This vehicle is equipped with the following printed circuit board PCB mounted relays.
• High beam
• Low beam
• Fog lamp
• Park lamp
• Stop lamp
• Horn relay
They are directly soldered to the underhood fuseblock circuit board. A failure of one of these relays will require the whole under hood fuse block to be replaced.
Turn Signal/Hazard Lamps
The body control module (BCM) is responsible for controlling the turn signals and hazard lamps. When the turn signal switch is placed in either the left turn or right turn position, the BCM receives a signal from the turn signal switch. The BCM then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, the BCM receives a signal from the hazard switch. The BCM then will send an on-off voltage signal to all the turn signal lamps. All the turn signal lamps will flash including both IPC turn signal indicators.
Vehicles are just not the same as they use to be. Electronics !!!!!
fuse labelled 'F1R' which is 20A and dedicated to the rear fog lamps. Interestingly it looks like this same fuse also is responsible for all the rear brake lights. If they don't work either, then this is the culprit. If they do, then work back from the rear cluster assembly to check for faults. Firstly, the wires to the fog lamp should be white (live) and black (earth). The only other difference I can spot is that they do NOT share the same earthing point. They are labelled on the diagram as E8 (brakes) and E7 (fog lamp). The earth point is maybe a grey wire on the right hand tailgate /might be the other side on left hand drives. It may be loose or corroded. Switch on fog lamp and use a multimeter to check the earthing and if voltage is present.
are you talking Parking lights. all lamps work? cept one?
there are park(tail-running) blinker, brake, and fog.
my guess is side lamp means the actual car side parking lamps/.
there are huge numbers of lamps for park inside and out.
like 20, the inside lamps are DIMMable.
if all 20 odd lamps glow and one dont, it can only be.:
1: bad lamp.
2: bad socket to lamp
3: wires cut to said socket.
i use a thing called a voltmeter to see what part is bad.
got one,? $10 at walfart?
You have a short to ground somewhere in the drl-fog lamp circuit. Check for obvious wiring connector or wiring to drl & fog lamps. check wiring for pinched or broken wires coming from sockets. If you don't find problem, you can trace wiring from lamps to main harnesses and hopefully find source of short.
hope this helps.
I have notice that this is a common problem. The socket most of the time goes bad, I don't know why but they just do. You can pick them up at any parts store for around 5.00 each. If you don't have a volt meter and ground straps to test it right, then I would try changing the sockets out. Quick and easy. Let us know how it goes.
Should still be under warranty. If you have determined it is not a burned out bulb, let the dealer trouble shoot.
Some other things to check, from a wiring standpoint, does the right side emergency flasher work? Does the right side backup light work?
If these do not, I'd look for a connector to the right side of the rear that came loose. Haven't spent that much time under my 2009 (same model style), but I'd suspect on a jeep that physically following the wires to a connector would not be hard. Also could be a ground issue to the right side lamp housing.
I can't look up your wiring diagram because I don't know model year?
On some makes and models, the lower brake lites are wired through the multifunction switch. Your turn and stop use the same bulb filament, just not at the same time. On a left turn, the left turn signal works, but the brake lite on the left doesn't. Now, the brake lamp on the right does work. The high mount brake lite also will work. The highmount brake lite is usually wired differently than the lower brake lites.
W/o being able to look at wiring diagram, I don't know if my info is applicable on your vehicle? I need model year.
