None of my brake lights are working, including the top-mounted brake light on the back glass. I've replaced the bulbs and fuses #7, #9 and #12 with no luck. Turn signals/hazard lights work just fine.
After searching the forum for similar issues, I determined that it's probably a faulty brake light switch or a grounding issue with the wiring running to the assembly. I ordered a brake light switch online, but I've no idea how to install it when it arrives and only a vague idea of where it's located. So my questions are as follows:
1. Can someone post a guide on how to replace the brake light switch, starting with exactly where it's located?
2. If the switch is not the problem, how exactly would I go about testing the wire with a multimeter from the switch to the brake light assemblies? How would I test the full length of the wire seeing as how the wires are concealed inside the vehicle? Would I need to pop off multiple pieces inside the Jeep to access the wire at various points?
I'm a complete rookie at the wiring thing, so if the brake light switch replacement doesn't work, I may just end up taking it to my mechanic. I'd like to try and repair it by myself first, though, regardless of what the problem is.
