Chevy Cavalier DRL lights not working

When I put my Cavalier into drive gear, the dash indicator for my DRL flashes a few times then and then daytime running Lights go out. My service vehicle light is also on the dashboard. It is not the service engine light, the one with the wrench symbol on it. The low and high beams work fine when it turn them on manualy.

I have tried changing the bulbs with one from the dealer, but that is not the problem. Is there a wiring problem or relay or something that went bad. Thank you.

There is a DRL relay that is attached to the forward lamp harness, right about in the middle of the front bumper. That could possibly be a failed part, but a really common problem with headlight issues on the Cavalier's is the actually wiring harness. There are a bunch of splice packs along the forward lamp harness, and what happens is that they get moisture in them over the years and start to corrode. Usually once you finally notice a headlamp or DRL issue, it's far too late and you have multiple spots in the harness that are bad. I can't tell you how many of these I've had to replace over the years due to this issue.

So, you might want to start by replacing the DRL relay since it's cheap and easy to do. If that doesn't help your problem you will more than likely be replacing the entire forward lamp harness. It's usually not worth the time or effort to try and fix all the bad spots in the wires.
