In my 2002 the bulb that lights up the power windows/mirror/lock buttons on the door panel has broken a fillament. How do I repace that? Do the wires seperate from the plastic bulb assembly (saw little metal tabs that the clip braces in there) or is it going to be a bigger pain in the *** then that? And also had to replace my turn signal bulbs because water had gotten in there and corroded the bulb end and crackled the orange coloring on the bulb. I put some coolant liquid gasket around the existing rubber gasket but do you guys think this will work or is there a better way to seal the blinker assembly up? Thanks in advance.
