I am having difficulty removing the dome light cover over the rear seat to replace the bulb. I can get a flat blade or narrow putty knife between the plastic cover and the roof liner material -- but it won't "pop" out. I don't want for force it to much and risk breaking the lens. Can you give me some advice?
You could try search the thread Willem provided. But the key is to pry between the clear lens and the plastic surround instead of the plastic surround and roof liner. When you are prying, trying pushing the blade towards the center of the lense but also in a downward direction. It should pop off after with that motion. The lens is held in place by tabs which are fairly short, if I remember correctly (been so long since I changed the bulb out). As for breaking the lens, it is somewhat sturdy so you could exert a bit of force.
