Ok, I just checked mine, I can get it to wiggle, but it's just the outer part, and not that much. It doesn't hit any stops like something would be loose though, just flex's. Are you sure the mirror is uhm down all the way? I know even the early ones you can tilt the whole mirror assy up for those really tight parking spots. Is it the glass or the housing that's moving? In a chiltons manual I have it has steps for the assy and the glass.
