I have a 2003 expedition EB 5.4 with 167k miles. My stop lights suddenly quit working. I'm not a mechanic by any sense of the word but I understand the basics. I have tested the 3 fuses that I can see are related to the stop light. 2,5 & 29. I have replaced all the bulbs including the upper ones and I have installed a generic stop light switch and a genuine Ford stop light switch and still nothing!!! I also see that fuse #2 is for "stop light relay" can't find that anywhere.. any ideas.. Thanks
