Brake lights and hazard quit working

Good morning,

I attached a wiring diagram for you to view. Check the fuse for power to the switch.

Then check voltage at the switch itself. It is under the dash on the brake pedal.

For information on stop lamp circuit diagnosis, refer to Diagrams, Diagnostic Aids.

Caution: Refer to Battery Disconnect Caution in Service Precautions.

1. Disconnect the battery negative cable.
2. Disable the SIR. Refer to Disabling the SIR System.
3. Remove the pushrod retainer from the brake pedal pin. Use snap ring pliers.
4. Unsnap the stop lamp switch from the pushrod.
5. Disconnect the electrical connector from the stop lamp switch.

Installation Procedure

1. Connect the electrical connector to the stop lamp switch.
2. Snap the stop lamp switch onto the pushrod.
3. Install a new pushrod retainer on the brake pedal pin. Use an 11 mm (7/16 inch) socket in order to push a new clip onto the pin.
4. Connect the negative battery cable.
5. Enable the SIR. Refer to Enabling the SIR System in Restraint Systems.

Correct. If it works, then the switch is good.

This means either the turn signal switch is bad or the wiring to the bulbs is an issue.

4. Pop the wire harness assembly (4) into the wire harness strap (5). Install the wire harness strap (2) into the steering column support assembly (1). Install the wire harness straps (3) onto the wire harness assembly (4).
5. Install the upper and lower shrouds. Refer to Steering Column Trim Covers - Assemble Off Vehicle (Column Shift). See: Steering Column > Removal and Replacement

That would be from the switch itself.

Replace the switch.

The turn signal switch.

Okay, I attached a diagram for you to view. Check for power out of the multifunction switch with the brake pedal depressed with a voltmeter.

Roy

Let me know if there is power on those wires with the pedal depressed.

Roy

You are welcome.

Always glad to help.

Roy

If they go to the rear brake lights, yes. Check the colors and match them to the diagram.

Roy

Yellow and dark green are the ones going to the rear lights. Check the diagram I sent you to verify.

Roy

Do a continuity check to the rear lights from those wires to be sure that they are the wires.
