    The book says with the 3 door to go thru trunk and remove the screw and pull out casing. There is only a black wire and when I gently tug it, it doesn't seem like it will come out or that it's the right thing. Any help?

08 Buick lucerne cxl. Third brake light works as well as front signal lights. No rear brake lights or turn signals. Tail lights and headlights and third brake lights works. Bulbs good. Help

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

If it is the blinker switch why do I not have brake light on right rear side as well as no turn signal

The brake light circuit runs through the blinker switch, which is how the turn signal is able to override the brake light.

1998 chevy lumina: rear window brake light not working, left brake light not working, rear left turn signal not working

See if bulbs have burnt out in the left brake light and rear turn signal (one bulb if combined) and also rear center high mount brake light.

If the left turn signal has a slower speed than the right turn signal, this is a symptom of a bulb or bulbs burnt out.

Usually, the wiring is not a problem, but I would not rule wiring (or sockets) as a problem out.

Good luck on this repair.

2005 mustang right turn signal wont work but bulb lights when lights are on. When signal is on only the first bulb blinks (and twice as fast as left signal) and second signal bulb doesn't work at all.

Replace the bulb(s). Tail light bulbs have more than one filament. One is for the brakes and one is for the turn signals. The reverse light is a light all by itself. When the filament for the turn signal goes out the brakes will still all light up, but the turn signal will not.

Check for power at the turn signal switch. White wire comes from brake switch switch into the turn signal switch. The brake light switch is working because the high mount brake light is working..right? Do the turn signals work ok? if so, then the wiring is OK. The brake signal wires that come out of the turn signal switch are dark green(right) and yellow (left).

When braking, green turn signal lights up and right rear brake light does not come on. (have replaced brake light)

Do you have a trailer harness? If so, your harness has a short in it.
Remove it and throw it away; cheaper to replace it than to repair it.

If not, you have a short in the socket at the brake lamp
