Window rolls up, then down half way

[texomawaves]

I fully depress the window switch and the window rolls all the way up automatically, but then it automatically rolls down half way. I can override this by depressing the window switch lightly and manually creep the window up to close position. I sometimes hear a click noise when the window rolls all the way up. This must be some sort of protection feature that prevents kids fingers from getting smashed. I suspect a switch may be flakey or some kind of interference. Any recommendations where to start looking? thanks.
