had probably trashed it. They paid for two of the three condensers.

@kevinm5177 11 месяцев назад

@@brannnnnnn2017 Forester, very early production. First condenser was just a little out of warranty. Someone told me to call Subaru of America and complain. I called, spoke with a very nice person. They paid for the entire bill AND sent me a $300 Yeti cooler! Very stoked! About a year and half later, second condenser. Covered again! No cooler😔 Then I had to take it back as they didn’t tighten a bolt and it lost charge. Last condenser was about six months later. They claimed a rock hit it ( yeah right). Then it started doing the usual thing (drivers side no cool), ended up being the compressor this time. I told them it was from all the crap in it from the condenser failures, and the dealership took care of it. Not sure if they got SoA to pay or not.

Been following for a while now as I have found you to be the best source of info for helping me work on my 7th and 8th subaru. My 2008 LLbean falls into the poor AC category. Only worked great when I first got it. Had it at the dealership here in central NC once for this and they said it was fine. Well, it didnt feel fine. Still doesnt feel fine, so, gonna go through and replace the condenser, evap, the expansion valve, cabin air filter (for the 4th time) and was wondering if I should worry too much about the compressor since it always seemed to function fine.

@MrSubaru1387 11 месяцев назад

Depends on what you find inside the system once you open it. If there’s a bunch of dark oil and metal particulates, that compressor is toast.

@imagumby7713 11 месяцев назад

Or, the Denso 4711055 compressor at RA for 278 might be a good investment for a car with 150k?

@RATCHETMAN1001 Месяц назад

i also like to get a veh stabilized before looking at pressures only. a lot of heat load and latent heat throws off pressure readings.100 degrees inside car blowing over evap is going to change low side pressures up . but i agree with the black, every thing should be shinny in a good system.

@RATCHETMAN1001 Месяц назад

when you see the black its been low on refrigerant. Thats what destroys a compressor very fast, all the oil leaves compressor and goes to evap and the gasses going back to compressor is hotter and over heats it more. take some temp measurements on the line from evap to compressor when you get it fixed and check lo pressure and convert to saturation .

Excellent video, AC problems can be as simple as complicated. At that point there is no other alternative than to remove the compressor and check the oil, if it comes out dark, it is a sign that the compressor is bad and the condenser must be changed because everything must be contaminated, etc. What state are you from, your language is very clear, I understand you practically everything.

Sometimes just cleaning the condenser/radiator helps a little bit I just did my Legacy using some evaporator coil cleaner and I’m surprised how much cooler my AC got, I don’t have a gauge for my high side I ended up using that AC pro but I put very little in the car, I know the right way to do it is have not only the low side but the high side what I’m gonna do later take it to my local shop guy and have him put the machine on it put a vacuum on it pull it and recharge it with the right weight At the end of the summer

@MrSubaru1387 Год назад

If you are low the ac compressor will short cycle. It’s not good for it and can lead to very expensive repairs if the compressor comes apart because the trash gets spread throughout the system.

my 2014 forester AC is absolute garbage. I imagine it's something complicated like this situation, the dealership both times has told me it's working perfectly but we can experience AC at full blast on an 80+ degree day and we are still sweating in the front seat. There is no way this was the intended design. It used to work when we bought it, but it's been getting slowly worse each year.

@VH-lp4ll 4 месяца назад

My 2016 Forester’s AC is acting funny. The AC indicator light blinks but then goes dim, no cold air. Sometimes I hold the button in, AC works but not always. It kicks on sometimes but after a little while, I get warm air. Sometimes when I’m on the highway and this happens, I start getting cool air again after a little while. I’m just at a loss. Some say it’s a connection issue to a fuse to I have no f’n clue.

@AussiB-rb6dy Год назад

Great videos and channel to watch and I love my WRX. When the AC system is not over charged high, head pressure most of the time is caused by a condenser problem (dirty outside of the condenser, dirty inside the condenser, blocked condenser or cooling fan is not moving the air across the condenser) that is preventing the transfer of heat from the refrigerant gas to atmosphere . AC systems need a small amount of oil to lubricate the compressor and some of this this will travel with the refrigerant around the system seeing a thin film on the Tx valve after years of use is not a surprise. The black in the oil can sometimes come from the breakdown of natural rubber components that release small amounts of carbon into the refrigerant.

@brianmontgomery2779 Год назад

Would the diagnostic process be similar on a 2014 legacy? My independent shop has replaced the leaking o-rings and recharged but the ac just seems to struggle if it’s been heat-soaked sitting out in sun. Once at highway speeds for a while it cools off. And it cools fine if starting out from in the garage/not sitting in sun.

@Mike_44 11 месяцев назад

This video came right on time.. My ‘05 OBXT engine slightly overheats ONLY when the A/C is on. I noticed after turning on the A/C and the fans turn on, they only stay on high, rarely going back to low speed. The A/C is not blowing cold as it used to either. The engine doesn’t seem to overheat when the A/C is off. I also heard a squealing/pulley like noise the other day, possibly the A/C compressor. The slight engine overheating only occurs on heavy local traffic, not during Hwy driving. Could a bad A/C system put strain on the engine to where it overheats?

@jhoelt2922 Год назад

Thought my ac was failing on 09 legacy 3.0r but I believe it might be the drivers temperature actuator. I’m hearing like a clicking noise in the dash and the passenger side blows cold. Is it possible to replace it without removing the dash?

@bradh6185 9 месяцев назад

I hear Subaru air conditioners aren't that great to begin with, especially compared to Chevy, Ford, and Toyota. I'd hate to buy a car and be told the reason the a/c isn't keeping you cool is because it's hot outside.

@bmc5180 9 месяцев назад

@2:08 You mentioned that the customer reported occasional squealing sounds from the compressor upon startup. What could cause this? My AC system functions flawlessly (in the heat of Central Texas) but it squeals every time I start the engine from cold. The squeal goes away within 30-60 seconds, but it happens every time.

@rosspetersen1879 Год назад

I've got an 06 Outback 2.5i that has some AC issues. At idle it hardly puts out anything cool out, but once you get up to highway speeds it cools off just fine and ices over if you're on a long trip. I changed out the expansion valve and condenser/filter last year and had a shop pull the refrigerant and fill with new, no change. The old desicant bag was pretty oily/metalic-y looking so I'd guess the compressor is taking a dump or like you said there's a blockage somewhere/multiple places. Does that sound about right for a bad compressor?
