Thank you for taking the time to make this video - very helpful in understanding how to test the a/c valve. One minor point, the valve is a voltage-controlled pulse width modulated actuator. The control voltage would vary between 0.4 and 0.8 volts DC, not amps. Thanks again.
I have two solenoids one from an old compressor I changed out and I can blow through it and it closes off when I put power to it The current compressor I'm working on I can't blow through it at all do you know what that means
My compressor clutch spins. Gas at 115psi. But low and high wont differ. I can only think control valve is shut. So if shut is 12v and open is 0v? Problem started after replacing bat. Maybe climate control settings in cpu need resetting. Ill play with voltage on valve. See if i can over ride valve control.
short , immediately to the point
that's what TH-cam should be
thank you
I agree

0~12 Volts 0.4~0.8Ampere
Thank you very nice
tnx for video
Thank you very much.

Thanks, that was very helpful!

So if I back probé it with a power probe and provide battery voltaje while connected will it activate?
good👍

Where did i get this testing tool

i want to ask..if i want just to replace valve sensor..need to remove gas aircond or not?
Yes
Testing tools price
PWM signal , not current
Why doesn't the Mercedes compressor work even though the compressor sensor is good?
I did this with my compressor and a ballon.
