    A 2003 GMC 2500 HD with 2009 Western 8' Ultra Mount(straight) has no power to remote and lights won't switch over to plow.Plow was installed by dealer and worked fine for 6 years.When plow is unhooked lights on truck won't come on on auto setting have to turn headlight switch on.Before plow stopped working remote was blinking.Truck was parked for 2-3 months with blade attached and because blower would cut in on truck( on its own) battery would be completely drained.As a result I had to boost truck a couple of times to move it plow at those times worked.All fuses are good and plugs on truck and plow are not corroded and no bent pins.I'm leaning toward it being the isolation modual because even with plow off headlights still won't come on .
