2007 Chevy Suburban Cruise control and Trailer Breaks

2007 Suburban towing a 2005 Starcraft Aruba. I read online that this vehicle is prone to a switch in the break pedal shorting out and cuasing the cruise to not work and I am having this problem. My question is would this affect the trailer breaks? When I connected this spring as soon as I plug in to the tow vehicle the break controler automatically goes up to 50 and the the trailer breaks are engaged and stay on. They do release if I unplug so they aren't rusted but could the break padal switch in the truck cause this? I figured I would rule that out first before starting to try to diagnose the trailer. I did have sporadic break issues last season but the cruise was working on and off then too which is what got me to wondering.
