  • Solution for Threaded Hitch Pin that Won't Thread into Bike Rack
  • The anti-rattle device part # HE6001 that you referenced has been confirmed as a fit for your Advantage SportsRack glideAWAY Bike Rack.

  • Troubleshooting Trailer Brake Controller that Stopped Working
  • What does the brake controller show in your vehicle? Does it look like it's powering on? If not, check wiring of it and fuses related to it. If so, then I would try cleaning pins of the 7-way connector on the truck and trailer as it's most likely just a dirty pin that's preventing connection and activation.

  • Troubleshooting Trailer Lights that Dont Work When Headlights are On
  • The problem you are having is a classic ground issue. If the ground wire to the trailer frame or the tail light grounds are not connected securely to clean, rust and paint free surfaces then when the headlights are turned on the extra amperage draw for the running lights will cause all sorts of lighting issues. I would start by removing the ground wire at the trailer coupler and cleaning up the connection point and re-securing it to the trailer frame. Next I would check the ground connection...

  • Brake Lights and Turn Signals Are Not Working on Utility Trailer
  • When trailer lights are malfunctioning, there are many possible causes. As a first step, you will want to use a circuit tester such as part # PTW2993 and test the trailer connector on your Grand Cherokee. This will help you determine if the problem exists with the trailer or with the vehicle. Test each pin as its function is activated. If you are not getting current at the right or left turn/brake light pins, you will want to check the tow package fuses if your Grand Cherokee was equipped...

  • Troubleshooting 7-Way Install on a 2012 Jeep Grand Cherokee that Blinkers Dont Work
  • What you can do is test the pins of the wiring harness that you plugged the # 20119 into on your 2012 Jeep Grand Cherokee with a circuit tester like part # PTW2993 to test for voltage when the turn signals are on. If you can't find any pins on the connector that show intermittent voltage when the blinkers are on then it most likely is a programming issue you would need to take the vehicle to a Jeep dealer for.

  • What To Check When Trailer Lights Are Not Working After Connecting To A 2014 Jeep Grand Cherokee
  • If you are getting power to everything on the vehicle side, you will need to check a few things on the trailer. First and foremost will be the grounds. This should be done for every light and if they are LED lights, each should have its own designated ground connection that is not stacked with other grounds. This is a fairly common practice, but can cause some issues and it is better for each ground to have its own connection. Next you will need to check the wires coming out of the 7 Way...

  • Rattling TV Wall Mount in Winnebago Journey
  • Yes, the MORryde Wall RV TV Mount - Fixed item # MR28ZR has a lot of movement in it based on how you have to install it. I have linked a video and if you watch it around the 1:44 mark you will see how the top connection point between the wall mount and the tv bracket is a simple hinge that is not bolted together like the bottom. This will provide a lot of side by side movement that causes rattling when your Winnebago is driving down the road. Throughout the video you can hear it rattling...

  • Trailer Tail Lights Come On for a Few Seconds then Shut Off with a 1996 Jeep Grand Cherokee
  • There could be a few reasons why this is happening. The first thing I want you to do is go ahead and disconnect the trailer. Then use a circuit tester, like # PTW2979 if needed, to test the wires leading into the converter box for harness # 118349. Run through all the functions of the vehicle (left/right turn signals, brake lights, and running lights) while testing the wires. If the signals are not correct going in there that indicates a problem with the vehicle wiring that will need to...

  • Locating and Repairing Ground Problem in Wiring of Boat Trailer
  • It sounds like you are on the right track with the ground problem. Check your trailer connector on the Grand Cherokee, and make sure the white wire is grounded to the frame of the vehicle. Even though your trailer works fine when connected to your truck, you still might have a weak ground on the trailer. It is not unheard of that a given trailer will work fine with one vehicle, but not with another. Check the grounding point where the white wire from the connector attaches to the trailer...

  • Troubleshooting Curt TriFlex Brake Controller Showing Flashing DC And Locking Brakes
  • I reached out to my contact at Curt and the DC flashing on your Curt TriFlex Trailer Brake Controller # C24VV is showing that your trailer is disconnected from the brake controller. This code is telling you that there is an issue between the contoller and your trailer brakes, that there is a short somewhere. This could be corrosion at the connection, a nick in the wire somewhere or a short on the trailer itself. I recommend checking your controller first. Using an incandescent circuit...

  • Troubleshooting Low Voltage At AC Inlet On A Mini AC/DC Panel And Converter/Smart Charger
  • Low voltage at the AC power inlet but not at the outlet would indicate you have a wiring issue. I would first check the wiring for any damage or bends in the wiring and if no damage is present then you need to upgrade the wire gauge used to negate the voltage drop. I have attached a chart to help you determine the gauge needed depending on the length your wire is being ran. If this doesn't not solve your issue please reply back and we can keep troubleshooting.

  • No Power to the 12 Volt Pin on a 7-way Trailer Plug on a 2001 Ford F-250 7.3L Powerstroke
  • I looked up your owner's manual online and the 12V power issue is likely a fuse issue. You will want to check the 30amp fuse number 16. This will be in the power distribution box under the hood.

  • All Trailer Lights Work Except for Brake Lights Towed by a 2004 Jeep Grand Cherokee
  • Trailers in the US have combined brake lights and turn signals meaning the brake light signals and turn signals are sent on the same wire, one on each side. Since the turn signals are working that indicates to me that you potentially have a blown stop light of CHMSL fuse (CHMSL stands for center high mount stop lamp). It could also be a fuse or relay associated with the tow package wiring. You will need to use the vehicle owners manual to find the fuse and/or relay locations for the stop...

  • 2011 Jeep Grand Cherokee No Lights After Wiring Harness Install
  • It's pretty common on the 2011 Jeep Grand Cherokee to have the dealer activate the tow package port due to trailer lights not working after the installation of a trailer wiring harness like a Reese Multi-Plug Wiring Harness for Factory Tow Package part # 74682. The fuses are always the first thing to check but if you still don't have proper function you will need to take the vehicle into the dealer for service.
