Dqs tow mirrors issue

[bmws1k]

Hi I recently installed dqs tow mirrors everything works but sometimes when I fold them in or out sometimes the left moves about a inch or so then stops re press the fold button then they are fine. Don’t hear any grinding could there be stuff inside like salt ? I live in Canada. This doesn’t happen all the time which is driving me crazy. And it’s not just the left side it happens to both maybe hopping someone on here has ran into this issue

Thanks
