Everything started working again for no reason. On a trip over to Valdosta, it happened during driving. Once I got home, I went out to check out what is going on.
I turned the key on (did not start to hear). The pump was running and running. I looked over the hoses and realized that only one line went outbound (there are 4 lines total, but they all connect together). I wiggles the hoses around a little right a the pump to see if there were any that was loose. About 30 seconds of messing with them, the pump shut off. I went into the cab and the vents had air blowing out of them again.
So, I either have a leak right at the pump that I fixed by wiggling the hoses arouns (but everything is tight and I could not really move anything), or the pump is just not pulling a vacuum correctly and me moving it around caused the internals to be jarred around to start drawing vacuum.
Do these pumps act up like this?
Looking for ideas. I can't fix it when it is working.
