DRL and Relay Location

[DA BIG ONE]

I need to know the location of the daytime running light modual & relay.

My son reported that on my 99 Burb the low beams are out as well as the DLR's.

If you look at the Convenience Center under the left side of the instrument panel, the fuse panel, the DRL relay is the second item from the right on the bottom row. There are 3 relays there that look alike. First on the bottom right is Hazard Flasher, second is DRL, and third is Fog Light relay.

Check fuse #15, 20 amp DRL/Fog. If good there is a diode in the insrtument harrness that may have failed. To check it test for voltage at G6, a yellow wire , under the DRL relay.

The DRL Module is taped on the Instrument Panel harness under the left side of the I/P
