    AC Pressure Relief Valve woes

    Numbers now are around 77 degrees and 55/270. I tested several times while bringing the pressure down and it got down to around 75 or so but never got below that. It’s 115 out today… Here is a recording of it https://drive.google.com/file/d/12k_ig7mGIer-SO1FvZ9TXutHqWPCwfRP/view?usp=drivesdk

    AC Pressure Relief Valve woes

    They are VERY high - I stopped at 60oz and let it run for a while. It was still pretty high and wasn't blowing very cold so I finished adding the extra 2oz to see if it would blow colder. At 60oz, and not blowing cold enough, I would think that if adding more didn't help, then taking more out...

    AC Pressure Relief Valve woes

    With 110 degrees outside it is 70/390 stable blowing out the vents at about 70 degrees. If I increase engine RPM, it cools down to around 65ish Turn it off and it evens out at 150

    AC Pressure Relief Valve woes

    Man, this is what I don't understand with these guys comments. I posted pictures of the gauges that I'm using and described in detail everything that I've done so far, yet they come at me like I need to be some ASE certified tech with Snapon tools on my belt. I pulled a vacuum with a 4.5cfm...

    I beg your pardon - I'm not looking for an easy way out, just a guy without all the tools trying to fix his AC.

    AC Pressure Relief Valve woes

    I really get what your saying, but am I out of line saying that most weekend warriors/garage monkeys on this forum don't have those things? I mean, he might be doing it "wrong" but I pulled in a shop a couple years ago to a guy that had been working on AC for 30 years and he pulled a vacuum...

    AC Pressure Relief Valve woes

    System was cleaned and 11oz of new oil was added - all previous oil was removed. Granted...the compressor was not drained. I don't really have to measure it...each refrigerant can is 12oz so I just ad 5 and test it (2 oz shy of 62) If it isn't blowing cold, I put the last can on the kitchen...

    AC Pressure Relief Valve woes

    With an AC vacuum - it pulls down past 0 on the gauges and I let it run for about 45 minutes then let it sit for a couple hours and make sure the needle hasn't moved.

    AC Pressure Relief Valve woes

    **UPDATE** I had to do something. So, I installed a new condenser, dryer, expansion valve, orifice tube, and front manifold lines. Filled with 62oz of refrigerant and it's blowing at about 70 degrees. If I raise the RPMs to around 2k, it does come down to around 60 degrees. Low side pressure...

    AC Pressure Relief Valve woes

    I wish I could provide what you're asking, I just can't. It can't be recreated I can't cause it to happen and by the time I get my gauges on if it happens start doing it where I actually have them, all my refrigerant is going to be gone. Is there anyone that can help to determine if this is...

    AC Pressure Relief Valve woes

    Here are a couple videos I took - but the relief valve thing was not happening during this time unfortunately. https://drive.google.com/file/d/1lH0Nu9sNUQ7TVmXQi-ZDP4P0nCdIhrvJ/view?usp=sharing https://drive.google.com/file/d/1_RCyv3sPokNWAgpETOJs2skei-VjEd6A/view?usp=sharing

    AC Pressure Relief Valve woes

    So the challenge I have with this is that I haven't added any refrigerant into the system since it started blowing freon out the first time and I was driving it the other day and it just started blowing freon again, even when it's on the low side already. How does that make any sense?

    AC Pressure Relief Valve woes

    Could really use some more ideas from anyone that is familiar with AC troubleshooting. I do have a couple videos I took, but the refrigerant level was a bit low from losing freon out the pressure relief valuve. Blew cold, around 60 degrees and didn't blow any freon while sitting in the garage...

    AC Pressure Relief Valve woes

    Any ideas on this? I am just not coming up with anything anywhere I look. I could start throwing money at it and replace the condenser and refill, then replace the compressor and refill...that's over 100$ worth of freon :(

    AC Pressure Relief Valve woes

    did not use a new condenser and vacuum looked good and checked out great. If the condenser had a blockage, wouldn't it be blowing freon all the time? Usually when something like that happens doesn't the system work fine, it just doesn't get cold?

    AC Pressure Relief Valve woes

    Temp was reading 50 degrees. Can't go wrong on the math. The system calls for 62oz when empty and I only put 60 in it.

    AC Pressure Relief Valve woes

    This is a LONG story that I'm going to try and cut short. Last week I blew out all lines with air and solvent(front and rear evap, all lines to/from rear) Put in a new fan clutch (aftermarket brand) Followed that up with vacuum test - all good Filled with 60oz and 8oz of oil(assumed that there...

    2005 Navigator doors locking constantly

    It was the drivers side lock switch that must have been stuck and continuously locking the doors. I need to get a replacement. Have you guys had any luck with the aftermarket doorman units? Do they match the grey color or should I just go for one off ebay?

    2005 Navigator doors locking constantly

    Not sure if I can post about a Navigator in these forums, but I can't get any help in the "Navigator" forums so I thought I would try. I bought a 2005 navigator in great shape. Test drive revealed NO problems at all. It's in really great shape and well cared for. I drove to the store, and...

    Major AC leak after installing new components

    Around 260 on the high side. It it blowing out the pressure release on the manifold lines. confirmed that today, not the seal between the manifold and compressor. It stops blowing and runs "fine" doesn't blow real cold. the guy who looked at it today says that he thinks there is too much oil...

    Major AC leak after installing new components

    I cannot get an answer from Four Seasons on this - the pressures on the high side are high. At this point, what do I replace in order to get this back to working order? I did order a condenser, and I just replaced the compessor, dryer, and orifice tube. If I replace the condenser and orifice...

    Major AC leak after installing new components

    Wouldn't the fact that it filled fine and worked perfectly show that there is no blockage? All my pressures were good when I filled it. I cleaned the surface on the hose before I installed it and the o-ring on the compressor is brand new and held a -30 vacuum for over an hour. Feels like...
