2010 GL450 no controls on steering wheel
I replaced my column shifter controller as the park button didn’t activate. Everything worked fine for over a year even the clock spring. About a month ago the horn stopped working. I tried all the steering wheel controls and subsequently none of those are working either. I chard all 4 fuse locations and nothing seems to be blown. Is there a steering wheel module that may be blown causing all buttons and horn to be deactivated. I checked all connections in the steering column and horn/airbag assembly.

3 Torx bolts holding the plate along with a ground. Control module is the black box with all the connectors coming out of it. if youre buttons and horn arnt working my money is on the module
