F750GS Heated Left Grip issue

[MagnumSix]

Hi Everyone! This is my first post on the forum. Just started riding two years ago. Started on a 2018 G310R, then last year I got a 2019 F750GS. The previous owner of the F750GS beat the hell out of it, so it had issues that the dealership took care of during their “in house” warranty period, namely fixing a head gasket leak and the cruise control. Anyway, now the left grip doesn’t heat. So I’m guessing a cable got loose or something when the cruise control was fixed since that entire left grip switch housing was replaced. Anyone have any suggestions on what I should check or how to fix it? Thanks in advance!

Maybe trace the wire or add a voltmeter to see if the cables has power to the battery.

I don't have a wiring diagram of the F750GS. But the picture of the heated grip part shows a connector for the power cable. Maybe the wire is loose right there.
