How can I change a bad tail light bulb on a 2019 new-style V8 crew cab? The reverse light seems an easy replacement but it looks like GM has me buying the whole housing. And now I'm reading you ought to replace BOTH at the same time. I'd go aftermarket but they are expensive. Are the stock tail/stop light bulbs LEDs? Should I check for a bad fuse somewhere? On the face of things it seems like it should be an easy fix.

I follow finally. Apparently based on my further reading on this subject my L84 model does not utilize PCVs per se, but opts instead for single-piece metal orifices resembling PCVs that redirect all gasses back up through the airbox plenum, manifold and subsequently the piston chambers bridging the two valve covers with appropriately sized rubber hoses, using a CSS ("cylinder support system") to the driver's side of the air plenum, and capping the passenger side of the plenum. This information went a very long way in explaining the mystery and offered a subsequent direction I need to go with my oil catch can connections. The direction of gasses would be better maintained with the judicious use of single direction check valves. Thanks!

I'm installing two oil catch cans, one on each side of the engine. My vehicle VIN is: 1GCUWDED8KZ130481 I noticed the passenger side breather hose was much oilier than the driver's side PCV hose. This makes me wonder where my PCV is actually located. My ride is a 2019 5.3 Liter Silverado 1500, RST, (New Style). I cannot get any two respondants to my query to agree with each other where the PCV is. Why is this so hard? Either it's on the left or it's on the right side of the engine, attached to the TB or it's not, attached to the manifold or it's not. My future as an amateur automobile repair person hangs in the balance.

The panel on my 2019 Silverado 1500 RST can be pried off and voila! Two plugs are attached to the back of it. They fit perfectly into an OE electric power outlet I bought to begin a power outlet project. Car companies put in these simple inexpensive harness pigtails to make it easier for their assemblers at the plant. Now the problem presented is what/where do these go to behind the dash? The easy answer would probably be to analyze the wire color codes for the vehicle and trace them back to somewhere.
