Well, today the MHP politely told me that my tail and running lights are not working. This is on my 84 W150. The turn signals and brake lights are working and they work on my trailer also. All of my fuses seem to be good. (checked for blown on the side of the road with the help? of the trooper) OK according to my owners manual there I no fuse for these, but I do not know how to find the relay. Any Ideas on this would be greatly appreciated.
I didn't find the right solution from the Internet.
