Jason Chernoff Posted July 5 Share Posted July 5 Truck sits for a couple days and headlights or daytime running lights come on by themselves. Cannot shut them off unless disconnect battery. Reconnect cables and lights go off for a couple more days Quote Link to comment Share on other sites More sharing options...

Jason Chernoff Posted July 19 Author Share Posted July 19 Ok. Pulled relay and they quit coming on. I’ll start by changing that. Thanks. 1 Quote Link to comment Share on other sites More sharing options...
Mackpro Posted July 19 Share Posted July 19 I believe that year they look for the parking brake signal from the parking brake switch above the throttle pedal. Is the parking brake light on in the dash when your air brake buttons are pulled out? Quote Link to comment Share on other sites More sharing options...
