    Hey Guys! I just wanted to add that you can also do a resistance measurement using an ohm meter to test the control valve. I did not film this procedure because I was not sure of a specification. After comparing the old valve with the new one, I found that they both measure to about 10 ohms. That seems to be normal. The resistance measurement test can tell you if the valve is faulty electronically but not mechanically. The valve plunger could still be sticking even though the magnet is working fine.

      I heard through my research that you can put a balloon over part of the end of the valve and blow it up and if it deflates with power given to the valve then it is bad and if it doesn't deflate then it is good....basically testing to make sure when power is given to it, it opens correctly and is not stuck where it doesn't fully open....you could also breathe through it using something that fits around it

      Hi, exellent video. Thanks for posting.
      By the way there is a tool to test the duty cycle of the compressor.
      It is expensive but you don't have to guess what the problem is. It even allows you to test the resistance on the valve, no need to get the multimeter out.

    I love you man and you are a master mechanic and I am a shadetree mechanic with a degree in Chem Eng. The static pressure of the refrigerant doesn't tell much. Much of the refrigerant is liquid and the pressure is determined only by the ambient temperature when the car is shut off and cold. The pressure will stay the same until all of the liquid has evaporated and then if more is lost, the pressure will stop dropping.
    For example, if you had a gauge on a can of refrigerant, the pressure will remain the same until all of the liquid has evaporated and then it will stop dropping. Great diagnosis by the way!

    • @ADVANCEDLEVELAUTO
      @ADVANCEDLEVELAUTO  3 роки тому +8

      Great info! For my purposes, I look at the static pressure because that’s what the cars computer is looking at to determine whether or not it should turn the compressor on. If the A/C pressure sensor is reading low pressure then the compressor will not activate. Thanks for watching!

  • @josephwash109
    @josephwash109 3 роки тому +9

    Here's my theory: The original root cause of the poor A/C performance was the sticking temperature door, which you solved. However, previously another mechanic simply shot the parts cannon and replaced the compressor with that aftermarket unit. The aftermarket compressor is a cheap knock-off, so it failed early. That brought the customer to you. Chrysler has used Denso compressors for a while (the same manufacturer associated with Toyota), so likely the parts changer mechanic caused the customer additional grief with inferior parts by not doing a thorough diagnosis. Lots of compressors get changed for no good reason, aside from the fact that the mechanic does a bad diagnosis. That's likely why the cost is so high. The replacement valve would likely have worked in an OE compressor. I'm sure your friend appreciates that you were able to fix the problem. Keep up the good work!

    I always like to come up with a hypothesis at the beginning of your videos based off the customer complaint, definitely off on this one.

      Yes I know why you thought that way which is good initial thinking. That's why a few more tests to rule it out is so worth it. Pressure of the system definitely would rule that out and point you right towards the problem being compressor related...

  • @jovangrbic97
    @jovangrbic97 3 роки тому +4

    It doesn't look like the control valve solenoid does *anything to move/angle the swash plate* . It only seems to be a valve, so I'm thinking it is just actuating a refrigerant bypass within the compressor, basically when commanded off, it allows full bypassing of the refrigerant going directly from the outlet back to the inlet. When fully ON, it blocks any refrigerant bypass and allows it to flow through the whole refrigeration loop. The solenoid probably could have been fixed by cleaning and lubrication, as there is nothing to really break, except for the valves the fairly weak magnet actuates to get stuck. You could have tried that before full replacement. Also, since the blend door was broken the whole time to a degree, that means the evaporator wasn't getting proper airflow, making it run cold, restricting gas flow to the compressor inlet, and causing the symptoms you saw... I bet with the blend door fixed and the original control solenoid valve cleaned, the old parts would have worked!

    • @ADVANCEDLEVELAUTO
      @ADVANCEDLEVELAUTO  3 роки тому +2

      Interesting theory but the blend door got stuck during the time we where waiting for the part. During that week we had a random cold front come out of nowhere and he turned his heater on for the first time this year. The next day he tried to turn it back to cold, but it wouldn’t cool anymore like it did before. Plus, after replacing the compressor, I saw an immediate change in the pressures. The pressures read good even though the cabin was being filled with hot air. That’s when I knew the blend door had gotten stuck. I’ve seen this happen before on Jeeps. These were two separate problems.

    • @jovangrbic97
      @jovangrbic97 3 роки тому +1

      @@ADVANCEDLEVELAUTO I can agree on the blend door being a new issue. But don't you agree that the control valve is just a solenoid opening or closing a valve. As long as the coil is not shorted or open circuit, it is electrically in order. That just leaves the valves themselves to be INOP, and apart from damage to the sealing surfaces, it seems most logical to me that the valve was sticky, and thus limiting the function of the compressor by bypassing most of the refrigerant.

    • @ADVANCEDLEVELAUTO
      @ADVANCEDLEVELAUTO  3 роки тому +3

    GM has used the variable displacement compressors since the 80s but they still had magnetic clutches to engage the compressor. It just didn't cycle with low load the valve would shift and unload. So the magnetic clutch has been omitted altogether? Does the compressor always turn and does it have the capability of unloading completely with no call for compressor operation i.e. HVAC turned off? Interested to know. Been out of the auto field for awhile now but still do HVAC and refrigeration daily.

    mid 30's-40 is normally a good working system which everyone is happy with and comfortable! but there's most likely other a/c components that would have to be replaced to reach that goal which obviously is an additional $$$ and the vehicle's got so many issues it just ain't worth it to fix it all to where it should be like new you would go and buy new!lol.
