Hello and thank you for using Just Answer. My name is ***** ***** I'd like to try and help. I am sorry that you are having issues with your Mack. I know this can be frustrating. On your issue, There are a few different things that I would check. This being a 2014, it does not have an lcm so the wiring is still the basic system with mack. I would check the connections at the cab firewall and make sure there are no corrosion present. Check the EPDM which is the fuse block on the lower drivers side and make sure the wiring outside and connections are all clean and no rubbing has occurred. I would check the wiring near the base of the steering column as well and make sure there are no defects or rubs on the column. If that is fine, I would replace the turbo signal switch. All of those signals go thru that switch and the contacts will get weak after while. I hope this helps with your issue. Thank you
