Question on fuses and wiring

    My plow (8' RD MM2 on a '03 Chevy 2500HD) has this bug in the wiring that only pops up when the plow is disconnected. When I turn off my truck the dashboard lights stay on even after the interior lights have shut off. I've tried dimming and turning the dashboard lights off completely but the gear panel and odometer stay illuminated. The only solution I have found is to re-seat the fuses in the plow fuse relay under the hood. I pop out the two red 10v fuses and then put them right back in, close the hood, open and shut a door on the truck and the dashboard lights goes off. I have to do this every time I park my truck for the night or the battery could run down. With the off season coming I was wondering if I could take out the two fuses to save myself all that trouble atleast for the summer. If anybody has an explanation for this or a better way around it I am all ears:confused:

    Try disconnecting the RED wire on control harness, It should be connected to
    a switched {ing on} power source.
    If this does not help, you may have a problem in your E-Force box.

    Your dealer can check the isolation module, off the truck, to see if that's the problem

    Thanks for all the helpful responses!:waving:

    I keep meaning to bring the truck in to my plow dealer but they're way down the coast. I called them up once and they talked me through checking all the fuse relays and wiring harnesses but nothing was out of the ordinary.

    Will poppping out the fuses be okay in the meantime, until I can get it seen by the dealer?
