I have a 2004 chevy monte carlo ss intimidator and have a problem with the low beams. After reading all the forums i replaced the relays even the one behnd the driver side fuse box (really hard to access by the way) and nothing. Next i replaced the bulbs just cause and even the headlamp switch and still nothing. Checked all the grounds and there good. The high beam only works when i pull torwards me. So is it the bcm or signal switch? Help anybody!!!

 

I have a 2004 Dale Enhardt edition, my day time driving lites quit working and no low beams, replaced the multi function switch, turn sig switch, no fix , replaced body control module, no fix, got into checking dark blue wire wich is the ground wire at the multi function switch,( turn sig switch), found high resistence at this point, in checking problem, i found that the wire loom that runs between the battery and the right front inner wheel house had been eaten with battery acid and corrosion. reparied bad wires with soldered in jumpers and schrink tubing and all is well with my low beams , high beams and day time running lights. If you are handy with fixing this problem, you can save a lot of money , because this front wire harness for head lites horn,fog lites, turn lites ect, cost list price from a chev dealer is $989.00, hope this helps. I am a retired mechanic, and this problem was driving me nuts too.

 

Thanks ever so much for posting the fix for this persons wireing issue!
