My low beams won't work for anything. I'm currently running high beams. I went to the strap yard to get bulbs and relays to replace the ones i have now. They are still not coming on i replaced the fuse box and everything containing the low beam headlights. Can someone help me?

Hi,

Each low-beam bulb has its own fuse. Make sure they are good. Both are located in the under-hood fuse box.

If you find the fuses are good, I suspect the HDM module/relay is bad.

If you look below, I attached two pics. One is the headlamp wiring schematic and the other shows the fuse locations and relay.

Check these and let me know what you find.

I just found a recall related to this issue. If this has never been repaired by GM, they may still cover it. I attached the recall information below. (Pics 3 and 4)

Take care,

Joe
