I just got home and as usual , since i park on the street, I folded my mirror. The only difference is that when I folded it this time, I heard a pop and now the mirror housing is very loose and doesn't stay locked opened or closed. Its dark here now so I can't really take things part at the moment to see whats what. Does anyone here have an idea what the problem is. Hopefully its a simple repair. Thanks in advance.
