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...
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... view full answer...
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 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...
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...
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... view full answer...
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...
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...
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...
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...
On your 2013 Chevy Avalanche, I recommend you test the signals at your vehicle side trailer connection when a trailer is not connected using a circuit tester like # PTW2993. It sounds like you have a short in that right turn signal wire or a bad ground to your vehicle. You will want to check the ground connection first to make sure it is bare metal to metal without corrosion or debris. You can use the circuit tester to make sure your wiring is working correctly between your connection... view full answer...
The brake controller wiring on a 2013 Chevy Avalanche is a bundle of 5 wires located under the dash between the brake and the emergency brake pedals. The wiring harness will have a white label wrapped around it, which should make it easier to locate. A plug in harness like the # 3016-P isn't needed on your Avalanche.
Your brake controller will wire directly to the bare ended wires in this harness, the wire colors will match up as follows:
Red/Black tow package wire connects to Black controller... 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...
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...
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 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... view full answer...
There are a few connnections under the hood of your 2003 Chevy Avalanche that need to be made for a brake controller to install and power on. If you check out the help article I attached you'll see what those connections are. 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...
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.

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... view full answer...
