Head Lamps and Tail Lights suddenly not working

Sounds like you shorted something out when the switch broke. Fisrt remove the two 10 mm bolts on the dash panel at the bottom of the drivers side. pull the lower assembly out. There are four tabs that hold the switch assembly in, two on the right and two on the left. Squezze them together to remove the switch assembly. Replace the switch assembly with a new one. Push the assembly in the opening and push the tabs out to make sure it is locked in place. If you still have a problem start checking fuses in the fuse box under the drivers seat. Also check your TBC fuses in the under the hood fuse box.
