  • How to Ease Unhitching of Sidewinder Pin Box from Reese 16K Hitch
  • The pivoting turret portion of a Sidewinder pin box like # RP61422 should not be loose enough for you to rotate the pin box by hand. This would actually indicate a problem. If you are having trouble unhitching your Sidewinder from your 5th wheel hitch I suggest making sure you have both truck and trailer on level ground and in a straight line with each other. This tends to reduce any tension between the king pin and hitch jaws that could make it hard to unhitch the trailer. You may also...

  • Fan-Tastic Vent Rain Sensor Light Stays On All the Time
  • The rain sensor doesn't have to be activated. When it gets wet it will automatically close the vent lid. When it dries it opens back up. But it sounds like yours has a short that is causing that light to stay on all the time. In order to get the replacement rain sensor you would need upgrade kit # FV803358 which includes the sensor.

  • Troubleshooting Weak Trailer Braking with Curt Tri-Flex C24VV
  • Thank you for purchasing your Curt Tri-Flex trailer brake controller # C24VV and matching wiring adapter # C51322 for your 2009 Lincoln Navigator. I am sorry you are having an issue with the trailer braking power being weak. If your voltage readings are taken on the trailer at the brake assemblies, and you are reading 12V there, then chances are that the issue is on the trailer side. The pad tension, which is set with the star wheel adjuster, should be set so that with the trailer jacked...

  • Round Weight Distribution Bar Will Not Release from Head
  • It sounds like that one bar is bound up a little. You may need to sort of lift it up and down to get it unstuck. Or you may need to take the little clip off and pull out the pin that keeps the bar in the head. Who is the manufacturer of the system you have? I can check to see if there are any known issues and remedies for this particular issue.

  • Troubleshooting Inside Sidewall Premature Wear on Tandem Axle Utility Trailer Tires
  • The axles on your trailer should not be sliding side to side enough for you to notice. There may be the slightest of side to side motion due to the various suspension components, but the majority of the motion will be up and down. If your axles are moving side to side enough that you notice then you need to get your trailer to a shop as soon as possible and get your suspension checked out. If the inside sidewall of your tires are wearing down quicker than the rest of your tires then your...

  • Replacement RV Roof Vents with Rain Sensor or Rain Shield
  • The roof vents that have the rain sensor feature (to enable automatic closing of the vent when it rains) are not serviceable. The rain sensor element is integrated into the vent/fan. As for the wall control panel in your RV you will want to speak to the manufacturer (have your VIN handy) since we do not have information on such OEM switch setups. If you want to replace the vent unit you might consider the MaxxAir # MA00-07000K which has a rain shield, or the MaxxAir Plus # MA00-04500K,...

  • Troubleshooting Trailer Brake Controller and Trailer Brakes for Correct Power
  • It sounds like you are testing the brake output at the 5 o'clock pin of your 7-way when you are hitting your brake pedal. If you have a proportional brake controller, that will not give you the accurate reading because you are not moving, the brake controller will not send extra braking power to the trailer. That style brake controller senses deceleration and provides braking voltage accordingly. The way to test that is to use the manual override on your controller. If you don't have...

  • Troubleshooting Toad Supplemental Breaking System when using Tow Haul in Winnebago Vista Motorhome
  • It sounds like the Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 locked up your brakes if you had flat spots on your tires. This is most likely the system sensing the deceleration and braking and because of the steep grade kept applying the brakes sensing it needed to help stop your motorhome. I reached out to my contact at Roadmaster and they confirmed that the Accelerometer was continuing to apply braking because it was sensing that brakes were needed. It appears...

  • Troubleshooting Trailer Light Fuse that Keeps Blowing in a 2016 Toyota Sienna
  • A 30 amp fuse will likely fix the problem of the fuse blowing but fuses are meant to safeguard against wiring overheating it would be dangerous to do so and could result in a fire. It sounds like you simply have a short somewhere. Start off by checking the connector on your 2016 Toyota Sienna and your trailer. Clean out any debris or corrosion and apply some dielectric grease like part # 11755 to help keep them clean and protected. If your connectors look good then you need to check the...

  • Troubleshooting Right Rear Trailer Light With Running Light Overpowering Brake and Turn
  • It sounds like there is a short within the tail light since this is only an issue on the right rear tail light assembly. If you test the wiring using a circuit tester like # PTW2993 just prior to the tail light, does everything work correctly? If so, then you have an internal issue that could be a bulb, or wiring issue. However, if you have the same issue when testing the wires prior to the unit, then you are getting too much power from the running light wiring on that side and you...

  • Unable to Lower Power Level on Tekonsha Primus IQ Brake Controller
  • It sounds like something is drawing full power on the brake output of your Tekonsha Primus IQ Brake Controller # TK90160. This is most likely the reason why the display is showing 12. According to the User Manual, the power output range is from 0.0 to 13. To determine the cause we'll need to test a few things. Start by severing the blue wire coming out the back of your Primus IQ, leaving a few inches of wire to reconnect later. Use a circuit tester like # PTW2993 to check for power. The...

  • Troubleshooting Only One Side of Trailer Brakes Locking Up
  • Yes, when the electric signal is sent from the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 to the trailer's brakes, it should cause both sides to lock up. Since only one side is locking up, it could indicate that one brake assembly needs to be manually adjusted. I attached a video that shows how to do this process. If that doesn't get it to respond then there is possibly an issue with the wiring going into the brake assembly which you can test using a circuit tester like # PTW2993....

  • Troubleshooting Brake Controller Wiring of 2005 Chevy Silverado Not Working with Brake Pedal
  • For your generation of Chevy truck the issue you are having is almost always the third brake light fuse being blown. When this circuit is dead it also kills the brake controller wiring circuit that shows voltage when the brakes are applied. Try pressing the brake and seeing if the third brake light above the cab comes on and replace the fuse as needed.

  • No Trailer Turn Signals After Installing New Tail Lights
  • The first step for troubleshooting the trailer turn signal lights is to test the vehicle side connector. If you are not getting any power on this circuit then you will need to check the fuse box for any blown fuses. If you have an aftermarket trailer wiring harness then test the turn signal wires before and after the converter box to ensure the signal is both entering and leaving. Finally, check the ground for the vehicle side trailer connector. If you do get power to the vehicle side...

  • Fuses Look Good But No Power to Trailer Plug on 2014 Ram 3500
  • If you aren't getting power back to the trailer plug on your 2014 Ram 3500 but your fuses all look good then you can either trace the OEM wiring and look for any places where it is damaged (replacing as necessary) or you can bypass it with something like the Tekonsha # 119250KIT and the Universal Wiring Kit # ETBC7. Aside from those options the only other thing you can do is take your Ram to a dealer or shop and have them look at it for you.

  • Clunking Noise While Towing with Reese Puck Adapter and Demco Hijacker on a 2015 Ram 3500
  • Any clunking noise that you are hearing while using the Reese # RP30154 and Demco # DM8550034 wouldn't be alleviated by using the Demco Adapter # DM6099 instead for the puck system on your 2015 Ram 3500 unless, of course, the Reese adapter is damaged somehow. It's possible that there could be a little bit of clunking during normal use but it wouldn't be anything out of the ordinary or something that that is alarming. I recommend setting up a camera like part # RA7710 in the bed of your...

  • Trouble Finding Cold Side of Brake Light Switch on 2015 Kia Sorento
  • You may need to try to find some other wiring on your 2015 Kia Sorento until you find a wire with your tester that only gets hot when your brake pedal is pressed. I tried looking up what the wire color might be for cold side of your brake light switch but I wasn't able to find anything. If all else fails you can install the Roadmaster Universal Stop Light Switch Kit # RM-751000 for your brake controller. This mounts on your brake pedal arm and simulates the cold side of the brake light...
