06 Liberty tail light problem?

Ok, so our 06' Liberty has this annoying problem with the passenger's side tail light, the stop/night light's socket that connects directly to the metal pin on the red lamp assembly doesn't make contact so occasionally, I either have my stop/night light working correctly or I have either just the stop or just the night light working, last night I only had my stop light working and not the night light, so this morning I tried to adjust the socket to make contact with the metal part on the red lamp assembly and it kind of worked and it was working properly, however tonight I drove again and I had just the stop working and not the night light!! But here comes the weird part that never happened before, the interior lights that illuminate the cluster, the radio and the PRND12 bezel were off and they would only illuminate when I applied my brakes. Does anybody know what the heck is wrong with our Liberty and why my dashboard lights only illuminate while pressing the brake pedal? By the way, all light bulbs are new so it's not that.

I would suggest that you replace the socket assembly as that is where the problem is coming from.
You do get weird symptoms sometimes if you have bad earthing...replace the unit first and see what happens.

Yeah,the dashboard lights problem was just a blown fuse, this fuse shares the dash lights with the rear pass. side parking light so that was the problem, I also had to adjust a little the socket to get contact, I think I'm going to have to replace the whole tail light assembly in the future since where the socket goes it is a little burned and this causes to mess up my lights, I'll just leave it until it stops completely working.

tail light wiring issue

Hi there! I have a 2003 Jeep Liberty Renegade. My right tail light is out but all other lights work. The bulb is good, the socket is good, the connection is good, and the fuse is good. The problem seems to be stemming from the wiring. Somewhere in the wiring from the fuse to the bulb there is a disturbance in power. We used an ammeter and the amps at the fuse were 11 but at the bulb they were 0. Any suggestions on what could be the cause or how to fix it? Thanks!

Start by getting the wiring diagram, then your going to have to trace the wires back to the fuse box. Has any trim around the doors been coming up, have you put anything very heavy in the rear compartment that may have crushed the wires, anything electrical been hooked up prior to this say a week before?

I think you mean that volts at the fuse were 11 volts but at the bulb were 0 volts and that you used a voltmeter....not trying to be a smartyass here but we need to get the basics right first.

If you look at the attached circuit diagram for the 2003 KJ....no specific mention of Renegade or not...you need to put your Multimeter on DC volts and measure at on both sides of Fuse 9 (10 A) on the Junction Block which is the internal fuse panel. This is with reference to a good ground somewhere such as a clean chassis or engine point.

You should read approx 12 volts here...11 volts is no big deal.
Then the voltage leaves the Junction Block on connector C2 Pin 26 via a Dark Green/Yellow wire. Pull this connector C2 off and re-plug it a few times in case you have a dirty connection here.

This Dark Green/yellow wire then goes through connector C306 Pin 16.....white connector, left lower B-Pillar...check this connector is clean and tight.

It then goes through connector C310 pin 11, Light Gray connector, right rear quarter panel and to pin 2 on the tail-light cluster....so you should read +12 volts here at the cluster where the Tail Light bulb plugs in....with reference to the ground connector at the cluster socket namely where the Black/White wire goes. If you do not read +12 volts here....with the lights switched ON of course...then move the ground lead of your meter to a good chassis point or the rear axle etc. If you now read +12 volts it means that the ground has gone missing to the socket but I believe on your USA model the Tail Light/ Stop Lamp share the same bulb or at least the same ground but I may be wrong here!

So you need to trace where the voltage has gone missing but common problems are the bulb, the bulb socket, the ground going to the bulb or...if you have a non-Mopar trailer package installed then a problem with the trailer package.

You can test for the presence of +12 volts all the way along the route of the Dark Green/Yellow wire by piecing the insulation of the wire at various places with a pin or sewing needle to contact the copper conductor and place the positive meter lead on the pin to check for voltage....close up the pin-hole in the insulation with some glue afterwards.
