Medium and Heavy Trucks
Have Truck Repair Questions? Ask an Expert
Hi, my name is ***** ***** I will help you today.
I want you to check the fuses in the fuse & relay center. There should be 5 fuses related to the Light control module. I want you to see if any of them are blown or loose in their sockets.If a fuse is blown replace it and try them again. If fuse blows again you have a bad wiring condition and needs futher diag by an electrition at a dealership. If they are good then I will need the build date of the truck, That is listed on the drivers door jamb on the rear side and above the door latch. It will show the month and year built. I need that to look at a schematic for the switch for the trun signals.
I hope this helps and please rate my work for today.
Thank you, Doug.
