Problem w/ flip-ups

Okay this is my situation…My flip up lights are basically messed up, when I turn on my lights the right eye lid would open but the left would stay close…I therefore open the left eye manually to get it up…here is the funny part, the will both go down when I turn the lights off or press the button, but only the right eye will flip up when turned on or the light button is pressed

Can someone help me on this
