Title: Low beams not working
Post by: 260z on November 01, 2006, 10:13:00 pm

79 gmc sierra,350, 4 barrel. The high beams work fine but  nothing from either of the low beams. Checked the dimmer switch. seems to be ok. Is there a fuse or a relay I don't know about or do I have to start following wirers. Thanks, any idea's welcome.

Did you unplug dimmer switch and jump the wires across. I have had them look and act fine but still be bad.
