I have 1987 toyota 4runner model
and I keep servicing and when needed repair it on my own. worth it !!!

Drill them out then renew the number plate with rivits

IS THE SOCKET GOOD (ANY CRUD BUILD UP IN THE SOCKET) CHECK THE WIRES TO THE SOCKET FOR GOOD CONNECTIONS.

What is the condition of the bulb socket? Contacts show signs of corrosion or overheating? Use a meter to find out if it's missing the 12 volts to the bulb or if the ground is missing (open/high resistance). With the fog lamps powered on, connect the black meter lead to a good solid ground on the body of the car. Touch the red meter lead to each contact in the socket which the bulb plugs into. One of the contacts should measure about 12 volts. If no 12 volts then you will need to check fuses and wiring to find the open circuit causing the no voltage situation. If you measure 12 volts, then you know you have power to the bulb. The problem will then be with the ground. Turn off the fog lamps, set the meter to measure resistance (ohms). Leave the black meter lead connected where it was. Connect the red meter lead to the contact in the bulb socket that you did NOT measure the 12 volts at. The meter should read no/low/minimal resistance. If you measure high resistance, then you will need to locate the corrosion or open/broken wire between the bulb connector and grounding point on the car. Good luck!

Get your meter out and find out which wire gets voltage when the high beams are on.
Much easier than trying to find schematics.

welll...look at your owner's manual and you will find the answer!

you need another wireing harness go to circuit city or radio shack or best buy tell them what your doing they will sell you what you need

you may have damaged the ABS sensor or wire to the sensor up front check the wire that runs from the inner finder well and make sure it connected to the ABS sensor on the spindle

If your Santa Fe has a V6 engine 2.7L , it sounds like you have an ignition break down happening. You will need to renew all the ignition wires and check the two coils also for arcing .
