Hi I have one of our tow trucks that has lost cruise control and the exhaust brake function I think they both quit at the same time I checked the basics fuses and wiring look ok pulled the switchs out and they feel alright I do not see the cruise light come on also no codes with the prolink except a left rear abs code I do not have a way to look at the switchs if they are working any ideas would be of great help thanks ahead of time
