Diego2014Edge Posted April 28 Report Share Posted April 28 Any ideas as to what else to check? 1 head light is not working Changed bulb, ballast, fuses, switch, still not working. Checked the main ground, its fine What could cause 1 light to fail that I have not already checked? Anyone come across this issue? Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted 21 hours ago Report Share Posted 21 hours ago Ever get this fixed? One other thing that can cause thus is a tripped or locked Field Effect Transistor circuit inside the Body Control Module. One way to test this is turn the headlight switch on, disconnect the main wire plug from the back of the broken headlight assembly and check to see if there's power to the lighs power pin. (On the passenger side, the power wire is blue with green stripe.) If there's no voltage to the power pin the BCM has locked out the headlight. An easy fix for this is to use FORScan. Go to the service/configuration tab in FORScan and select BCM Module Reset (or possibly Front Light Control Module reset). Then clear the DTC error codes and this should reset the BCM.
