ugh, my AC stopped working last week, on the way back from a trip to Canada.
Everything was great and 'cool', until I was a few hundred miles away from home on the highway. I noticed it started to get warmer in the interior. I thought maybe it was getting warmer as it was sunny, around 1PM with the sun moving around its highest point in the sky. So I lowered the temperature, eventually all the way to "LO" with warm air starting to come out the vents.
205k miles
Got home and put some AC manifold gauges on the AC lines, and they show around 140psi low and high pressure sides with the compressor off obviously. So there is refrigerant and no leak. Fans turn on when I press the 'Auto' button+'Lo' temperature setting. Swapped the top "snowflake" relay on the box with another one, no go. Read the A/C clutch circuit procedure on the FSM and put a jumper wire on the pin slot 1 and pin slot 2 on the "snowflake" relay. No compressor movement.
So I am assuming and hoping the clutch mechanism parts is no good anymore. I never heard any sound prior to noticing the AC no longer working, and I can easily spin the front of the compressor with out feeling anything rough.
Planning on getting the refrigerant sucked out, replacing compressor and condenser. The fins on my condenser are pretty beat up from road debris, and the reciever/dryer should be replaced when opening the system. Might have to add more parts if the compressor oil has debris or any other evidence shows up.
