I did a repair today on a fairly new house trailer and found a cut wire. What really surprised me was how it was wired. They used self-contained switches that had push-on knife blade type connections (like some of the phone jacks) with no box needed. The romex was run into the switches which were closed up. They customer also complained the lights would dim when the A/C would start, poor connections probably part of the problem.
Hard to believe these devices meet code, I'll have to check on it.
