Removal of the passenger side A pillar trim is easy. Use a trim removal tool to pop the top spring clip of the trim piece at the headliner. Be aware there is a small bungee cord bolted to the A pillar trim and to A pillar. Presumably this bungee keeps the trim panel from flying off when there is an airbag deployment. Unbolt both ends and remove the cord. Then remove the two torx screws that attach the speaker to the trim panel.
You can then lift the trim panel upward and out. No dash disassembly is required.
My 2021 Yukon Denali has the Pearl Beige Metallic paint with the Teak/light shale interior. The identification on the existing A pillar trim panel says it’s color is whisper beige. Since GM only offered these interior colors on the Denali, I had to live with whatever color A pillar trim panel with assist handle I could find.
I ended up finding a Dark Atmosphere trim with assist handle and the associated caps (2) to cover the fasteners at GMPartsdirect.com. I purchased these last spring so I don’t if they are still available. However, the part number for the assist handle is 84691899 and the cap part number is 84545065.
Now, before I started, I made the assumption that GM provided the mounting provisions on the A pillar for the two mounting bolts that attach the assist handle to the structure. I figured that all Yukon body frames started out the same to save costs.
I was partially correct. The mounting holes and reinforcement was there, but the holes did not have threads for bolts. Not a big issue.
I measured the hole size and determined it to be approximately .218” in diameter. From this I decided this would be close enough for either a 1/4-28 tap or a 6mm fine tap. Since I already had a 1/4-28 tap, I proceeded to tap both holes for 1/4-28 x 1-1/2” long bolts.
I looked at trying to modify the new assist handle trim piece to accommodate the existing speaker, but decided I neither had the skills or the tooling necessary to do a job that looked professional. The speaker mounting is thermoformed into the trim piece. Anything I would have tried would have looked like a butcher job. I ended up Ty wrapping the speaker to the plastic tube running down the A pillar.
I took the original A pillar trim panel to Lowes and found a spray paint that was remarkably close to the original color. It took several coats of paint to fully cover the original Dark Atmosphere color but it turned out as well as I expected.
Installing the new assist handle went ok once I got all the tabs lined up. Bolting it down went well too
