Hi,
This is my first post here. I searched the forum and didn't come up with anything.
Here's the problem. Suddenly the daytime running lights on my 96 Lumina stopped working. Normally they would come on any time the key was in the on position. All the other lights operate correctly, headlights etc. are fine.
I know that they don't come on when the parking brake is set, so I tried setting the parking brake and then releasing it, thinking that maybe there was a problem there, but it didn't help.
I looked in the owner's manual to locate the associated fuse but couldn't even find that.
Any ideas? Thanks.
By the way, car was mfg. in Canada.

Welcome Aboard!
The DRL operates through a fuse in the underhood electrical center. Look in the black box along the let inner fender (driver's side). You'll likely have to remove the upper angle brace to get access to it. There should be a fuse, a DRL relay, and possibly a diode in the UEC for the DRLs. The lamps receive power through the fuse and relay, and the diode is primarily for the dash-mounted indicator lamp for the DRLs. Make sure the fuse is intact, and the relay is operating. If both are working, the last item in the circuit is the DRL module (inside the vehicle). On later models, the operation was controlled by a Body Control Module, but I believe your '96 still has the separate DRL module.
If all the rest of the lighting operates normally, and the fuse and relay are intact, you may have to access and diagnose signals at the module itself.

Thanks. I did find the 15 amp blade fuse on the right of the dashboard that is related to the DRL and that is OK. I'll check into your suggestions. I don't recall that there has ever been a dash indicator lamp, or at least it has never worked in the 7 years I've owned the car.

I had another thought. I know the DLR's are off when the parking brake is on and come on when it is released. Could there be a switch that is not working to tell the DLR when the brake is off? I don't use the parking brake often, but my son recently drove the car and he does tend to use it.

BTW, thanks Bowtie. It was the diode.
