Scribbs Posted June 26, 2019 Share Posted June 26, 2019 Can anyone assist in possibly diagnosing this problem? I'm thinking the AC compressor is bad. Whenever the AC is on it sounds like a jet engine under the hood. Lifted the hood, and the noise is coming from the compressor area. I made a short video of the noise. I'm still getting semi-cold air. https://imgur.com/a/QghqFuR 0 Quote Link to comment Share on other sites More sharing options...
DavidOPS Posted August 19, 2019 Share Posted August 19, 2019 I am having the same problem. I would also like to confirm if this is a failed compressor or another issue. 0 Quote Link to comment Share on other sites More sharing options...
anbowden Posted May 20, 2020 Share Posted May 20, 2020 (edited) I'm also having the same problem. My local Ford dealership diagnosed it as a high side line leak which resulted in compressor damage. The estimate for repairs included a new compressor, condenser, and drier (maybe a new evaporator too?) which came to $4000! A new electric compressor is ~$2k. So since the repair is more costly than the value of the car, I've been considering getting a junkyard compressor and installing it myself. I understand the contamination of PAG oil in a POE oil system, but can I get a local shop (without a dedicated POE machine) to hook up their R/R/R machine simply to evacuate the remaining refrigerant? And then later after installing the new compressor hook up to put a vacuum on the system? Edited May 20, 2020 by anbowden 0 Quote Link to comment Share on other sites More sharing options...
anbowden Posted May 22, 2020 Share Posted May 22, 2020 Does anyone know if I can use a shop a/c recovery machine to hook up to a hybrid a/c system simply to evacuate the refrigerant without fear of contamination? 0 Quote Link to comment Share on other sites More sharing options...
anbowden Posted May 24, 2020 Share Posted May 24, 2020 I took my car to a buddy who has a small shop with an a/c r/r/r machine. He cleaned the r/r/r lines before hooking up to my car and used virgin R134A when recharging. After going through his standard procedure he concluded I was low on refrigerant and there probably is a leak, but not on the high side. He recharged my a/c system and now my a/c is working again. One interesting observation is the compressor is running much quieter now, probably as quiet as when new. I read one possible result of PAG contamination would be voltage present on the compressor body (obviously a shock hazard). We had a multimeter hooked up with one lead on the a/c compressor body and the other lead on a ground. We never saw a change from before hooking up his r/r/r machine until after the full a/c service. I'm not sure if this was a valid test, but it was the best I could come up with to get an idea whether my a/c system was contaminated. 0 Quote Link to comment Share on other sites More sharing options...
