Ground. Get your correct schematic, perhaps from autozone website and search for where you lose what. There are many years and models with many wiring variations. Disturbing the ground, or having rust or corrosion can cause this as well as inadvertently blowing fuses in the circuits. The inline fuses by the A/c evaporator case under the hood may prove helpful as well. Sockets and their circuit boards can be an area of concern for testing power and ground to your new bulbs. Careful to get the right schematic.
