So, the passenger-side mirror on our 240 is wobbly. I tightened the Phillips-head screw in the manual lever area inside the window, but the whole mirror housing is a bit wobbly still, about 3-4 mm of play.

It appears that there is a rubber plug on the outside bottom of the mirror, right next to the hinge, and I'm guessing that I were to manage to pry that out, there would be some kind of screw inside to tighten. But before I take that step, I'd like to hear it from the experts.

Your help will be appreciated for this 37 year old treasure!

 

my experience in general with mirrors on 25-30 year old cars is, the adjustment mechanism get funky and break. this isn't volvo specific, I've had issues with ford trucks, with mercedes, you name it.
