Neither of my door side marker lights are working? Replaced the bulbs and still nothing. Is there a ground some where? All other lights are fine except the puddle lights under the mirrors. Both of those are out as well. Not sure if they are related some how? As well I can't get the cover off of either puddle light or the license plate lights. I want to replace them with LEDS. They seem stuck and I'm afraid ill break the plastic cover. Thanks for any help.
