2007 Chevy Suburban Cruise control and Trailer Breaks

[PSU1999]

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.

Thanks. Did you happen to have this problem? When I talked to dealership today they knew what I was talking about right away and the repair didn't seem to bad. I had trouble last season and thought it was the break controller.

You got short in pedal sensing system just like you suspect. The trailer brake controller thinks you have your foot on the brake pedal and is activating the breaks. Same thing with cruise control, system thinks you are applying brakes which disengages cruise
