Worked on a 2014 Ford E350 Super Duty XLT Flex Fuel today. In for an oil change, squeaky serp belt, wind noise at the driver's door and radio work but no display.
I did some research and found numerous posts about solder joints need solder on back of display but that is not for me and I told them.
I did the oil change and the drain plug had been overtightened and came out slow and found stretched threads and had a slight oil leak at the drain plug. I had already bought a new drain plug and it went in with no problems. Old and new drain plug pics.
The belt squeak noise was a dried out belt and slight noise at the idler. I replaced the belt, tensioner and the idler. No more noise.
The wind noise is caused by the upper hinge mount area, of the body, being cracked and pulling away and door sag. Someone at one time or another had loosened the attaching bolts at the other side of the hinge, where it attaches at the door. I tightened up the bolts and now you have to slam the door to close. When you push door by hand, up to the latch/striker, it has a springy effect that springs it back. He is aware the door will have to come off, new metal at hinge backing on the body side, reassemble and align.
