2008 Chevy 2500 HD Duramax low beams will not turn on.

If you call 505-424-3899 we can schedule you an appointment.The estimate for the diagnosis is $127.00. We will fallow this diagnostic approach. 1. With a scan tool, go into Body Control Module (BCM) data and monitor the headlamp switch and low beam relay command to confirm both show inactive. 2. If commands are inactive, access the BCM X5 connector, remove or cut pin 23 Pink/White wire and see if the lights go out or stay on. 3. If they are still on, check the Pink/White wire for being shorted to ground back to the underhood fuse block. 4. If the lights go out with the wire cut, replace the BCM.
