Expert Answers about Chevrolet TrailBlazer
- Troubleshooting Time Delayed Brake Controller With Dim Display
- There is really no way to make the Curt Discovery brighter. Best advice I can give you is to shade it with your hand or you could make some kind of shade/hood out of black construction paper or other material and tape it on if you want to go that far with it. Outside of that, the only thing I could recommend is replacing it with a different brake controller.
One way or another I would say you're better off with a proportional brake controller which will give you a better, safer towing...

- It sounds like your Prodigy P3 # 90195 installation in your Trailblazer went perfectly and your Dodge Van had issues. The issue could be a couple of things, but I recommend checking your 7-pins at your trailer connector for function using a circuit tester like # PTW2993. If everything works properly there, then the issue is most likely a ground connection on your trailer. Sometimes the ground will work fine with one vehicle but not another. Make sure the connection is bare metal to...

- I spoke to my contact at Reese about the Replacement Head for Reese Weight Distribution System part # RP58112 and they informed me that the misshapen holes are more than likely a result of poor lubrication. The holes in the head for the spring bar sockets need to be lubed with some spray white lithium grease before each use. When the sockets in the spring bar head are not lubed properly, they create excess heat which can cause the holes to become oblong after extended use. The tension on...
view full answer... - Troubleshooting Trailer Wiring that Stopped Working with Tow Vehicle Right Blinker
- This to me sounds like a weak ground or a short to ground on the trailer's right side taillight assembly. I'd go over the wiring of the trailer looking for any obvious signs of a short like cut or exposed wire and fix as needed.
For more info check out the help article I attached that covers troubleshooting trailer wiring as well.

- The adapter that you purchased may be wired or configured differently than your trailer. You will want to plug in the adapter and test the pins on it for function. A traditional 5-Way flat will have the far left pin as electric brakes or for an electric lock out. Since your trailer has surge brakes, it probably has an electric lock out so this pin would need to be connect to the reverse light circuit on the vehicle.
The pin next to that is for right turn and brakes. The next pin is left...

- On the Valley Journey brake controller, the OC code indicates that the manual override lever is being applied and there is no trailer connected. If this is happening any other time, there are some things you can do to fix it. Start by fully applying the manual override and letting it snap back into place. Do this several times to clean the contacts inside the brake controller.
Next, with the trailer disconnected, check the trailer connector on the vehicle and clean out any dirt and corrosion....
view full answer... - Troubleshooting Interior Lights Not Working for Enclosed Trailer
- The interior lights of your enclosed trailer are likely connected to the 12V (Auxiliary) power pin on the 7-Way of your trailer. You can verify this by applying 12V power from a separate battery to this pin and seeing if that supplies power to your lights (see attached picture).
If your 2007 Chevy TrailBlazer doesn't have power on the corresponding pin (see attached photo) then that would explain why your interior lights aren't working. I took a look at the online owner's manual for your...
view full answer... - Troubleshooting Trailer Lights Blinking Out of Sequence on Trailer Towed by 2007 Chevy Trailblazer
- It could be a bad ground or a short. You will have to check the grounds on each of the trailer lights and on the trailer connector. The lights usually ground through the mounting studs. If there is any dirt, corrosion, or rust it could cause a bad connection. You will also want to check where the light bracket mounts to the trailer and the ground at the trailer coupler. I have included videos below on testing for a ground and testing for shorts.

- First, I suggest you use a circuit tester kit such as #PTW2992 to confirm the function of each vehicle wire before connecting them to the pigtail leads for the brake controller.
Find the one wire that has 12V power all the time, one that has power only when you press the brake pedal, and two that carry no voltage when tested.
Remove the quick connector plug on the brake controller # HM47295 and splice the 4 wires to the function wires under the dash. The 4 wires on the brake controller...

- On a 6-year-old vehicle, there might be a corrosion issue on the trailer connector. Can you see any green corrosion on any of the pins in the connector? If so, the corrosion might have spread to the interior of the connector preventing the signal from getting through to the pin. As a first step, use a circuit tester like part # PTW2993 and test the wire for the right directional circuit entering the 7-way connector at the rear (as the right turn indicator is activated). This will rule out...
view full answer... - Troubleshooting Using Left Blinker That Engages Both Trailer Signal Lights
- In many cases a bad ground is to blame if you are turning on your left blinker and both of the turn signals on your trailer are going, but in order to determine the specific problem you will need to use a circuit tester such as # PTW2979 to test the connector on your 2003 Chevy Trailblazer after disconnecting it from your trailer. Check the wiring going into your harness from your tail lights to see if those wires are carrying the correct signals, if not then the issue is with the vehicle...
view full answer... - Trailer Lights Work Off and On when Connected to a 2003 Chevy Trailblazer
- What you are describing is a ground issue most likely caused by a dirty or corroded trailer connector on the vehicle. Use a wire brush such as # 814113 to clean off corrosion on the pins. If you can take your vehicle side connector apart then check where the wires attach and clean/repair as needed.
You can also inspect the vehicle side wiring from the trailer connector forward on the vehicle and repair any damaged wires.

- I spoke with my contact at Tekonsha and he said you want Nothing less than 10 volts at the wheels of trailer. If you are only getting 4 volts from the controller back to the trailer connector then more than likely you have a problem with your wiring. What I would do is inspect both trailer connectors inside and out, looking for corrosion, bent pins, or exposed wire that could cause a short and fix as necessary. I attached an FAQ article on troubleshooting brake controllers for you to check...
view full answer... - Utility Trailer Brake Lights Not Working When Headlights are On, on a 2004 Chevrolet Trailblazer
- It sounds to me like you have a bad ground on the trailer. You will need to make sure the white wire from the 4-Way connector on your trailer is grounded properly and then check all of the ground connections on the trailer especially where the taillights are mounted to the trailer frame. Also, if the light brackets are bolted to the trailer check to be sure they are making good ground contact to the trailer frame. If a plastic license plate holder is mounted between the left side taillight...
view full answer... - No Output at Trailer Connector for Right Turn or Running Lights on 2002 Chevy Trailblazer
- You say that your Trailblazer has a tail light converter? The Trailblazer typically does not need a converter. If you have an aftermarket converter, you can troubleshoot the converter by using your circuit tester on the input side of the converter. Test each wire as its function is activated. If you have signal going into the box on the right directional signal wire (usually a green wire) and the tail/running light wire (usually a brown wire) but no signal on either of these wires exiting...
