Came out from the store and hopped in the truck. Service advance track light is on, right side ( radio buttons on steering wheel ) dont work, wipers only work on high. not low or delay. High/ low beams dont work, fog lights dont work, turn signals dont work. Now when I get out of the truck and lock it the dash chime keeps jingling and the driving lights, and running lights wont shut off. Everything else seems to work fine. Truck runs and drives just fine. Battery voltage is 12.5 on each. Truck is a 2012 Lariat with 115k on it. Is there a fuse or a device that controls all these functions I can look at for the problem?

 

 

thank you for the reply. I have been working all those connectors with no luck. I dont really use the parking brake, and I dont think its been pushed for probably 2 years. I will take another run at those connectors.

 

Just a follow up. I did not replace any parts, but the problem is fixed. For some reason when I disconnected the Ground from the battery to a 500 amp relay I have all the problems went away and its back to normal. The relay on or off didnt make a difference, just disconnecting the ground. I am going to add a grounding block and a few ground straps to the truck and hook the Relay back up this weekend. I must have a poor chassis ground somewhere on the truck.
