    Anybody have a 2003 387 model that can tell me where the relay and/or fuse for the power windows is located? I have relay/ fuse panels under the hood on the firewall, behind the glove box, inside the right side sleeper door and on the inside of the frame behind the cab. Not a #### one of them have a schematic or label of any kind. Window is stuck down and I really gotta figure this out. Thanks for any help you can offer.

    I have a 2004. I went out and looked at the panel under the glove compartment. There is a "door power" on the lower left side of the panel. That is all I found. If you take the little panel that has the window up/down switch off, you can try to put 12 volts to the up side of the switch.
    If that does not work, take the door panel off and put 12 volts to the motor. I have had mine apart several times. It's not difficult, but there are a bunch of screws holding it together.

    I have 03 387 but fuses is the biggest issue I have with my truck. I spend hours looking online, manuals, etc and I just can’t believe how they come up with it in that truck. Check behind the glove box panel on the top middle there is three lights that should glow green and what my issue was I have no radio, mirrors and windows just because the main acc wire connector was kind off loose.
