Expert Answers about Dodge Grand Caravan


  • Troubleshooting Trailer 4-Way Harness that Converter Shows Constant Voltage on Left Turn/Stop
  • The converter you have is bad. If the signal going into the converter is good, but coming out of it is bad then the problem is a shorted out converter and it would need to be replaced. Before you replace it you will want to inspect the wiring of your trailer to see if you can find anything that would cause the box to short out like corrosion or cut/exposed wiring. These boxes don't usually go out unless there is a short on the trailer that takes it out. For a replacement wiring harness...

  • Troubleshooting Trailer Lights on 2008 Dodge Grand Caravan with T-One Wiring Harness # 118552
  • If you ran the power wire and have current there, before the connector, then you will need to use a circuit tester, item # PTW2993 if needed, and check each one of the other circuits going into the converter. Make sure they are functioning properly. This should be done without the trailer connected. If they are not working properly check the connections behind the taillights and the ground connection to make sure they are secure. If all connections before the converter are functioning...

  • LED Indicator Light on Curt Trailer Wiring Harness Is On All the Time On 2013 Dodge Grand Caravan
  • The Curt trailer wiring harness for the 2013 Dodge Grand Caravan is # C56331. I could not find information on a 56187. The correct harness does not have an LED indicator light on it anywhere. There are some adapters, like # C57674, that have LED indicators to tell you a circuit is working on or not. In this situation the 12 volt indicator light will always be on because the 12 volt circuit is hardwired directly to the battery. In order to not have it come on it would have to be wired to...

  • Trailer Running Lights Do Not Work with Trailer Connected to 2012 Dodge Grand Caravan
  • The way you are describing the trailer connectors on the vehicle it does not sound like a factory connector. But regardless of if it is factory or aftermarket, check to make sure there is not a loose white ground wire not connected to anything. The harness will not function fully without a proper ground. It is possible that the lights on the trailer are over drawing the ability of the trailer wiring on the 2012 Dodge Grand Caravan. If it is factory wiring then you would need to consult...

  • Can Corrosion Cause Wiring Malfunctions
  • The first thing you will want to do is replace any corroded connectors or wires that you see as this will cause your lights to malfunction. Once the corrosion is gone, test the ends on each of the poles coming from the vehicle side trailer connector for proper function while a helper activates each circuit. You can do this by using a circuit tester part # PTW2993. This should fix your problem however, if it does not, I would be glad to offer further troubleshooting advice if you can tell...

  • Troubleshooting Trailer Running Light Fuse Blowing on Truck
  • I think you have it basically nailed down and the issue is that you have a short to ground on the trailer running light circuit on the right hand side of the trailer and would need to go over the wiring to see if you can find any cut or exposed wire and fix as needed. Sealing the exposed wire with electrical tape like part # PTW502 would be all you'd need.

  • Troubleshooting Malfunctioning Trailer Lights On a 4 x 6 Utility Trailer
  • T-One harnesses are almost impossible to wire incorrectly, so I would say it is most likely somewhere in the trailer wiring. Whichever side, driver or passenger, is having trouble, start at that tail light and work your way towards the vehicle. If the light has a ground wire, make sure it has a good clean ground connection, and make sure it is touching metal and not paint. Some lights are grounded by the bolts or screws that attach the light to the frame, so make sure those are clean...

  • Troubleshooting Left Turn Signal on Trailer that Overrides Brake Lights on Right Side of Trailer
  • It sounds like you are using a universal wiring kit like the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236 on your 2015 Dodge Grand Caravan. This is a kit that you hardwire to your vehicle and it has a green wire for the right stop/turn signal, a yellow wire for the left stop/turn signal, a red wire for the stop light, a white wire for the ground, and a brown wire for the tail/running lights. If your vehicle has the stop signal combined with the turn signals...

  • Troubleshooting Vehicle Running Light Not Functioning After Trailer Wiring Install
  • Both of your vehicle taillights (the circuit on when head lights and running lights are on), are powered by the same circuit. If the T-connector being connected on the # 118376 caused the taillight to go out then I would try unplugging the connector and then replugging it back in as most likely the pins just aren't seated right. Getting this circuit to work right will also most likely allow the taillights of your trailer to start working as well. Running a jumper wire will work as a Band-Aid,...

  • Trailer Wiring Harness C56333 for a 2008 Dodge Grand Caravan Shows Power on the 4-Way All the Time
  • The Curt trailer wiring harness # C56333 for the 2008 Dodge Grand Caravan should only show power on the 4-Way when the converter receives a signal from the vehicle tail lights. Constant power indicates a short or possible bad connection. However it is also possible that a small amount of power is coming through since this is a powered converter. It would only be enough to dimly light the trailer lights, if that. If this is what you are seeing, it is normal for this harness. Make sure the...

  • Curt T-Connector No Longer Working On a 2016 Dodge Grand Caravan
  • I do have a recommendation as Curt does not offer the replacement components that you are looking for on your Curt T-Connector Vehicle Wiring Harness # C56331 for your 2016 Dodge Grand Caravan. I have noticed is not everyone secures the black converter box on their vehicle. If the box is left free it tends to become more easily damaged. For this reason it is best to use the included double-sided tape and if at all possible secure the top hole with a screw into a solid structure that will...

  • Troubleshooting Trailer Brakes Sticking
  • Your truck is not causing your trailer brakes to stick; if the brakes are sticking when you have your trailer hooked up to a truck but not another vehicle then it is possible your truck's brake controller or connector is the issue and you will need to troubleshoot it. To test the brake controller, sever the blue wire a couple inches from the back of your controller. Then use a circuit tester such as # PTW2993 to test the end of the blue wire coming out of the controller. It should only...

  • Troubleshooting T-1 Connector Part # 118552 on 2010 Dodge Grand Caravan
  • Having the signal bleed over from the drivers side to the circuit feeding the passenger side usually indicates a ground problem. Try running a jumper from the white ground wire coming off the converter to the negative battery terminal, and see if that solves your problem. If so, try using a different grounding point for the converter. If there is a factory installed grounding point nearby, that would be ideal. If no factory ground is available, try shooting the grounding screw into a pinch...

  • Trailer Brake and Turn Signals Stopped Working with Curt Trailer Wiring on 2008 Dodge Grand Caravan
  • If you are getting power when the brake or turn signals are on into the Curt wiring harness converter box for # C56333 from the vehicle BUT there is no power on the brake/turn signal pins on the output side with the 4-Way connector that indicates a problem with the converter and the whole harness will have to be replaced. There was likely a short at some point, probably when you were using the harness, caused by moisture or corrosion, even a pinched wire, and the box did what it was supposed...

  • Fixing Muffler Rattling Against Curt Class III Hitch # 13364 on 2010 Dodge Grand Caravan
  • What you describe is a fairly common occurrence. The spot where the hitch sits on the vehicle does not vary from Grand Caravans of the same model year. However, since the exhaust system uses flexible rubber isolators and muffler hangers that are easily manipulated, the exact location of the exhaust system can vary quite a bit between vehicles of the same year, make and model. We've actually come up with a help article that specifically addresses this issue (see provided link), which provides...

  • Trailer Wiring on 2013 Dodge Grand Caravan Not Working After Connecting to Miswired Trailer
  • I am assuming that you also checked the fuse for the trailer wiring harness (if it is one that requires power from the battery). If not be sure to check that one on your 2013 Dodge Grand Caravan. If the power wire fuse is still good, then what likely happened is the short was bad enough to blow the converter box. That means it did exactly what it was supposed to do; it took the hit to protect the vehicle. A noble death indeed. To test the converter, you can use a circuit tester such...

  • OL Error Code on P2 Brake Controller and 2010 Dodge Grand Caravan
  • The OL code on your Prodigy P2 brake controller indicates the brake controller senses an overload condition. Possible causes for this are a short on the electric brake wire (blue wire) or a poor ground connection. The easiest places to start looking for causes are the truck and trailer side connectors. Make sure they are both clean and free of corrosion inside where the wires attach and on the pins. Also make sure the main trailer connector grounds are attached to clean and corrosion free...

  • Options to Help Reduce Noise From an Awning with Solera Smart Arms Flapping in the Wind at Night
  • We do have something that will help. Honestly, your best option for noise reduction is to roll the awning up. That said, since your awning has the Solera Smart Arms you can add the Solera Smart Arm Wind Sensor Kit # LC715123. The Solera Smart Arm Wind Sensor Kit # LC715123 has 3 different levels of wind sensitivity, or you can completely deactivate the wind sensor altogether. This will allow you to leave your awning extended at night and if it gets too windy the awning will automatically...

  • Troubleshooting Trailer Turn Signals on 7-Way Both Having 12 Volts at all Times
  • The stoplight and blinkers circuits should not have 12 volts of power on them at all times. Typically when what you described happens it's because the 12 volt power circuit is shorting out to those circuits. If you paid someone recently to install the 7-way I would take the vehicle back and have them fix it. Another possibility is that the trailer wiring converter box that was used for the taillight circuits has shorted out due to a short on the trailer wiring. What you will want to do...

  • Troubleshooting Trailer Wiring Harness C56331 Installation in 2014 Dodge Grand Caravan
  • Thank you for your purchases from etrailer. I suggest you re-check your ground wire connection. It can happen that a weak ground will pass enough current for some light functions but not others. Turn signals that blink on and off will draw less power than the brakes, which remain illuminated as long as you step on the pedal. You can try sanding off any paint/primer that may remain on the grounding point to enable a better connection, or you can relocate the ground terminal to a new spot...
