You said you bought it CPO? Take it to the dealer.
My thoughts, it kills the license plate lights.
Grandpa was running from cops? Or avoiding Red Light Cams? Thanks for the smile... ;-)
You will have to ask the CPO dealer as obviously since you asked the question it does nothing when pushed. I will say that I had aftermarket heated seats placed in a Tahoe a few years back and that rocker is a dead ringer for the one they used...but you also said you had OEM seat heaters.......
If it really was an older couple's car maybe the switch controlled the in-car O2 for his breathing tube.......fun to guess anyway.....
