My side rearview mirrors are acting up. The side to side movement doesn't work but when I press on the mirror it works for a bit before ceasing again. This is happening on both sides. Any suggestions or recommendations. The indy tried cleaning with compressed air but didn't work. I was thinking of spraying silicone lubricant however don't want to take a chance and damage something in there. Appreciate any experiences/opinions.

Thanks
