I just bought a 97 Ford F150 XLT. I noticed while in gear the drivers side power window wont roll up or down. When I put it in park the window works just fine.
It may be a loose/bad wire that is shaken out of place once in gear due to the vibration. I recommend turning on the your F150 without starting the engine and try rolling down/up your window while opening and closing the door to determine if it's a bad wire as wires in the joint of a door tend to fail first in older cars. Either way, it sounds like an electrical issue.
I just turned on the power on the truck and the windows work. I shifted the gear into drive and neutral and the windows work even when closing the door. As soon as I start the engine and put the truck in drive, the windows don't work. I put the truck in park and the windows work. Never seen anything like it. Thanks for your help.
