My DRL (Daytime Running Light) will randomly come on. People tell me its not an issue but just the fact that its on my dash telling me DRL is quite irritating. Its not on 24/7, I can sometimes drive and it won't appear but it seems to be totally random when it wants to come on and tell me my Daytime Running Lights are on. Its never on when I have my headlights on which makes sense, but its still random if I'm casually driving during the day and it chooses to come on. Anyone care to help?

Check your DRL relay that is located in the fuse box. Also check the connector under the battery box for corrosion. (Not a smart place to put a connector) GM really messed up with the wiring on the 98-00 cavaliers headlights.

SOURCE: Where is the Daytime driving Lamp relay located

follow the wires to the drl relay. It must be inline from the regular light switch to the headlamps. I have a 1990 Cadillac Deville that has an aftermarket module that controls the daytime running lamps, and it is mounted on the driver's side wheel well.

Some relays are found in the fuse box under the hood.

If your daytime running lamps burnt out, take it to an electrical shop and ask them to check it out.

If you buy an aftermarket daytime running lamp kit, they can install it for you.

But, I agree, you should check for voltage and function at the relay for the daytime running lamps on your Astro.

But, if all else fails, the electrical shop should be able to diagnose and repair this problem.

Check the emergency brake pedal and make sure it is not on a bit. When the emergency brake are applied the daytime running light go out.
