Expert Answers about Chevrolet Avalanche
- Is the Reese POD Brake Controller Supposed to Light Up with Brakes Applied and No Trailer Attached
- I spoke with Reese about your POD controller.
When you apply the brakes with no trailer hooked up, the light will flash red briefly. It should turn off shortly.
However, if it stays on, then there may be a problem with the blue wire. Trace this wire to look for frays or corrosion. If you see any, you will need to replace it. Problems with this wire will "trick" the controller into believing that there is a trailer hooked up.
You might also test your 7-way with a circuit tester like part...

- There is one additional step that is required on your 2013 Chevrolet Avalanche that was not covered in the video with the 2012 Chevrolet Silverado. There is a red wire located just outside the engine compartment fuse box that needs to be attached to one of the front lugs inside the fuse box. You will need the M8 Nut # 185917 to complete this step. I have linked a video below for an installation we did on a similar Avalanche so you can see the additional step towards the end of the video....

- 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....

- If your Tekonsha brake controller, like the Prodigy P3 # 90195, was giving you an overload warning then that means you have a wiring issue somewhere on your 2003 Chevrolet Avalanche or your 2015 Keystone Springdale.
To find out which end it is on you will first need to get your brake controller working again try checking the fuse nearest the positive terminal in the fuse box under the hood (see attached picture) and make sure that it looks good. If it looks okay then you will want to check...

- If the fuses are good and there still isn't voltage on the left turn/stop signal then the problem lies somewhere in the wiring. I wish I knew exactly where to look, but you will have to start at the trailer connector with a circuit tester like part # PTW2993 and trace the wire back up through the vehicle trying to find where the short is a fix as necessary.
The only way you could bypass your current trailer wiring to get the correct signal would be to use a Curt Wiring Harness part # 56146KIT....

- The first thing I would do is fully activate the manual lever on the Prodigy P2 brake controller, # 90885, and release it, letting it snap back to the off position several times. This can clean the internal contacts and allow the brake controller to function properly. Sometimes dust and debris get into the controller and cause the manual contacts to remain activated, which could be the issue.
Next, unplug the connector from the back of the Prodigy P2 for 2 to 3 minutes, allowing the brake...

- This is a very strange problem. If your 2003 Chevy Avalanche has a 7-Way trailer connector, make sure that it is pinned out correctly like in the picture I have provided by checking the pins with a circuit tester, # PTW2979, if needed. Then make sure that the trailer is wired to match the Avalanche 7-Way. Anything that does not match up could be causing the problem.
If the trailer is using a 6-Way and you have an adpater that could be the problem. There are 2 ways to wire a 6-Way, the...

- If you are using the Pilot time-delay brake controller # 80550 what you are feeling with the brakes holding on after the pedal is released could indicate a malfunction inside the controller or potentially some kind of wiring issue that is letting 12V power reach the brake circuit even after the pedal is released.
If you have a circuit tester like # PTW2993 it is simple enough to test the truck side of the equation. Have a helper sit in the truck and press the brake while you have the...
view full answer... - Is Discolored Ground Pin on 7-Way Causing Trailer Light Problems
- The discolored pin on the photo you sent is the ground pin on 2013 Chevy Avalanche and that certainly could be what is causing the problem. What I recommend doing is unplugging it from your truck and using some sand paper to try and remove it.
If for some reason that does not work you can replace your socket with the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket # HM40975 which is a replacement for the factory 7-way on your '13 Avalanche.
Either way you go, I highly recommend...

- It does sound like there is a short somewhere on the brake output circuit of your vehicle. You have two options. You can try and track down the short which is going to be a headache most likely. Or you can run a separate wire from the brake controller to the 7-way so that you can bypass all of that.
If it were me I would check out the connector on your Avalanche looking for any corrosion and fixing/cleaning as necessary and if that does not fix the problem I would run a length of 10 gauge...

- I am understanding your question right you can manually put voltage on your brake output circuit but when you try to with your Hopkins Reliance the brakes do not activate? If this was any other controller I would say you most likely have other issues, but the controller you have is pretty easily damaged internally so I would say your most likely problem is an internal problem on the controller and now it doesn't put out enough amperage to activate your brakes.
For a replacement brake controller...

- There are a few potential reasons why the trailer brakes don't seem to be releasing correctly after applying them in your Chevy Avalanche.
I first recommend making sure you connected the red wire from your Draw-Tite Activator Brake Controller to the cold side of the stop light switch in the truck. This is the wire beneath the brake pedal that only receives power with the brake pedal depressed, and no power with any other function. You can use a circuit tester like # PTW2993 to confirm...

- When troubleshooting lighting issues on a trailer it helps to isolate the truck and trailer to determine where the problem is. To do this you will disconnect the trailer from your 2002 Chevy Avalanche. Then you would use a circuit tester such as # PTW2993. I have linked a video showing the testing procedure.
If there is power on the running light circuit on the Avalanche, then the issue is on the trailer. If there is not power on the running light circuit, then the issue is on the Avalanche,...
view full answer... - Can the P2 Trailer Brake Controller Lock Up the Brakes on a 2003 Chevy Avalanche
- If the P2 brake controller, # 90885, is not wired into your 2003 Chevy Avalanche correctly the most it could do is activate the brake lights. Vehicles have hydraulic brakes, not electric which is what the brake controller controls. It is possible that there is some electric ABS system that could somehow cause this issue. If it was receiving power somehow from the brake controller I suppose it is possible it could do something to the vehicle brakes.
Make sure that the brake controller wiring...

- 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...

- A factory 7-Way on an Avalanche will have the brake and turn signals for each side combined, one circuit for left brake and turn, one circuit for right brake and turn. If the truck came with a 7-Way from the factory, everything should be wired correctly there.
I would check your ground connections. Most trailer light problems are the result of bad grounds. Check to make sure the taillight assemblies have good metal to metal contact on their ground connections. Make sure the ground wire...
view full answer... - Faulty Trailer Running Light Circuit on 2004 Chevy Avalanche
- Since you have connected other trailers to the Avalanche and had the same problem, we can rule the trailer out as being the problem. (Good job, by the way.)
Use a circuit tester like part # 40376 on that brown wire when the vehicle headlights are on. This will verify that the circuit is good. If you do not get a signal, check the fuses in the power distribution box under the hood. Although the running lights on the vehicle are working, the circuit for trailer running lights is on a different...
view full answer... - Troubleshooting Brake Controller that Stopped Working after Rewiring 7-Way
- The problem you have is somewhere in the recent rewiring of your trailer connector. It sounds like there is at least one short on the wiring that is preventing the brake output circuit from functioning. Check to see if the running light circuit is possible shorting out to the brake output circuit. I attached a diagram that shows how 7-way should get wire that may be helpful as well.
I also attached a help article on brake controller troubleshooting as well.

- It sounds like there might be a loose connection on your 2008 Chevy Avalanche. The most likely culprit is a dirty or corroded trailer connector at the back of the truck. Make sure that the truck side trailer connector is clean and free of corrosion inside, where the wires attach, and outside on the pins.
You can also check to make sure that the brake controller # 80550 is connected to the correct tow package wires under the dash and to the left of the steering column. There should have...

- Since all fuses are good and your jack works with shore power, it sounds the 12v from your vehicle's 7 way trailer connector is not reaching your jack's motor. I would start by making sure your aux 12v pin on the vehicle's 7 way connector is showing 12v; use a tester like LCD Digital Circuit Tester # PTW2992. If it is not getting 12v then trace that circuit on your vehicle to check for any cracked or broken wires and also double check the fuses. If you are getting 12v on that pin then use...
