Foggy instrument cluster lens

The rallye lenses are held in the bezel with melted plastic pins and have more pices attached too. Lots more labor in those.
With a very small tip soldering iron, Apply light seperating pressure while heating directly in the center of the white plastic pins. You may need to alternate from one pin to another. I very often get a tiny white donut like ring of plastic that I could reuse If I didn't have donor ABS plastic on hand. Be sure to dress the remnants of those pins straight and round so the lens or parts seat properly be using the solder iron to re-bond.
