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...
The problem lies with your adapter. There are two accepted ways of wiring a 6 way connector. One way uses the center pin as the 12 volt power lead, the other uses the center pin as the brake lead. It sounds as if you need an adapter that is wired the same way as your trailer. The Universal 7 way to 6 way adapter, part # 37549 has the center pin set up as the hot lead but can easily be changed to work with trailers that have the center pin wired as the brake. This should fix the problem. view full answer...
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... view full answer...
This is the first time I have heard of this issue on the P2, # 90885. Usually when a brake controller is making a pulsing click of some sort it indicates a possible short or even feedback from the trailer.
To see if it was the trailer or the brake controller you would have to simulate a load on the brake output circuit on the trailer connector and then drive around and see if it happens again. If it does then it is likely the brake controller. If it doesn't then trying with another trailer... view full answer...
The first step I suggest for troubleshooting your truck's trailer brake controller is to disconnect the truck and trailer and clean the connectors. If that does not correct the problem, test using a circuit tester like # PTW2992. See the linked video for an illustration of using the tester. Apply the grounded tester to the pin on your 7-Way located at the 5-o-clock position - please refer to the linked photo for guidance. Have a helper press the manual override button on your brake controller... view full answer...
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... view full answer...
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... view full answer...
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.... view full answer...
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... view full answer...
Yes we have heard of that before. Since a hydraulic actuator activates your trailer brakes by compression when you are going downhill the weight of the trailer is already putting pressure on that compression. Then when you hit a bump it is jolting your 2004 Chevy Avalanche and trailer enough that the actuator is activated and causes the brakes on your trailer to lock up. The only way to keep this from happening is to keep the actuating coupler on your trailer "stretched out". This means... view full answer...
I assume you mean that when you hit the manual override button on your brake controller, the running lights on the vehicle/trailer illuminate. If that is the case then odds are you have a short between the brake output wire (usually blue) and running light (usually brown). You will need to trace these wires back from the brake controller to the tail light assemblies on the trailer. If you have access to a different tow vehicle or trailer and you can determine which side the issue is on.... view full answer...
There are a couple of connections you may need to make under the hood to finalize the brake controller # 5504 installation. Under the hood on the driver side, remove the power distribution box lid. Once removed, you will see a ring terminal directly to the right of the power distribution box (between the box and driver side of the truck). There may be some tape holding it in place. Just cut the tape to release the ring terminal.
Next, route the wire to the front of the power distribution... view full answer...
It sounds like the problem is on the trailer side of the wiring. The 7-way on the trailer may be wired wrong or has a short so that the 12 volt power circuit is shorting to the brake output circuit and locking up the trailer brakes.
What you can do is use a jumper wire from the positive side of a 12 car battery to put voltage on all of the circuits of your trailer 7-way and then check out the 7-way diagram I attached to see what circuits should be activating.

Trailer brake controllers and trailer emergency breakaway systems like the Hopkins Engager # 20099 do wire together. You can refer to the two linked articles on installing and testing breakaway systems for help confirming your installation is correct and that the system is operating correctly.
What can happen is that corrosion can develop inside the trailer's plug or vehicle's socket and this corrosion can cause shorts and other issues that can easily interfere with normal brake controller... view full answer...
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.... view full answer...
You should not be able to feel any difference on your vehicle's braking when a brake controller is installed. This would indicate to me that there is a problem in the wiring of the brake controller. Most likely on the stoplight wire of the controller (red).
Since you said you hardwired the install I would first verify that you have the correct circuit for the red wire of the controller. It needs to be wired to a circuit that only sees voltage when the brakes are applied and none when released.... view full answer...
Since you have determined it is not an issue on the trailer side the most likely problem is bad ground on your 2002 Avalanche; you'll want to make sure your ground is securely attached to a bare metal surface free of any paint, dirt or corrosion of any kind. If ground area is already clean, disconnect the ground wire and attach it to a long piece of wire. Then run this wire to the vehicle's negative battery terminal for testing, and if this solves the issue, the ground wire can be permanently... view full answer...
The Hopkins 7-Way Blade to 7-Way Round Adapter, # 47595, was designed to be rewired. This adapter was designed to be rewired because there is no industry standard when it comes to wiring a 7-way round style trailer connector.
If your tail lights come on when the vehicle is put in reverse, then, at the back of the 7-way round end, switch the yellow wire with the green wire (see video). If that is the only issue you have come across, then that should fix your problem. If you are having... view full answer...
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...
Thank you for your purchase of the Tekonsha Primus IQ trailer brake controller # TK90160.
The error code P.L. indicates a power loss on the 12V circuit that feeds operating power from the vehicle battery to the controller. This power is carried on the controller's black wire.
You can check your installation for a loose connection at the back of the controller where the power wire from your 2010 Chevy Avalanche splices to it. You can also check for a loose fuse in the power distribution... view full answer...
