06 Trailblazer SS, Low beam and day runners just went out. High beams still work. Any ideas on why his lows will not work??
Thanks for any ideas or help.
DRL (daytime running lights) and lowbeams are the same bulb...could be as simple as the bulb...

9006- lowbeam/DRL bulb
9005- high beam


otherwise check yur fuses
:tiphat

thank you. Will double check, but lights have been checked and so have the fuses..:x could it be a short? Are there fuses anywhere else for the headlights??
Again thank you for the help.
yu live anywhere near belleville/nutley nj? i saw a white and black SS within this past 4 days driving with their highbeams on for no reason :undecided :crazy:

another issue is a common (VERY) common headlight switch problem...2006 still under warranty?

There is one fuse for each headlight and one relay (#46) that covers both headlights. Try switching #45 and #46 to see if the lights work. If they work, get a new relay. Is only one light out? It could also be a burned/melted socket.:m2:

Probably not the headlight bulbs...

This just happened to my '06 Envoy - The headlight 'relay' - a solid state relay - just quit one night. I swapped the relay with the one for the engine cooling fan and made it home. The relay eventually failed hard, and I replaced it this week for about $42.

Is a 20 amp fuse what was originally called for? If the dealer told me to use a fuse bigger than called for, I would get it in writing.:m2:
