I just did what you said and the solenoid valve seems to be working fine
I put 12v to it and the solenoid is operating fine, when it opens, air flows thru, when power is removed, no leaks (i blew into both sides and it seals off)
Just something to add, the car has about 35k on it. Not to say that components can't fail at low mileage, but it isn't really high mileage thou either..
Any other ideas? I'm not familiar enough with this car to figure it out without help.
Thanks in advance.
