While washing our XC60 yesterday, I noticed that the passenger, signal lamp that sits in the side-view mirror was loose. I managed to slide it off and noticed it was broken off and was previously glued back on. We purchased our XC60 new, was never in an accident nor was ever loaned out to anyone. So basically, it's only been to the dealer a few times during maintenance intervals. So obviously, I'm wondering when had this happened but not to dwell on that, how do I replace it? Can I purchase the lamp assembly alone? Does it just slide back on? Any help is much appreciated. Thanks in advance!
