i checked the breakers
ok thank you for the answers ive checked all breakers they are working the head lights come on on high
beam but not on low beam i checked all for breakers aka fuses and still not working on 2006 gmc
sierra 1500 5.3 liter i hear a clicking noise but cant figure from where?????
The clicking most likely is the auto-headlight control relay in the engine compartment fuse box.
I agree, and I do so because TS taught me something about that on the other thread. Finally getting somewhere with this. TS, if he swaps the relays to test would that work? High beam works...
