• Left Side Trailer Running Lights Not Working, All Other Lights Work Fine
• This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare...

• Excessive Noise When Using Curt A16 Fifth Wheel Hitch On 2015 Chevrolet Silverado 2500
• There is not an actual adjustment that can be made on the A16, part # C16621. The hitch has a pivoting head that is cushioned so a bit of movement may be present when towing. If you can find the source of the noise it can help. It may be caused by the slider or by the jaws on the king pin, or the large pin that is in the middle of the hitch. You may want to check out the Curt Fifth Wheel Rail Sound Dampeners, part # 16900. These are neoprene pads that fit between the hitch and the rails...

• No 12 Volt Power at Trailer Connector On Rear of a 2002 Chevrolet Silverado
• You will need to take the cover off of the fuse panel under the hood and check to see if there is a wire connected to the farthest forward positive post and if there is a 40-amp fuse installed in the nearest fuse location (see photo link). This fuse is one of the larger styles of two blade fuses. If the wire is connected and the fuse is missing or blown then installing a new fuse in this location will solve your problem. If the wire is not connected to the post, then you will need to find...

• Trouble With Rusted Weld Nuts on etrailer Hitch e98865
• It can take a pretty significant cleaning process to completely clean out the weld nuts for installation on a hitch like the Draw-Tite # 76028. You can use a wire brush like # 814092 like you did but if it wasn't enough you'll need to take an extra step. As you can see from the cut out I added of the linked help article, what you'll want to do is, while the hole is still lubricated, use a ratcheting wrench and run the bolt in and out slowly, which should loosen the corrosion and allow...

• Trailer Running Lights Not Working when Connected to a 2002 Chevy S-10
• You can determine if the issue is on your 2002 Chevy S-10 by checking its trailer connector with a circuit tester such as # PTW2993. Have someone sit in the truck and turn on the running lights while you test the pins on the connector. If you are not getting any power on the running light pin then that does indicate a problem on the truck side. If the trailer connector on the truck is factory installed then it could be a fuse. Use the truck owner's manual to find the fuse locations. Be...

• Troubleshooting Tekonsha Prodigy Brake Controller Installation in 2003 Chevrolet Silverado
• The Prodigy P2 brake controller # 90885 is available on its own without the matching wiring harness # 3015-P that joins it to your under-dash connector. Based on what is happening I think you may have a wiring issue in the trailer and/or vehicle connectors. Corrosion can build up inside or on the electrical contacts in a vehicle socket or trailer plug and that corrosion can cause different circuits to become bridged together. For example, if the 12V auxiliary power circuit was bridged...

• Hopkins Smart Hitch Backup Camera and Aligner Will Not Show Reverse or Everyday Mode
• I reached out to the manufacturer, Hopkins, to see what you could do in order to try and find the issue with your back-up camera. What they said was: "If they are losing the modes or if the gridlines are disappearing that means the circuit board in the camera plate is going out." They said that due to that you will need to replace your Hopkins SmartHitch Backup Camera and Hitch Aligner System # HM50002.

• Loosen Lippert Slide Topper Tension
• I reached out to my contact at Lippert to verify the procedure for loosening the tension on your slide topper awning. I have attached a link to the installation guide. On page 6 and step 11 is a description of releasing the awning tension. I have also included a link to a video of the install instructions produced by Lippert. Keep in mind that there is a torsion spring inside of the roll up tube and much like an oldfashioned pull down household shade - if you let go it will whiz around...

• Service Auxiliary Trailer Brake Light Stays Illuminated After Installing Tekonsha Prodigy P3 # 90195
• Since your Tekonsha Prodigy P3 # 90195 is working and correctly activating your trailer brakes, you need to take your vehicle in to a dealer to be flashed. This issue can occur when disconnecting an integrated controller and installing an aftermarket controller. Basically, the computer on the truck thinks there is an issue with the controller because the factory controller has been removed. A dealer can flash the onboard computer to resolve this problem.

• Trailer Lights Stop Working When Headlights are Turned On with a 2007 Chevrolet Avalanche
• The most likely cause of your problem is a bad ground connection. It has enough of a connection that it works in the day time because you have less current draw on those circuits with the head lights off. As soon as the headlights are on, you are pulling more current than the weak ground can support. Check the ground connections on the trailer wiring. Make sure you have good metal to metal contact. Paint and corrosion can act as insulators so make sure the grounds are touching clean metal....

• Tow Package Fuse Locations on a 2006 Chevy Silverado
• From what I was able to find there are several fuses associated with the tow package wiring on a 2006 Chevy Silverado. In the instrument panel on the side of the dash you should see RT TRLR ST/TRN for trailer right turn and brake signal and LT TRLR ST/TRN for trailer left turn and brake lights. In the center panel in the truck cab there is only one fuse and it is for brake controller power. Under the hood there is a fuse that goes with stud # 2 for accessory power/trailer brakes, one...

• No 12V Power or Running Lights on 7-Way Trailer Connector on 2004 Chevrolet Avalanche
• If the 7-way trailer connector on your 2004 Chevrolet Avalanche is part of a factory-installed tow package (if it is it should have a GM logo on it), then all wiring and fuses should be in place as part of the tow package. As you noted it is still possible that there may be fuses missing from the accessory fuse block in the engine compartment, or there may be blown fuses. It could also be that the wire lead for the 12V+ circuit is not connected at the fuse block. Please note that trailer...

• Trailer Brakes are Randomly Engaging
• It sounds as if you might be using the wrong brake control wiring adapter. Unplug the harness from the connector under the dash, and examine how it is pinned out, comparing it to the photos I have edited for you. In the 2007 Classic Silverado model, the red wire should be pinned in the D location as shown in the photo. If the wire is in the wrong location, you can remove the blue clip from the connector, and use a small screwdriver to unclip and free the red wire and move it to the correct...

• How To Activate Furrion Vision S Side Camera Views With The Turn Signal
• Since you're powering the Furrion Vision S RV Camera System # FCE48TASL-05 off of the trailer battery instead of the tow vehicle it wouldn't be a PWM wiring issue like you're suspecting. Where exactly do you have the trigger wire ran to? If it's not running to the junction box on your trailer and tying into the turn signal circuit then you're just getting the running light circuit power and not getting anything for the cameras to trigger on. If that's all good then the next step is to...

• Draw-Tite Brake Controller Part # 5504 Not Lighting Up After Wiring To 2010 Chevrolet Tahoe
• It sounds like the connections of your # 5504 that need to be made under the hood of the vehicle have not been made. There are two wires, both Red/Black with eyelets on the end. One wire is located between the fuse box and the driver side fender, the other wire is located under the brake master cylinder. Each wire has a different sized eyelet on the them and will connect to the studs at the front of the fuse box. You will need an M6 nut, part # 185916 and an M8 nut, part # 185917, to attach...

• Troubleshooting Stop/Turn Signals Not Functioning on a 2013 Chevy Impala with Tow Ready Harness
• Most likely the problem is the grounds of your trailer wiring since the stoplight/blinker circuits require more amperage and that's typically where an insufficient ground problem shows up. Here's how you will test everything though: First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If the voltage checks...

• Troubleshooting Wiring Harness on 2003 Chevy S-10
• It is likely the result of a bad ground, but in order to determine the specific problem you encountered after installing harness # 118359 you'll need to use a circuit tester such as # PTW2993 to test the connector on your S-10 after disconnecting it from your trailer. Check the wiring going into your harness from your taillights to see if those wires are carrying the correct signals, if not then the issue is with the vehicle wiring. If the signals going to your harness are okay, you'll...

• Why Does 4-way Connector Harness On 2003 Chevrolet Express Van Have Red Wire Grounded?
• Based on the picture you provided it looks like the harness you have was designed for either a 2-wire (combined brake and turn signals) or 3-wire (separate brake and turn signals). Since your 2003 Chevrolet Express Van 3500 has combined wiring you would need to ground the red wire, which is what they have done. You didn't mention what exact issue you are having regarding the taillights on your 2018 Coleman trailer, but I would start with using a circuit tester like # PTW2993 to test each...
