P2 Brake Controller

Hmm guess i need to get comfortable adjusting the brake controller then. I understand the principles behind setting it, i just need to hook up my trailer and actually do it myself a few times to get the feel for it. Thanks guys

Before you start checking contacts in the hitch connector and use a volt meter on the magnets why not drive it a half hour and use the brakes some to see if rust is the issue. That would be my first effort at a resolution especially since it worked just right before it was put away for the winter.
