Expert Answers about Chevrolet Silverado Classic

• Troubleshooting Hopkins Smart Hitch #50002 with No Power to Monitor
• Since there is no power to the monitor on your Hopkins Smart Hitch # HM50002, you will want to check the reverse light function on your trailer connector using a circuit tester like # PTW2993. The reverse light pin location is the center pin of your connector. If you don't have this function, check your owners manual for fuses first and then check connection for bent pins and proper ground connection. Finally trace that reverse light wire to find a short probing the wire every couple...

• Trailer Brakes Will Not Lock Up with Primus IQ Brake Controller # TK90160 in 2007 Silverado 1500
• The fact that your trailer brakes will not lock up at 20-25 mph speed does not necessarily indicate a problem with the brake controller. The best way to isolate the problem is to apply a circuit tester to the wires leading into one of the trailer electric brake assemblies to read the voltage reaching the brake. You can use a voltage tester like # PT89ZR to read the voltage being delivered to the brake assembly. You should read +12 volts or very close to it at each brake when the controller...

• Troubleshooting Trailer Brake Controller Brake Power at 7-Way Without Trailer Connected
• When you don't have a trailer hooked up to your 2007 Silverado, the 5 o'clock pin where the brake controller output is, should not have any power until you put a draw on that wire with your test light like circuit tester # PTW2993. As soon as a draw is placed on that pin, there should be a dim light that should increase in intensity as you hit the manual override slide on your controller. A proportional brake controller will not show braking because you are not moving except with the...

• Troubleshooting Trailer Running Lights with 2007 Silverado 1500
• The lid of your Silverado's power distribution box should have a legend indicating the function for each of the fuse positions. Check that for a 15-amp fuse labeled TLR PARK that should be in a fuse location near the outside edge of the power box. Check that it is not blown and that there is not just a dummy fuse in that position. If the fuse is good then check that the main ground wire for both the truck's and the trailer's wiring harnesses is secured to a clean bare metal surface that...

• Malfunctioning Right Turn and Brake Lights with Factory Installed 4-Way Trailer Connector
• Since you have a factory 4-Way and 7-Way, they will be wired to the same harness on the vehicle. The extra 3 wires for the 7-Way go directly to the plug but the 4 shared light wires should be split. We need to determine if the problem is between the 4-Way and the harness connector or if it is further up the harness in the vehicle wiring. Open the cap for the larger round 7-Way at the rear of the vehicle. As you look into it, the blade pin in the 3:00 position would be for right turn and...

• No Accessory Power At 7-Way Connector On A 2007 Chevrolet Silverado Classic
• I would check the power distribution box under the hood of your 2007 Chevy Silverado Classic. The box is located on the inside of the drivers side fender. Remove the cover, and locate the two auxiliary power posts on the inboard side of the box. If you have the factory 7-way on your vehicle, the power posts should have wires connected to them that will give you power for the brake controller and power for the 7-way connector at the rear of your vehicle. These power posts will also have...

• No Trailer Brakes with Brake Pedal Pressed on a 2007 Chevy Silverado Classic
• On a brake controller the red wire is associated with the brake pedal. Use a circuit tester such as # PTW2993 to test the red wire. It should show power when you step on the brake pedal. If it does not have power then you could have a blown stop light or CHMSL fuse. It could also be that the red wire is not in the correct position for your 2007 Chevy Silverado Classic. Then end that plugs into the truck should look like the picture I have included. If the red wire is in a different position...

• Buzzing Sound Behind Wheel of Trailer When Brake Controller Connected on 2007 Chevrolet Silverado
• I spoke with my contact at Tekonsha and it sounds like you may have the wrong plug-in wiring adapter. To install the Tekonsha Primus IQ Trailer Brake Controller, # TK90160, in your 2007 Chevrolet Silverado Classic you will want to use wiring adapter, # 3015-P. To determine if you have the correct harness you will want to follow these steps. Connect the trailer to your Silverado and the controller should display a "C." Next turn on the headlights and check to see if the "C" changes to numbers....

• Red Wire for Brake Controller Signal Lost with New Trailer for a 2007 Chevy Silverado Classic
• I took a look at the online version of the owner's manual for your 2007 Chevy Silverado Classic and on page 599 you can see the location of the Vehicle and Trailer HighMounted Stoplamp (VEH CHMSL) fuse. It sounds like this is what went out and I recommend checking it to make sure it is still in good working order. If you can't tell the status of the fuse simply replace it with a fuse that you know is working correctly and see if that makes a difference. Let me know if it doesn't and I...

• Troubleshooting P3 Brake Controller Not Able to Lock Trailer Brakes
• That's an odd problem to have with what we know as the very reliable Prodigy P3 # 90195 brake controller. Do you have the gain turned all the way up and are sliding the manual override all the way when testing it? Is the controller level from side to side and facing the rear of the vehicle squarely? Typically the only time we'll see issues with the P3 not activating properly is when it's not mounted properly.

• Brake Pedal of 2007 Chevrolet Silverado Classic Doesnt Activate Trailer Brake Controller
• There is a usual suspect here. Have a helper step on the brake pedal while you stand at the rear of the truck. Is the third brake lamp working? The Silverado gets its brake signal for the tow package from the third stop lamp circuit. Open the driver's side front door and remove the fuse panel cover on the side of the dash facing the door. Look for the VEH CHMSL fuse (center high mounted stoplamp). If the fuse is blown, replace it and you should be good to go. Here's something you might...

• Troubleshooting SurePull Digitrac Brake Controller
• Unfortunately I can't look up the manual for your unit as it is a part we don't carry to see what that error message is. I can tell you the C you were seeing before in most cases simply meant the trailer was connected. The symptoms you are describing with not enough and then too much brake makes me think that you either have a short in your brake output wire (normally blue wire) to your trailer connection or the unit itself is failing. You can use a circuit tester like # PTW2993 to test...

• Why am I Not Getting Power on My 7-Pin Connector for My Tekonsha Prodigy?
• If you are getting the "NC" error message on your Tekonsha Prodigy P2 Trailer Brake Controller - 1 to 4 Axles - Proportional # 90885, this could mean a few things given that you are not getting power on the ground and brake. I went ahead and attached the error code description from the instructional manual. Since you are not getting any power, I recommend checking all connections of the 7-way harness to make sure there are not any shorts anywhere along the wires. Another thing to check...

• Troubleshooting No Green Light on Tekonsha Voyager Brake Controller
• According to the troubleshooting guide for the Tekonsha Voyager Trailer Brake Controller # 39510 when there is no green light with the trailer connected then that means you either have corrosion on the trailer plug contact or you have a loss of power or ground connection. Check the 7-Way connector both on your tow vehicle as well as your trailer being sure to clean any debris or corrosion that you find. Once that is done check to make sure that all of your ground connections on your trailer...

• Troubleshooting Curt Brake Control Harness # C51352 Installation in 2007 Chevrolet Silverado Classic
• The Curt Brake Control Harness you reference, part # C51352, is compatible with both time-delayed and proportional brake controllers from Curt and is intended for vehicles with factory tow package wiring. As you noted, the connection port for the vehicle-side connector is under the dash in the electric junction box.

• Troubleshooting Tekonsha Prodigy P2 Brake Controller Staying Lit and Numbers Flashing
• It does sound like your Tekonsha Prodigy P2 Brake Controller # 90885 is just in need of a manual reset. The only way to really do this though is to unplug it from power by removing the plug at the back of the controller itself or unplugging from a factory port behind the truck's dash (if it was equipped with one). If you truly aren't able to access the plug then your only option will be to sever the black 12V wire from the back of the controller to cut off power. Once you are able to...

• 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...

• 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.
