Expert Answers about Jeep Liberty


  • Troubleshooting Steering Wheel That Doesn't Return to Center Around Sharp Turns When Flat Towed
  • Sounds like your tow bar may not be sitting perfectly level. If I had to guess it sounds like the tow bar is angled forward and that is causing the wheels to get stuck turned to one side. I attached a help article on how to pick out the correct high low adapter to allow the tow bar to be level as well as a link to a page that has all of the ones we carry.

  • Hitch Bolts and Cleaning for a Draw-Tite Class III Max-Frame Trailer Hitch Receiver
  • I apologize for the trouble you are experiencing with your hitch. The bolts that are supposed to come with the Draw-Tite Class III Max-Frame Trailer Hitch Receiver, part # 75128, are 12mm x 1.75mm. It sounds like you received the correct bolts. Even if your vehicle has been on the road for only a year, it is very likely there is some dirt grime in the weld nuts on your Liberty. You may want to try cleaning out the weld nuts. I would first recommend soaking the bolt holes on your frame with...

  • Troubleshooting Hopkins Plug and Play 4-Pole Trailer Wiring Harness 42475 for 2003 Jeep Liberty
  • A 4-pole wiring harness like Hopkins # 42475 combines the stop and turn light signals from the Liberty onto one wire for each side of the trailer. The green wire carries passenger side brake and turn signals and the yellow carries the same two signals for the driver side of the trailer. If you have a left brake light signal but you are finding that you do not have a left turn signal this could mean that one of the pins inside the vehicle or harness connectors is not making proper contact...

  • Troubleshooting Pinched Airline with Firestone Coil-Rite Air Springs on a 2008 Jeep Liberty
  • The hole that gets drilled into the jounce bumper mount does not have a set measurement on where it should be located. If shortening the line would prevent it from getting pinched when the suspension is lowered I would do that as that should be the easiest. Since you plan on shortening the line what you could do is cut a slit in the air line on the barbed fitting to remove the line and then cut the line to the length you want and reinsert the line. Thanks for the feedback on drilling...

  • No Turn or Brake Signals on Trailer on a Jeep Liberty with Tow Ready Harness 118524
  • The first thing to do is disconnect the trailer from the Liberty. Then using a circuit tester, like part # PTW2993, test each pin of the 4-Way. Clip the alligator clip of the circuit tester to the exposed post, the ground wire. Check each pin with the probe. The brown wire should be running lights. Yellow should be left brake and turn, and green should have the same functions but for the right side. If these functions all work, then the problem is on the trailer. If not, then the problem...

  • Testing the Running Light Circuit on a 4 Pole Trailer Connector
  • If you are not sure of the exact wiring harness you are using on your 2012 Jeep Liberty, then you could be using a wiring harness that is not compatible with your new jeep. The T-One Vehicle Wiring Harness, part # 118554 is the correct wiring harness for your vehicle. If you verified that you have the correct wiring harness, then it sounds like the converter box could have a short allowing constant power to run through the running light circuit, or the brown wire on the wiring harness...

  • Why are Trailer Tail Lights Malfunctioning When Connected to a 2003 Jeep Liberty
  • Often when you find that you get lights that are not working at all or performing strangely, the issue is a problem with the ground wire. Since the same problem occurs on two different trailers, I would suggest first checking the ground wire going into the converter box on the 4-Way wiring harness on your 2003 Jeep Liberty. This wire should be white, with a ring terminal attached. Make sure that this ground wire is firmly connected to a clean metal point on the vehicle frame, and that...

  • Recommended Replacement Brakes for 5000-lbs Horse Trailer with 15 Inch Wheels
  • If you've got 15 inch wheels on your horse trailer I believe you've likely got 12 inch brakes; you will want to confirm the capacity of your axle and the size of the hub and drums in order to make sure you get the right parts. To replace those, I recommend using the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA since they're a high quality self adjusting brake assembly; after the initial adjustments you won't need to do any...

  • Troubleshooting Trailer Wiring Issue with 2008 Jeep Liberty
  • The fact that your trailer lights seem to work just fine until the vehicle headlights are switched on indicates a ground problem somewhere in the system. The quick way to confirm a ground problem would be to disconnect your existing ground connection from the trailer and use a butt connector to temporarily connect a length of wire long enough to reach the negative battery terminal. If this temporary jumper fixes the problem (which it most likely will), you have confirmed a poor ground...

  • Brake Lights on 2009 Jeep Liberty Stay on While Driving w/ Curt T-Connector Wiring Harness Installed
  • I reached out to my contact at Curt, and they agree that it sounds like the converter box on the T-Connector Vehicle Wiring Harness, # C56334 might be bad. You can troubleshoot the converter by using a circuit tester like # PTW2993, on the input side of the converter (wires leading from the connection to the vehicle taillight harness to the converter box). Test each wire as its function is activated- red wire = brake lamps, brown wire = running lamps, yellow wire = left turn and green wire...

  • Left Turn Signal Activates Both Tail Lights on Trailer
  • The most likely cause for both of the turn signals to flash when activating just the left signal is a bad or weak ground. A weak ground connection can cause a variety of strange things to happen with the trailer tail lights. I recommend checking that both the vehicle and trailer side connectors are free of any dirt or corrosion and simply clean as needed. Also make sure that the main ground is connected to a clean, bare metal surface on the trailer. Then check to make sure the trailer...

  • Tail Lights no Longer Working on a 2003 Jeep Liberty After Installing Universal Taillight Converter
  • It could be a blown fuse on the tail light circuit. If the vehicle has no tail lights, when trailer disconnected, a blow fuse is the most likely culprit. Check for any towing light or tail light circuits on your fuse blocks and see if you cannot find a burned fuse. If I knew which universal converter you installed, I may be able to provide some more trouble shooting

  • Troubleshooting Brake Lights Not Working on Trailer with 2003 Jeep Liberty
  • I am not quite sure what wiring kit you used to install a 4-Way connector on your 2003 Jeep Liberty but it sounds like it may not have come with a converter. Your Jeep Liberty has a separate wiring system, which means the brake and turn signals are sent along separate wires. A harness with a converter is needed to combine these circuits so that they work with standard trailer wiring. For example the Curt T-Connector Vehicle Wiring Harness # C55382, which is custom-fit for your 2003 Jeep...

  • Tips for Wiring a 2009 Volkswagen Jetta Wolfsburg Edition with a 4-Way Trailer Wiring Harness
  • What it seems to boil down to is if the vehicle has a 2 wire system or a 3 wire system. On a 2 wire system, you would ground the red wire with the white wire. This is because the stop and turn signal lights are combined on one circuit. On a 3 wire system, the turn signals are separate from the stop light so the wire needs to be connected to the dedicated brake light wire. What it sounds like is that the running light brown wire is getting connected to the wrong wire on the vehicle. VW...

  • Troubleshooting Inconsistent Tail Light Functions for Flat Towing 2004 Jeep Liberty
  • Since you installed the wiring on your 2004 Jeep Liberty a few years ago but never used it then the first thing to do is apply 12V power to each pin on the front of your Liberty to see if the lights function like they should. If they do then you know the problem is on your motorhome but if they don't then the problem lies with the wiring on your Liberty. Regardless which side it's on you'll want to use a circuit tester to test along the wiring to see where the signal gets lost. Making...

  • Troubleshooting Trailer Lights That Go Out When Headlights Are On in 2012 Jeep Liberty
  • The most common cause for some trailer lights to work but then to go off when another function is activated is a bad ground connection. A weak ground wire from your vehicle's 7-way to the car's frame can allow certain functions to operate until a higher-current item, such as your headlights/running lights, are turned on. This load is then too much for the weak ground connection and some or all functions will go off. The first thing to check is the white ground wire leading from the Jeep's...

  • No Power To 4-Way With Curt T-Connector Vehicle Wiring Harness On a 2003 Jeep Liberty
  • There are only two possible issues that could cause the Curt T-Connector Vehicle Wiring Harness part # C55382 which is a fit for a 2003 Jeep Liberty not to function correctly. The first is that the pins inside each of the t-connectors are not perfectly seated whether that be from the pins being bent or just not fully engaged so be sure to check that. The next is as you mentioned a bad ground. Please note, you need bare metal contact with the ground wire so be sure you have sanded some of...

  • Correct Trailer Wiring Harness for 2012 Jeep Liberty
  • To install the # 118384, you would need to unplug your existing 7-way harness from the rear of the socket. The # 118384 would plug inline between the vehicle harness and the existing 7-way, as shown in the video I linked you to. If your Liberty does NOT have the factory tow package with the 7-way trailer connector, the connector that the # 118384 would connect to will NOT be present. In this case, you would need part # 118554. I have linked you to the installation instructions for the...

  • Troubleshooting Tail Light and Brake Light Issue When Using T-One Vehicle Wiring Harness # 118524
  • To pinpoint where the problem is actually occurring, I recommend using a circuit tester to check for function at the 4-Way plug on your 2007 Jeep Liberty, without your trailer connected. We offer part # PTW2993, if needed. With a helper in the cab of the vehicle and the taillights on, check to see if you get a power reading on the yellow and green wire ports when the turn signal is flipped or the brake pedal is pressed, as these would be the turn and brake signal wires. For example,...

  • What Should Display on Primus IQ Trailer Brake Controller # TK90160 Show When Manual Button Pressed
  • A trailer brake controller like the Tekonsha Primus IQ # TK90160 will apply the brakes when you press the manual override lever with the same force as when you press the pedal. This force will be determined by the chosen power level and boost setting. The display message .C indicates that the controller has power, senses a connected trailer but does not have the boost feature engaged. When you engage the boost another dot will appear and you will see .C. When you press the manual lever...
