One of my DRLs was out. Checked a number of sources, all suggested different lamps. It looked like a 3157 to me, so I made sure I had one on hand and raised the hood.
Before I started, I had checked the steps required to remove the headlight assembly; more than the old Envoy, but it was a nice afternoon for a small driveway job.
Three bolts (10mm) hold the assembly in place, you could see 2 with the hood open. The 3rd was at the bottom of the assembly. To reach this, the front fender-liner had it come out (I only removed the outside bolts (7mm) and plastic push-pins). A few minutes later, the third bolt is out and the headlight assembly is loose. But would it come out, nope, I could not get the wider backside of the assembly through the hole.
Decided to remove the grill; but, upon inspection, it and the complete bumper are one piece. I removed the 6 bolts (10mm) holding the top of the grill in place. With these bolts out of the way, I could pull the front of the grill out enough to get my hand behind it. With the headlight assembly pulled forward I could just touch the DRL socket with my fingers and turn it to loosen and remove.
It was a 3157. 10 minutes later, it was back together, about 90 min from start to finish.
