Have Ford Questions? Ask a Mechanic for Answers ASAP
What year, make and model Ford are you working on?
Thank you. What have you already checked or replaced?
Ok, first a simple check. Step on the brakes and have someone check and se if all the brake lights work.
Ok. Replace the brake light switch. The shifter interlock switch gets power from the brake light switch when the pedal is depressed. Also check the wires to the switch.
The brake light switch is mounted under the dash on the brake pedal. Below is a diagram on how to replace it.
If you need more help, please ask.
Is this an 4 door Explorer, 2 door Explorer Sport or an Explorer Sport Trac?
Yours will look like the one below.
