Hi, Thanks for using JA. My name is XXX. XXX try my best to answer your questions with the information you provided. Do you have a digital multi meter? If so, Disconnect any power to your smart wheel, turn the digital meter on to OHM's and check continuity of each of the switches and functions of your smart wheel . I would also check all the contacts in the harness through your column. To assist you with this, I recommend obtaining a parts breakdown and wiring schematic for your smart wheel from your local dealer. Sounds like you might have some broken/ worn contacts within your column @ the base of your steering wheel. I hope this helps. I would need the serial number of your truck to assist you further. If you are satisfied with my answer so far, please click accept.
