Do your headlights work? High beams more specifically? If that answer is yes, then the bulbs are fine. DRLs are nothing more than a lower voltage being sent to the high beams in the Sunfires. (They use 9007 HB5 bulbs, which is a dual filament. highs and lows in one bulb). IF the LOW beams work, but not the high, try new bulb. Otherwise its off to try and find that relay... which is a pain in the ass. Personally, I pulled my relay out and never put it back in (I have HIDs in the car now).
On my 98 sunfire, the tail lights and marker lights only work if you turn on the headlights. If only the daytime lights are on, the Pontiac on the trunk is illuminated but no other lights at the rear until brakes or turn signals are activated. This is common with a lot of vehicles out there. Daytime running lights are not necessarily the same candle power as the headlights. I can tell a big difference in mine.
no
Our daytime running lights just stopped working on our 2007 Toyota rav4 bulbs???
Check the bulbs, check the fuse then check the switch.
Had the same problem. Found it to be a bad ground wire for the headlights. There are two ground wires for the headlights, both are directly below the battery. You can see one of them if you remove the drivers side headlight. It is right behind the radiator hose. The other is a few inches from that one.
light sensitive sells
check your fues
Taillights and daytime running lights not working may be caused by a blown fuse. The fuse can be found in the fuse box in the engine compartment.
What, exactly, are you trying to do? Does the car already have AC? Is the AC not working? We need a little more info.
Bulbs burned out or fuse and or relay popped
the daytime running lites go out when you put the trans in park. they also go out when you depress the parking brake. i would start looking there.
I had a similar problem where just one of the daytime running lights didn't work, this was also accompanied by one of the high beams not working. The wiring for that circuit is exposed too much and is subject to corrosion. Test the wiring at different points until you find the short, or see the corroded wires. Once you find the problem , its an easy cut-and-repair job. Hope that helps.
