My wifes A/C on her '01 LX stopped blowing cold a couple weeks ago. I hit the shrader valve on the low side momentarily and hardly anything. I've put freon in it since then, but it will all leak out within 1-2 days (compressor kicks back once I start adding freon).
I ran the AC diagnostic code test as well. Turn the ignition to ON, then hold reciruclate and AUTO buttons at the same time. I got codes 17, 19, 26, 37 and 47. I've tried to find a list of the codes, but could only find a few of them.
Anyways, I went to harbor freight to get a Freon Leak Detector to see if I could figure anything out (going to take it back, pretty useless). I traced through the AC lines in the engine bay and then down along side the passenger side frame rail and couldn't find anything. I know most line leaks I've read about are usually the rear AC lines under the frame rails or under the muffler heat shield. This truck is completely rust free and I couldn't find any areas where it looked like a line could have gotten corroded.
I looked at the High pressure line that runs on top of the radiator/fan shroud and noticed some slimmy/greasy spots on the hardline and where it connects to the rubber hose as well as the top of the fan shroud. See pic:
Then I looked down at the compressor, and it looks like there's a leak around where the High pressure line connects to the top of the compressor. The liquid is green in color. My first thought was maybe a coolant leak, but my coolant is Toyota red. I'm guessing the green color is from some kind of UV dye that was introduced to the system at some point? See pics below:
So, my best guess is I need to replace the long line/hose that goes from the compressor up and over the fan shroud and connects close to the passenger headlight (i believe it goes into the condensor?) Does anyone have the part number for the line? Also, does anyone else have any idea what the diagnostic codes are? Sorry for the long post, but I really appreciate the help!
