That cover is a little difficult to remove. I can wiggle it up and out usually but that is because I have done it quite a few times. You can remove the front of the wheel well to disengage the lower retainer which will help in removing the cover. Yes it does sound like it may be a ballast problem but try replacing the bulb first since the bulb and ignitor is one piece.
