Just to clarify one more thing because I forgot to mention it. When the light/lights go out it is not always while driving or flicker over bumps. It has happened while parked in my driveway. Also giving a few knocks to the light will not cause it to go back on. I had another chevy do that and I located the source as the plug on the harness

I don't feel like reviewing; did you VOM all the connections?
The bulbs have different grounds so that is ruled out.
The DRL is on it's own fuse and relay.
The high beams are on their own relay and fuses.
The low beams are on their own relay and fuses.
The relays are triggered by a signal from the BCM.
The fuses are after the relays.
Seems the only thing left is the pigtails. I would suspect the earlier splice job.

Shouldn't the fuses be before the relays to protect the circuit ?
Sorry don't have a wiring diagram.

The wiring diagram is in this thread. On page #1.

I checked the continuity of all the wires related to the front lights on both sides and everything seems fine with all that. This car does not have a spliced in pigtails and I checked for charing and corrosion. The fuses are new and tight and the relays are in good shape and secure. The grounds are cleaned and secure.
I will run through the wiring again and even though the bulbs are almost new I will replace them again to verify that the new ones weren't defective.
I want to rule out as much as possible because unlike the other issues this one has me stumped and either going to get me a ticket or an accident.

My memory must be bad, I thought you said you had replaced the sockets.

Yes sir I did but they were on other vehicles. One trailblazer and one impala

As I tried to point out there are 3 independent systems failing at the same time. That kind of limits the problem point to the one common thing; the sockets.
Loose pins are what causes the corrosion and burning in the sockets. Easily checked.

I can check them again. Both times I checked them there was no looseness of the wires/pins, no charing or melting of the harness or wires and I even looked in where the wires seat in the plastic clip and nothing. That was the first thing I checked given I had them burn upon 2 other chevys I've owned in the past. I'm at point that I don't know what else to do. Most of this stuff I have checked before I posted this except for the grounds and checking continuity and that's why I asked is because I was out of ideas and beating my head on the wall.

Maybe somebody put the wrong bulbs in? H11 looks pretty much the same as H13, I don't know if there is any difference other than one has an angled socket but maybe the pins are different.
