electrical problem

Hi i have a 99 F350 PSD. my door locks and power windows do not work anymore.... the doors try (seems really stiff) and some unlock/lock from the passenger side but nothing from the drivers side. the mirrors dont work aside from the passenger side going down but thats it. any clue where to start? thanks!

The door locks you can fix for free if you've got the time. Look here... Power Door Locks FIXED!!!! - Ford Truck Enthusiasts Forums I did this to mine about two years ago and they have worked perfect ever since. Or you can replace the actuators for about $45 each.

If the windows don't work at all...any of them...then you've probably got a fuse or a relay gone bad on you. If they work but super slowly then you may just need to lubricate the channels that the windows go up and down. Some guys just spray something down in there. Others actually apply a small amount of something to help them slide easier.

I guess i wasnt too clear. sorry... the windows work just fine. The slowness i was referring to was the actual door lock stems. they just seem stiff or hard to move up and down (therefore i was wondering if that is typical or if that could be part of the difficulty for the motor trying to work them up and down). They also seem to go too low once they are down. anyway ill take a look at the "free fix" and see what i can do. thank you !!!
