I have a quick question the vacuum pump for ESOF and the climate control that is on the passenger side of the vehicle. There is a black line going to reservoir. If you plug that line the pump should build up vacuum and shut off right? Mine runs constently after being plugged and I only have defrosters. Just making sure I am right before I order the new one from partsgeek as it is a ton cheaper than ordering from ford or autozone. And also the PVH solenoid how should I test that with a vacuum pump to see if that is also bad. I can hold vacuum at the bottem port but not on the top port? Is that bad also, I plan on just plugging the lines and using hubs as manual for right now because I don't have money to replace hubs as they have a slow vacuum leak when I tested. Thanks for any insight and help.
