    2011 Silverado. MM2 low beams not working but highs do. Any thought to trouble shoot?

    Is it a new install? Check the orientation of the common wires in the plugs where the plug-in harness plugs into the truck's harness.

    I swapped it from my 08 silverado to my 2011. When you say orientation do you want me to be sure the plug isn't connected backwards? Do you know what pin on the plug should have voltage for low beams?
    Thanks!

    CI is talking the A/B plugs on light harness. They can be hooked up on either side. Need to check that you have the common on the correct side.

    At each plug for both the high and low beams, the wire in the socket, on the plug-in harness, labeled "COM" should orient with the black wire on the male plug from the truck harness.

    I have confirmed the black wire does connect to the common wire.

    I found the issue. The common wire on the drivers side high beam was backwards. All good! Thanks for the recommendations.
