Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is***** hi beams or flash to pass option work? Thanks.
Sorry about delay. Check the operation of the headlamp grounding relay in the body relay block. Wiggle the relay and check for it to click, indicating a poor connection. Remove the headlamp grounding relay and check for loose or overheated terminals. The body relay block is under the drives side of the dash near the fuse block. At the connector for the multifunction switch, try grounding the Yellow wire at pin E13 with the headlight switch on and see if the lights work in high and low beam then. If the lights do work, check the Yellow wire from the switch to the grounding relay located in the Bussed Body Electrical center behind the left side of the dash for an open circuit. If the wire is OK then swap the relay with another one. Check the Black wire at the relay to see if it shows to be a chassis ground. Check for any burned terminals at the back of the electrical center. Let me know how it goes or if you run into more questions, thanks.
