Thank you for the videos,I have learned a lot with them,I have a GLK 350,I put a new pressure switch,new compressor control valve and it is getting the signal to the compressor,however it still not getting cold,also it seems that if I try to charge freon it wont take it,what else can I check ?

Thanks for taking the time to describe the operation of the solenoid… I’m playing around with running this alongside a 12V compressor too in parallel and having troubling a check valve that fits these fittings. Do you know if backflow between these style of compressors would be an issue? Any ideas on getting a check valve in the loop after each compressor as far as fittings?

Great info video about the clutchless compressor. My hyundai sonata 2012 ac sometimes work great and sometimes it doesn't kick in especially after parked for few hrs in hot weather but after driving for ten fifteen min. the ac again starts working. Can you please advise what can be the cause and what should I check and how?

Hello Dr. Cool. Apreciate your videos. But a have a bit of a weird problem. Renault Clio 4 year 2014, has both a clutch and a solenoid. The clutch engages the second i press on the AC. The pressures on the gauges are ok (readings taken when the clutch is engaged), about 30-40 on low side and 150-200 on the high side at an ambient temperature of aprox 26-27 degrees Celsius. The compressor cycles normally, i think, it stays on aprox 40 seconds and disengages the clutch for aprox 8-10 seconds and so on. But the weird thing is that, suddenly, it is not blowing cold anymore in the cabin. It doesn't matter if the car is idling or not, so it's not about the speed of the compressor shaft. I turn off the AC form the button, i let it a bit to rest, then i turn it on again and it starts blowing cool air again and so on. On the Thinkdriver scanner i have also a fault code that says something like "compressor capacity control circuit, open circuit or short circuit to earth". The car has manual controls for the AC, with the exception of the recirculation blend-dor, with it is commanded by button, so it is motorized. Now, the weird thing is that this problem it is happening random, blowing warm then blowing cold. It could be that not all the moisture was evacuated from the AC circuit and when a drop of watter freezes it blocks the expansion valve or it is more lickelly that it is a problem with the solenoid valve?

@@drcoolautofix so first I was thinking do to a proper recharge of the system, with pulling vacuum the right way. Because the car is one from my job place, it is not mine, I only work with it for about 3 months now and I do not know her history of maintenance. What I do know is that it has the right amount of refrigerant because I went to a shop and they top it off but without pulling a vacuum. After that I was thinking to use the magnet trick on the solenoid valve and see if it improves the cooling. And it that test is positive then I will replace that valve.

great video this really helps explain things better. I just still am not sure on my a/c and how it works though. 2012 kia optima. I heard it is clutchless. I know for fact it is variable displacement but not sure if it is clutchless or not. I think it is clutchless....I just wish there was an exact test to do to test whether it is the compressor itself that is worn or the solenoid valve that is worn. i don't want to spend $300 and the time of replacing compressor when it is just $50 solenoid valve...

nice video. Very informative. I am having a problem with my car compressor. When i give it full throttle it some times enables the compressor? I was wondering if it was a faulty solenoid valve. I connected my car with ODB and tested. The results were all sensors were working fine. What do you suggest? will changing just the solenoid valve will help?

It's 80% likely, go ahead & graph your compressor solenoid and monitor it through live data, you should see it there, or scope it.

The solenoid is a pneumatic valve, but what is it actuating? Where is the pressure being sent to to change the angle on the swash plate? One of the pistons?
@drcoolautofix
@drcoolautofix 2 жыл бұрын
Refrigerant in the system
@parvulucian9599
@parvulucian9599 7 ай бұрын
It is the pressure of the refrigerant itself that pushes the plate at a certain angle. And that pressure increases the more refrigerant enters the compressor. And the amount of refrigerant that is allowed in is dictated by the level of opening of the solenoid.

what causes the angle to increase? just simply more refrigerant increases the swash plate angle?
@parvulucian9599
@parvulucian9599 7 ай бұрын
Yes. If the solenoid opens and lets more refrigerant to enter then that pressure will push the plate at a certain angle. The more refrigerant enters the more stroke the pistons will have.

@@drcoolautofix how do you know if you have bad compressor vs bad solenoid without guessing? I don't want to pay to evacuate system and pull vaccuum and put a solenoid on there just to find out after that the compressor is no good and the solenoid did not fix my problem. How do I test to know for sure? I also don't want to replace entire compressor if all I needed was this inexpensive solenoid.

I can replace the compressor with a friend but hate to do all the work fro the valve and then redo it for the compressor if it doesn't work. trying to safe time and work . hope you can help. thanks
