Help, my high beams will turn on but low beams and daytime running lights will not. I have a 04 Trailblazer and all fuses are good!!:thx

Your DRLs and low beams will not turn off? Very likely you have a bad relay 46 under the hood. Swap it for a short while with its twin, the fan relay #45.

You need to edit your post to say whether "of" means "on" or "off".

Either way, it's probably a bad relay #46.

Still most likely a bad relay 46, or both fuses 3 and 6 are blown. There's a fuse for each side low beam lamp. Much less likely is a problem with the wiring. You haven't changed to brighter aftermarket lamps, have you?

Ok ''why did you say this''. I had a problem with my drl not working and 1 low beam was out. the only one's they had in the store was 1 brighter... low beam worked after that but drl didn't work. But started 2 days later . but why did you say this about brighter bulbs? Is it because they will burn wires,its still the same bulb number.9006

If you put a higher wattage bulb in that what is recommended, you can do damage to the wiring

:iagree:

Anything over 55W will damage your factory wire harness at some point or another
