recently noticed some strange noise coming from the truck after it had been turned off.... I mean like hours after it has been turned off.
The first time I noticed it was when I was sleeping in the back of the truck a few weeks ago. I was worken up by a humming noise that had started. no idea what it was got up out of the truck, started it up, noise went away, shut downt he truck noise went away, I went back to bed..
Second time I noticed it was when I was walking out to grab somethign from the truck several hours after it had been shut off, again it was at night.
Sounded almost like a small pump humming away, seemed loudest about mid way down the body of the truck
