2001 Explorer Sport ,Rear Driver Brake Light and Turn Sig. Broke

Stop Lamps
The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The body control module (BCM) provides a 5-volt reference voltage and low reference to the brake pedal position sensor. The position sensor provides an analog voltage signal back to the BCM that will increase as the brake pedal is applied. When the brake is applied, the BCM will then apply battery voltage to the left and right stop/turn signal lamp supply voltage circuits and the center high mounted stop lamp (CHMSL) supply voltage circuit illuminating the stop lamps. At the same time the BCM applies battery voltage through the signal circuit to the transmission control module (TCM) and the engine control module (ECM) indicating that the brakes are applied.
Ground for the stop lamps is supplied as follows:
• G402 provides ground for the left rear stop/tail/turn signal lamps
• G403 provides ground for the right rear stop/tail/turn signal lamps
• G301 provides ground for the CHMSL
The stop lamps on this vehicle will not illuminate unless the ignition is in the accessory, run, or crank positions. When the ignition is in the OFF position the stop lamps will not illuminate when the brake pedal is applied.
Battery voltage from the LT TRN/SIG and RT TRN/SIG fuses located in the rear fuse block is also used by the body control module (BCM) for stop lamp operation.

Turn Signal Lamps
Battery voltage supplied to the body control module (BCM) from the fuses listed below is used for turn signal and hazard lamp operation.
• LT TRN/SIG fuse for the left turn signals
• CTSY/RF TRN fuse for the right front turn signal
• RR TRN/SIG fuse for the right rear turn signal
When the turn signal switch is place in either the LEFT or RIGHT position, ground from G300 is applied through the turn signal switch signal circuit to the BCM indicating the turn signal request. In response to this signal, the BCM applies a pulsating voltage to the front and rear turn signal lamps supply voltage circuits cycling the lamps ON and OFF. At the same time the BCM sends a GMLAN serial data message to the instrument panel cluster (IPC) to cycle the appropriate turn signal indicator ON and OFF.
Ground for the turn signal lamps is supplied as follows:
• G104 provides ground for the left and right front turn signal lamps
• G402 provides ground for the left rear stop/tail/turn signal lamps
• G403 provides ground for the right rear stop/tail/turn signal lamps

Do you have a factory scan tool (tech2) ? Your best bet , take it to the dealer .

You can purchase a haynes or chiltons guide those will have that information and more. Have you replaced all of the bulbs within that light? sometimes one bad light can make them all not work right.
Thanks,
Lee

you have a broken wire or pinched wire trace wires down from tail light until you find problem and check all the other bulbs in the other lights

No, because the left side is still working. The loose wiring was to the multifunction switch (turn signal).

Power gores through the turn signal switch to the brake switch on the brake pedal, then to the rear lights. Does the highmount brake lamp work?
At the RH lamp socket, Measure the voltage between the RH rear lamp C4032 pin 3, circuit 5 (OG/LB), harness side and ground. Should be 12 volts.

try that first.

Did you change the front and rear bulbs?

Check the bulbs if the bulbs are good suspect the panel that the bulbs go into. Which are also called the sockets you may have to replace the sockets this is not an uncommon problem.

it should be a 1157 bulb

if it's only the rear turn signal that does this, check the plug where the bulb snaps in. if loose or bad connection to bulb, it will sometimes work and sometimes not. if its both the front and rear turn signal bulbs, could be the combination switch. these were common failures on fords

Have you checked the breaklight switch under the dash? It works off the break peddel arm it could be bad or out of ajustment.

The ford explorer sport track. Will have a short either at the plug of the multi-function switch or 6 inches down where the column bends the wires during tilt.

Due to poor design on Fords part. When you use the tilt often, the wires inside due not have enough relief. They are to tight. My 02 sport track had same problem. Wire actually broke off inside the steering column. Take off the lower then upper plastic around column. You probably have broken or loose wires
