brake lights not working, upper light works?
Jeep Liberty 2006 Ltd. Rear brake lights are not working. The third (upper)
brake light is working. I checked the bulbs and fuses and they are ok. All other
lights work. What could be the cause of this problem.
I have the same problem. What was your solution?
Same with me, did you figure it out?
After researching further online some posts suggested it is the multifunction switch on the steering column. Apparently there is a circuit that goes through the turn signals to dim the brake light as the directional is on. Haven't replaced it yet, gonna check with meter to see if that is it first.
Has anyone tried replacing this component to see if it is the solution? Also if anyone could include a picture of the part that would be helpful
Nicholas, I replaced the turn signal switch/multifunction switch. Nothing happens. I still have the third brake light and no brake lights.
I found that the connection between the taillight and the socket are dirty clean them with sandpaper brake lights work fine
I was checking the pins with a multimeter for ground and continuity and found the light started working. I went to the other side and just cleaned the contacts on the plug that that connects to the assembly the holds all three bulbs and bingo it started to work. So the issue is dirty or corroded contacts.
Update... better late than never. I swapped bulbs from back up light sockets to upper tail/brake sockets and replaced the lower backup bulbs on both sides. It worked! None of the bulbs appeared spent, so I have no explanation. All good...just replace bulbs
