Hello and welcome to Justanswer,Yes there is a fuse for the third break light only, it located in the under hood fuse panel and its the F12 fuse. Check it and see if its blown
Thanks fuse 12 is fine, next?
The next step if your fuse is okay it to swap the stop lamp relay with the on enext to it and see if that solves the problem, if it does then the relay is bad. See the location HERE in the under hood fuse panel.
the link does not reference fuses
No the link references the break light relay, that what I want you to try swapping with the one next to it.
Its located in the under hood fuse panel, I have marked which one it is in the link.
Thank you. Problem solved. Missing relay, empty socket. Again thank you for you help.
