Why all of a sudden the low beams dont work but everything else does.
Replace the bulb. The low beams and high beams use separate parts inside the bulb. If replacing the bulb does not fix the problem, check the fuses.
If the low beam headlights on your 2006 Chevy Equinox aren't working while the high beams do, it could be due to a blown fuse, a faulty headlight relay, or burned-out low beam bulbs. Another possibility is a wiring issue or bad connection in the headlight circuit. Checking the fuses and replacing any burned-out bulbs would be a good first step in troubleshooting the issue. If those are fine, further inspection of the wiring and relay may be necessary.
check your fues
the low beams should not be on a fuse it will either be the dimmer switch or the headlight its self. for your problem i would check the dimmer switch first J.
Check the low beam bulbs to insure that they have not burned out. Check for a low beam fuse, then check to see if the dimmer switch is bad.
I would look for a bad ground if the fuse is good
Your low beams are burnt out. that happens alot
you may have a bad relay. If both of them are out, that is probably the relay for the high beams or it could also be a fuse.
Bad dimmer switch.
I'm not sure if it is the same on a 98 as an 04. But on an 04 there is a relay box under the hood that has a relay for high beams and a relay for low beams. On an 04, it is on the driver's side behind the battery. You can check the relay by popping it out and exchanging it with another one that is working. Hope this helps
low beams my have burned out
Your high beams work but your low beams do not because the switch is broken that switches between high and low beams. Electrical switches wear out.
