    Hey guys, I believe I have a problem with the truckside wiring. The plow light on the driver side doesn't work. Its not a dead bulb because that has been replaced. The turn signal on the same side is fully functional. What should I be checking. This is a three plug MMII

    start with power at the bulb. also check the pins in the plow lighting harness at the iso to start

    Did you just install the wiring? On the GM's the connectors for the vehicle light harness & the headlamp harness are reversible to account for positive & negative common.
