I doubt this is Garner Holt's fault, but rather a problem with WDW's own maintenance team, or rather the people in charge that have neglected to order them to fix it. Animatronics tend to break when they're not maintained properly, even brand new ones. It doesn't matter who made the figure if there's not an effort to perform proper maintenance on it. These tend to be temperamental show elements regardless of who made them. The trick to dealing with problems like this is to fix them as soon as they break. Not allow them to remain in this unacceptable state for weeks, months, or forever.
As said many times on these forums, there was a time not too long ago that having broken show elements like this (let alone for such a prolonged period of time) was something that the Disney company itself considered unacceptable. If a show element was broken (even small ones), it was fixed almost immediately. They used to pride themselves on their incredible maintenance policies, a standard they set for themselves but no longer abide by at WDW (apparently this standard is still at least somewhat alive at other Disney resorts, I hear at both California and especially Tokyo).
And that is apparently the problem. The wardrobe I hear has been this way for quite some time and they don't seem to have done anything to try to correct it... One hopes with a new president at WDW maintenance will start improving but the longer this remains this way, the bleaker things will look. Unlike Splash Mountain, I wouldn't see why they'd have to close the entire attraction for a long time to fix the wardrobe. I'm betting the issue could be corrected overnight.
