Looking for OEM lower grille light bar switch

Like many before me, I’m in need of the GM light bar switch. GM part number 88963885

Fully understand how difficult these are to come by today but hoping for a miracle here.

Yeah I looked at that site over the weekend. Not sure how it works because I tried to add it to my cart but it kept removing it automatically and displaying the contact info for GM Parts Headquarters in Portland, OR. Tried emailing them and it got kicked back. Went to their website and no search results for Hummer.

The hole diameter is 15mm. Ebay has 16mm lighted that may screw in or open the hole a bit:
16mm 12V LED ON OFF Push Button Power Switch Latching with Wire Socket Harness
or you can get one in the 7023281 kit:

The 88963885 is part of the 7023281 kit included with the 19132765 & 19159112

Both switches have been discontinued for many years.

Amazon has a two pole switch that fits. Two for $5.99. You can buy the matching mini spade connector at the local parts store.
