Good afternoon, I am new to the forum so forgive me if I am not posting in the proper area. I have a 2018 Traverse, I recently had the dealership install a hitch, I then went in and installed the ride control switch with the tow option that I ordered from GMPartsDirect.com. Now when attempting to use the selector to select the tow option, the tow option is bypassed and the ride selector goes back to x2 for the normal drive mode. Does anyone have have any other experience with this? does that dealer have to reprogram something? Thanks in advance for any support.
