  • Troubleshooting A Furrion Vision S Camera System That Intermittently Loses Connectivity
  • If you installed the PWM Filter # VGR64VR on your Furrion Camera System # FOS05TASF and you're still having issues then I recommend unpairing the camera and monitor and redoing the pairing process. I also recommend checking the antenna and ensuring that it's fully screwed into the camera and facing up. With a 492' range it shouldn't really matter but it's worth trying. Is the camera only powering on and connecting when in reverse or is it just randomly connecting while driving around?...

  • Troubleshooting LED Trailer Lights Causing Error Code On 2021 GMC Sierra Denali 2500
  • To correct the issue the couple is having powering LED trailer lights with their 2020 GMC Sierra Denali 2500 I recommend going with the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass # 20142 due to it being a simple plug and play adapter that installs in the vehicle's 7-way connector and you simply plug the trailer's 7-way connector into it. The built in system will prevent the issues you are having and will allow you to move the adapter to a different vehicle if needed. The Optronics...

  • Removing Damaged Curt Gooseneck Hitch Ball From Factory In Bed Hitch System On a 2020 GMC 2500
  • If you still have a portion of the latch for the Curt Pop-In Ball # C60629 protruding out of the top of the ball you can try to grab it with pliers, pull up and rotate it to unlock the ball bearings. Depending on how long the ball has been in the bed there may be some surface rust inside the ball which would make it difficult to operate. You can spray some penetrating oil in the ball to try and free the ball. If there is not part of the latch visible from the top you will need to go below...

  • Troubleshooting Brake Controller not Working Except With Manual Override
  • I'm not sure which brake controller you purchased from us that you're referring to, though when a controller won't work except when using the manual override the issue is often on the red wire - the stop light wire - which sends a signal to the brake controller. You'll need to use circuit tester # PTW2979 to test the stop light switch wire, which is the wire that only gets power when you step on the brake pedal. If it does not have power then you likely have a blown fuse that you'll need...

  • How to Fix Backfeed From Trailer Battery and Solar Controller on 2024 GMC Sierra 2500
  • Installation of the # RM-790 will take care of that problem you're having. I would wire it on the trailer side at the battery rather than mess with the wiring on your 2024 Sierra 2500. The other solution is to follow the GM note and add a disconnect between the battery and solar controller like other trailer manufacturers have started to do. If you want to go that route you can use the # SE29VR.

  • Troubleshooting An LF Error Code On A Lippert Ground Control 3.0 Leveling System
  • An LF error with your Ground Control 3.0 system # LC358590 would indicate an issue with the left front leg. The first step in solving this issue is going to be checking for power. Start by plugging your trailer in to shore power, the most common issue with this system is that it requires 12.75 volts in order to operate and a lot of the time the trailer battery dips just below this. Next check the fuse for the left front leg at the control module # LC304136 for power to ensure it's not...

  • Interior Lights On A Hawk Trailer Pulled By A 2021 GMC Sierra 2500 Not Working
  • The number 63 fuse is the correct fuse to check on your 2021 GMC Sierra 2500, and it should be your trailer battery circuit. Since you said you checked out the #63 fuse, and it's all good, I recommend checking your 7-way connector/receptacle. You'll want to ensure that your connectors are free from debris and not corroded. You'll then want to use a circuit tester like the Hook Probe Circuit Tester # PTW2993 to test for continuity at the 1 o'clock position on your vehicle side 7-way connector. Or Even...

  • Troubleshooting No Running Lights on 4-Way Connector Spliced Into 7-Way on 2017 GMC Sierra
  • It is completely possible to have gained the functions of your turn and stop lights and tapped into the wrong wire for running lights. The wire you want to tap into for your running lights is in the 11 o'clock position as you look at the outside of the connector (or the 1 o'clock position when viewing the back of the connector. I've attached a photo to assist that includes colors, but go off of function location if the colors don't match up. If in doubt, use a circuit tester like # PTW2993...

  • How To Secure The SM Arnold RV Chenille Microfiber Wash Mop Head To the Handle
  • The mop head for the SM Arnold RV Chenille Microfiber Wash Mop # 38185-332 is a rubber material with a slot that matches up and holds the ring at the end of the handle to the mop head. Since there isn't a bolt to tighten these too items together the only way to really secure it would be to drill a hole through the rubber boot and through the handle itself and slip a carriage bolt through and secure it with a nut.

  • B&W Companion 5TH Wheel Hitch, Drivers Side Jaw Won't Open
  • I recommend using some penetrating lubricant on the drivers side jaws of the B&W Companion OEM 5th Wheel Hitch # BWRVK3700. The passenger side is forced open by the cam in the handle. My guess is that the jaw may have some surface rust or corrosion that has caused it to stick. If you are unable to get the jaws to work properly a Replacement Head Assembly # BWRVC3006 can be obtained. This will give you a virtually brand new hitch.

  • Troubleshooting No Braking Power from Foot Brake to Trailer Brakes on 2015 GMC 2500
  • I recommend using a circuit tester like # PTW2993 to check the red wire on your brake controller to ensure you are getting power from your brake light switch to your controller. If you are getting power, then you will want to check the adjustment settings on your controller. If you are testing your controller when your vehicle is stopped, you will not get a reading from the brake pedal because it is a proportional controller and no trailer braking is needed if you are not moving. The...

  • Solution for Draw-tite Front Mount Hitch Not Fitting With Slight Gap
  • Sometimes hitches can get slightly bent during shipping and this can be fixed by bending the hitch back into place as long as the hitch only has a slight bend to it. If yours isn't lining up I can almost guarantee that is what happened. Some people will use open steps for leverage, vices and even car jacks to apply controlled force to bend the hitch back. In your case you could start all of the bolts and then torque them all down to allow the hitch to bend back into place. You will want...

  • Troubleshooting LED Trailer Running Lights Randomly Turning Off On 2020 GMC Sierra Denali 2500
  • There is a connector that some vehicle's require to use LED trailer lights which is # C35FR for 7-way to 5-way/4-way or # 20142 for 7-way to 7-way. The way you would know if you need one of these adapters is your vehicle would display an error code when plug in to the trailer due to LED lights having such a low amp draw compared to incondessiant lights. Since your running lights are working sometimes and you did not mention an error code in the truck I suspect you have a different issue...

  • Troubleshooting Trailer Wiring when 2015 GMC Sierra DIC Message Says To Check Trailer Wiring
  • Based on my research and information from the 2015 GMC Sierra 2500's owner's manual, the "check trailer wiring" message means that either a trailer with electric brakes has disconnected from the Sierra, or there is a short in the wiring to the trailer's electric brakes. The owner's manual says that when this message appears, it means there is not longer power running to the trailer brakes. You will want to check the wiring on both the vehicle and trailer that leads to the trailer's electric...

  • What Would Cause Brand New Trailers Brakes to Feel Weak
  • How far did you adjust them? Since some adjustment helped noticeably it would seem that more adjustment would get you where you need to be. Typically you want to tighten them until there's a noticeable drag that you can hear as you turn the wheel by hand. It's also possible the brake assemblies are self-adjusting which would mean that with every application they'll click tighter and tighter until they are fully adjusted and would be as powerful as you'd need. What brake controller are you...

  • Troubleshooting Aries ActionTrac Motorized Running Board Not Working On Passenger Side
  • As you only have the passenger side not working it sounds like their is either damage to the wiring or the step motor. First you will want to use a Test Light # PTW2993 to check for power on the harness of the Aries ActionTrac Motorized Running Boards # AA3047902. If you do not have power at the motor then you will need to follow along the harness to the control board checking for where it loses power. If there is still no power at the control board check the connector to ensure it is not...

  • Choosing the Correct Adjustable Shank for Weight Distribution System On a 2019 GMC Sierra 2500
  • It sounds like the shank on the weight distribution system you have does not offer enough drop adjustment, which is causing your trailer to not be level. Depending on the weight distribution system you have you can purchase a different shank like the Curt Weight Distribution Shank # 17120 that will allow up to 5-3/4 inch drop for a trunnion system to help get your trailer level. I included an article that goes over how to measure for the correct rise/drop for your setup. If you can...

  • Troubleshooting Factory Brake Controller in 2015 GMC Sierra 2500HD
  • Some factory trailer brake controllers are not compatible with trailers that use an electric-over-hydraulic actuator such as # HBA-10. Aftermarket controllers like the excellent Tekonsha Prodigy P3 # 90195 include a setting to allow for proper operation with this type of set-up, or with standard electric drum brakes. In your 2015 Sierra 2500 the P3 can be installed simply, using the custom wiring adapter # 3016 that plugs in under the dash. If you do not have an EOH actuator, but instead...
