Vacuum pump not working

Where is the best place to get one of them, junkyard?

Its for a friends truck, it is stuck in defrost, so I think that means the vac pump isn't working . To tell you the truth, I haven't had a chance yet to diagnose this problem

I took mine into the shop. Pretty sure they ordered the part from FORD. I would check Rockauto.com and see if they have it. My problems were the same and thats what they had diagnosed. Replaced the vacuum pump and it solved the problem. Hopefully this helps a little.

turn the key on while someone stands next to the pump, then you'll know for sure if its working or not.

Drove our truck on a 200 mile trip through the mountains this weekend and everything worked PERFECTLY except for the last 10 miles when we noticed that the cabin was warming up and the A/C was on but not coming from the upper vents. It was coming from the defrost vents and maybe the floor vents. I got home and checked for vacuum leaks(there were none), and checked the operation of the vacuum pump and found that it was not turning on, so I disconnected the electrical connection to the pump which showed 12+ volts on the multimeter, plugged it back in and it worked again. I cleaned the connection with electrical contact cleaner and reconnected it and everything seems fine again.. weird.

I know it doesn't work, and I do have 12 volts at the connector. I will take a look at Rockauto. I always forget about that site

The vacuum pump is easy to disassemble, and contains a piston pump, motor, electrical plug, check valves, and a small pressure switch. This switch has one moving part which is a small white plunger that is normally protruded and retracts when the vacuum pressure reaches a set level which lets a small bendable metal tab move away from its electrical source similar to a electric relay. On the plunger there is tiny thumb-screw that you turn in or out to vary the amount of pressure exerted on that bendable metal tab. Mine was stuck in the "open" position and all I had to do was turn that screw "in" a quarter to a half of a turn and the pressure switch again started working like it should. Vacuum pump is switching on and off like it should again and my vents/defroster are modulating like normal. It was a super easy fix and I hope this helps someone avoid buying a new pump.
