Convenience Lights Malfunction, '93 500SL

While looking for a hot wire point for accessory connection, accidently shorted driver's footwell convenience light wires (located above brake pedal in underdash cover). No fuses in main or trunk panels blown. However, both drivers door and footwell lights do not work now. Also, driver seat controls now only work with ignition on and overhead convenience lights (two located above rearview mirror) only work when switched manually (not when door opened). Passenger side ok. Where should I look for problem?
