  • For vehicles with auto-leveling suspension the proper setup procedure for weight distribution is to put the full tongue weight on the trailer hitch to activate the vehicle's auto-level function and then from there go through the setup procedure for the weight distribution system.

  • 2011 Escalade ESV Electric Trailer Brake Controller Installation Troubleshooting
  • On your 2011 Cadillac Escalade, the wiring present under the dash is most likely not connected correctly on your Prodigy P3 brake controller # 90195. There is a good chance that the red wire that connects to your brake light switch is getting the constant power signal. It should only receive power when the brake pedal is depressed. Use a circuit tester like # PTW2993 to test this connection. I've attached a video and an article to assist.

  • Troubleshooting Prodigy Brake Controller that Flashes SH Code
  • The error code you are reading indicates that there is a short circuit somewhere in the brake outupt circut on your trailer. Most likely, there is a pinched wire or at some point the wire insulation has cracked or been worn to the point where the copper wire is contacting the trailer frame or some other metal part. Start at the trailer connector, making sure that it's not corroded or damaged, then work your way back to the brake magnets, examining the wire as you go. The controller can...

  • Troubleshooting B&W Companion 5th Wheel Hitch Not Releasing
  • The B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter - Dual Jaw - 20,000 lbs # BWRVK3500 has a binding issue with your king pin. The cam action latching handle sounds like it isn't functioning correctly. If the head has been damaged, I recommend replacing it. If it isn't damaged and yet isn't functioning correctly, I recommend contacting the manufacturer about coverage under the limited lifetime warranty. If you need to replace the head unit, the Replacement Head Assembly...

  • No Power to Brake Controller After Install
  • It appears that you have done a very thorough check of the issue to get your Tekonsha Prodigy P3 Trailer Brake Controller # 90195 powered on without the trailer being connected. I am happy to help you get your brake controller powered on. I have a help article attached called Installing an Electric Brake Controller on 2007-2013 GM Full-Size Truck or 2007-Present GM SUV. Because GM quit offering the plug in type connectors on the aforementioned vehicles with a factory tow package, there...

  • Switch on Electric Trailer Jack Just Makes a Clicking Sound
  • Since you mention that the trailer jack worked fine last year before removing it, I recommend that you start by checking the ground wire and make sure that it is secured to a clean metal surface on the trailer. Next I would make sure that your battery is fully charged and has enough amperage to run the motor. If your trailer jack still isn't functioning properly, you could have a bad switch or motor. In order to determine which component is defective, you would need to remove the switch...

  • Constant Power on Blue and Red Trailer Brake Controller Wires on 2007 Cadillac Escalade
  • There should not be power all the time on the red wire or on the blue wire on a brake controller. You should not have to connect the red brake controller wire to the brake switch. You should be connected to the tow package wiring under the dash, to the left of the emergency brake pedal. There is a bundle of wires held together with a white tag. There should be a light blue wire here that you would use but not at the brake switch. It is also possible that if you are connected to the tow...

  • Troubleshooting No Propane Flow On Trailer with New Tank and New Regulator
  • Yes. The pigtail could be the issue. I recommend replacing the pigtail with the MB Sturgis Propane Hose w/ Back Check - Type 1 x 1/4" MPT - 20" # 100473-20-MBS. There is an internal back-check on Type 1 fittings that could be the issue.

  • Trailer Running Lights Fuse on 2010 Cadillac Escalade
  • The "Trailer Park Lamps" fuse, which looks to be located in the #25 position inside the power distribution box under the hood, is the correct fuse to check/replace on your 2010 Cadillac Escalade. Running lights are often referred to as park lamps. If for some reason replacing this fuse doesn't resolve the issue please let me know and we can do some more troubleshooting. If this is the case then there's likely something going on with the trailer wiring.

  • Troubleshooting Codes for Redarc Tow-Pro Elite Brake Controller Installed in 2018 Cadillac Escalade
  • It sounds like you have installed your Redarc Tow-Pro Elite trailer brake controller # RED44FR using the custom GM wiring adapter # 3016-S. This is the correct harness for the 2018 Cadillac Escalade with factory 7-way connector. An error code from ANY trailer brake controller most often is a result of a connectivity issue like a loose or dirty trailer plug (or vehicle socket). For the Tow-Pro Elite a flashing error code may remain until you unplug the trailer and wait at least a minute...

  • Troubleshooting Interior Dome Lights On an Enclosed Trailer Not Functioning
  • Depending on how your 2011 Noe trailer was wired you will have a couple things to check. First the exterior running lights, brake lights and turn signals will run off different circuits than any interior dome lights. Typically with interior lights there will be a dedicated battery for the lights so they can still be operated when not connected to your tow vehicle. Otherwise they will likely just be connected to the auxiliary charge line circuit on the 7-way. A Test Light # PTW2993 can be...

  • Troubleshooting Falcon All Terrain Tow Bar Arms Difficult to Slide In and Out
  • I'm not sure what process you used to clean and lubricate your # RM-522, but I would soak the arms with degreaser and then move the arms in and out while rinsing them off with water. You can also use the Roadmaster Tow Bar Cleaner # RM-9932. After they are rinsed, dry the arms thoroughly and lubricate them with a dry silicone spray like the # RM-747. Assuming this was done, you need the Repair Kit for Roadmaster Falcon and Blackhawk All Terrain Tow Bars # RM910003-85. This should fix the...

  • Battery Drain Issue When Flat-Towing 2012 Cadillac SRX Using Air Force One Supplemental Brake System
  • Ironically we just had the same issue with an SRX. The problem was that when installing the Air Force One # SM99243, one step was not done and caused the battery to go dead. When installing the unit in the SRX, the brake pedal has to be moved to the forward position closest tot he driver seat. If it is not, when the unit is installed and tries to adjust itself it applies just enough pressure to make the brake lights go on and run the battery down. It may be something not noticed with the...

  • Troubleshooting Wiring Harness On 2007 Cadillac SRX
  • Any wiring harness can go bad for a variety of reasons whether it is a bad module, crimped or broken wires, or corrosion on the pins. You can troubleshoot a wiring harness to see if there is a problem by using a circuit tester like part # PTW2993. First, you want to make surer there is no corrosion in the trailer connector, and clean it is any is found. Then have someone sit in the driver seat and run through the functions while you test the trailer connector pins for function. If any...

  • Troubleshooting 4-Way Wire Harness installation On 2009 Cadillac SRX
  • The wiring harnesses and kit, part # HM48895 and part # HM46155 you referenced in your question are not designed to be a fit for your 2009 Cadillac SRX. If you find that you have the correct wire harness for your SRX you can check the wiring to make sure all of the wires have been connected as the instructions state. Also, you will want to make sure the ground wire has been secured to a clean bare metal surface. Loose or corroded grounds can cause some of the same problems you described....

  • Add-On LED Turn Signals are Hyper Flashing on a 2007 Cadillac SRX
  • The hyper flashing might stop if you put them on all turn signal circuits, including the front ones. And it may not. Since this is a non-standard set up it will take some trial and error to determine what the problem might be. If you have the load resistors grounded to the same ground as the light I recommend moving it to its own ground location specifically to a clean and corrosion free bare metal surface with no paint or coating. If you have the resistors grounded separately already...

  • Troubleshooting Transmission Fluid And Engine Coolant Mixing On 2003 Cadillac CTS
  • Sorry to hear about the problems with your brother's 2003 Cadillac. The first thing you will want to do is have the transmission taken care of. I am not aware of a separate cooler for the transmission located under the intake manifold. Typically what is used is a line that runs from the transmission to the radiator. The radiator holds engine coolant and the transmission fluid line is run inside the radiator as well. The radiator cools both the engine coolant and the transmission fluid...

  • 2014 Cadillac Escalade Wont Start After Curt Brake Controller Installation
  • Thanks so much for the purchase from us of the Curt Discovery Trailer Brake Controller # C84VV for your 2014 Cadillac Escalade, and I'm sorry to hear of this issue you are having. This controller, which you'd use with Wiring Adapter for Curt Trailer Brake Controllers # C51515 assuming the Escalade had a factory 7-way already, should not have anything to do with the vehicle starting or not, which means there was a mistake somewhere along the way with the wiring process. I have added a link...

  • Turn and Brake Lights Do Not Work Using 6-Diode Kit and Converter for Towing a 2012 Cadillac SRX
  • It sounds like you have a good grasp on the installation of the Roadmaster 6-Diode Universal Wiring Kit, # 154-792-118158, and you have already gone through a few troubleshooting steps, so I would recommend troubleshooting the converter box from the # 118158 wiring harness. Installing the # 118158 wiring harness at the front of your 2012 Cadillac SRX instead of closer to the taillights is not a problem. To troubleshoot the converter box of this wiring harness, I would first recommend...

  • The TowReady wiring harness for the Cadillac SRX that you referenced, part # 118259, is intended for vehicles that have the factory tow package installed. Thank you for your recent purchase of a hitch and related items along with this wiring harness. The exact components that constitute a factory tow package will vary among auto makers and can also vary among different vehicle models and model years. Sometimes wiring may be put in place at the factory but may not be connected at one or...
