I have an 2000 F250 4x4 Extended cab. I have encountered several issues; The passenger power window fully operates up/down from the driver side but is interminted from the passenger side. The passenger side power door lock does not work except manually. When traveling on the highway and I hit 60mph the AC cuts off from the foward vents and begins to blow from the front defrost and then switches back. Does any have a clue of why this stuff may happen?

Thanks

The climate control will default to defrost when vacuum is lost. (blend valve) I suspect at higher speeds and more throttle the vacuum is lost. see if lifting off the throttle restores a/c to the dash vents. Check for vacuum loss if this is the case.

I have a 2000 Ford F-250 7.3L 4x4 Crew Cab...experiencing similar to Ed...something is shorting out the window/passenger. The guy worked on it (I have to take it back), but he said it was burning up...he fixed it for now to where I could get the passenger window down from the driver's side, but not up, and up and down on the passenger side. The compass display up top is not lit. Now, I was driving today...stopped at a light and the truck cut off. Started right back up...then down the road cut off at 70 mph. Pulled off road...tried to start it it was cranking, but not turning over. Waited a few more minutes and it started right up and never happened again over the next 100 miles. I have tried to look stuff up...seems to me that it might be something related to the fuel, or some of my research said something about the Map Sensor (this cord/plug). Any suggestions? No lights are on so I can't get a diagnostic from AutoZone or somewhere similar. Any suggestions?
