    Ok folks, I'm now on my 3rd Iso module for the same issue, the passenger headlight on the truck will not turn on. each year, I wind up buying a new module late in the summer when the headlight stops working. I've tested all the wiring and know it's the module (side by side testing with new modules and old one) I've had minimal luck with cycling the module from plow to truck.

    Has anyone else had this issue and/or contacted Western ? I opened a case with the local dealer since I know it has to be a defect but I wanted to share and inquire here as well.
