Expert Answers about Buick Envision

• Troubleshooting Supplemental Braking Issues On A 2017 Buick Envision
• The Brake Buddy Classic 3 Portable Supplemental Braking System # HM39494 activates off of inertia so the e-assisted brakes on your motorhome will actually help the Brake Buddy work less hard. If the breakaway pin was removed or you're having issues with the line that communicates to the breakaway that would cause the Brake Buddy to depress the brake pedal. You could also have an issue where you could be braking and the Brake Buddy is doing its job depressing the brake pedal and then intermittently...

• Troubleshooting Brake Light Failures When Flat Towing A 2019 Buick Envision
• The Roadmaster Even Brake Portable Supplemental Braking System # RM-9400 wouldn't affect your brake lights in that manner. You most likely have a short or loose connection in the tow bar wiring which is causing the turn signal to work but not the brake light. You'll need to check all of the wiring running from the tail lights to the 4 or 6 wire port you have on the front of your 2019 Buick Envision for any shorts, kinks, or brakes in the wires or a complete disconnection of any wires.

• Troubleshooting Right Brake Light Coming On when Left Blinker Activated on Flat Towed Vehicle
• I would start by checking your ground wire on the motorhome and on the vehicle side of the Roadmaster # RM-15267, since that's the root of a lot of issues we see and should at least resolve the issue with the license plate light, but there's a lot going on here. I will also say that the diodes are not wire specific, meaning they can be used on any wire. To have the right brake light come on when the left blinker comes on is rather odd, since they should be on completely different circuits....

• Is It Normal To Hear A Clicking Noise Coming From A 2-Wire To 3-Wire Converter Box
• While it's not unusual to hear some clicking from the relays inside of the Vehicle to Vehicle Tail Light Converter # 118158 it can be an indicator that you may have a short in your wiring. I recommend checking the wiring for any damage or loose connections as well as checking to ensure that you have a good ground. You'll also want to test your light functions to ensure that the converter box is properly operating as well.

• Troubleshooting RoadMaster NightHawk Tow Bar Arms That Won't Lock Into Place
• Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights # RM-676 has a self aligning design which means that once you hook up the to bar to your vehicle and your RV and drive forward the arms will extend and lock into place automatically. If it is not automatically locking into place then you most likely just need to lube it. You have to use a silicone spray to lube your tow bar as other lubes like WD-40 will cause the internal bearings to swell or will collect dirt/debris that...

• Troubleshooting Invisi Brake From Roadmaster Where Compressor Does Not Come On
• In the installation instructions for the Roadmaster BrakeMaster # RM-8700 there are two fuses wired to the air compressor circuit. One 20 amp fuse on the power wire of the battery, and a 10 amp fuse connected on the blue wire that runs from the ignition switch to the air compressor. Inspect these fuses and any poor or loose wiring connections. Try using a jumper wire 12-volt source to connect to the compressor to see if it operates. If the compressor works, then the issue is along the...
