I drive a 2005 saturn relay. The left front blinker will not work. We have changed the bulb and it still won't work. All the others work


Why is it you don't take it to the repair shop ? Do you know about automotive electrical circuit's an testing ? Viewing a wiring diagram an using a DVOM - digital volt ohm meter to test . You changed the blub ,but testing the circuit for B+ voltage is what you should have done . Not a fuse problem either . the other's work . Checking for DTC'S - diagnostic trouble code's would be a good first step . The BCM - body control module turns it on an off .

Turn Signal Lamps
The STOP/TURN fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the body control module (BCM) for the turn signal lamps. When the turn switch is placed in the left or right position, ground is applied to the BCM on the left or right turn signal switch signal circuit. The BCM then applies voltage to the appropriate front and rear supply voltage circuits.
Grounds for the various lamps are as follows:
• G100 supplies the right front lamps
• G101 supplies the left front lamps
• G400 supplies the right rear lamps
• G401 supplies the left rear lamps

DTC B3948 Left Front Turn Signal Circuit
When the turn signal switch is placed in the left turn position, the body control module (BCM) cycles positive voltage ON and OFF to the LF turn signal lamp through the left front turn signal lamp supply voltage circuit. The front turn signal lamps illuminate steady for daytime running lamp (DRL) operation.

Your best bet , take it to a qualified repair shop.

Where's is the fuse located for my brake lights on my 2007 Pontiac g6 and rear defrost fuse


Stop Lamps
your br
The brake pedal position sensor is used to sense the action of the driver application of the brake pedal. The brake pedal position sensor provides an analog voltage signal that will increase as the brake pedal is applied. The body control module (BCM) provides a low reference signal and a 5-volt reference voltage to the brake pedal position sensor. When the variable signal reaches a voltage threshold indicating the brakes have been applied, the BCM will apply battery positive voltage to the stop lamps, transmission control module (TCM), engine control module (ECM), and stop lamp relay coil side. When the stop lamp relay receives battery voltage from the BCM, the relay coil is energized and the stop lamp relay switch contacts close applying battery voltage through the STOP LP fuse to illuminate the center high mounted stop lamp (CHMSL).
I'd say you have more then a bad fuse ,just reading how the brake lights function .You should have it hooked up to a professional grade scan tool ,one that can check for DTC'S - diagnostic trouble codes in the BCM - body control module !
  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
  3. With a scan tool, observe the Brake Pedal Position Sensor parameter in the data list for the body control module (BCM).
  4. Apply and release the brake pedal.
Does the scan tool display a change in the voltage?

  1. Install a scan tool.
  2. Turn ON the ignition, with the engine OFF.
Does the scan tool display DTC C0278 00?

Recalibrate the brake position sensor.

Circuit Description
DTC C0870
The body control module (BCM) applies a ground through the brake sensor reference low circuit to the brake pedal position (BPP) sensor. The BCM supplies a 5-volt reference through the brake sensor reference voltage circuit to the brake position sensor. When the brake pedal is being applied, the BPP sensor then sends a variable voltage signal through the brake sensor signal circuit to the BCM.
Circuit/System Verification
  1. Ignition ON, observe the scan tool Brake Lamp Cmd. parameter as you apply and unapply the brake pedal. The parameter should change between OFF and ON as the brake pedal is applied and released.
  2. ?‡'
    If the parameter does not change as the brake pedal is applied and released, refer to Brake Pedal Position Sensor (BPPS) Malfunction.

  3. With a scan tool, command the LR Stop/Turn Signal Lamp ON and OFF. The LR turn signal should turn ON and OFF when changing between the commanded states.
  4. ?‡'
    If the LR stop lamp does not illuminate when commanded, refer to Stop Lamps Malfunction.

  5. With a scan tool, command the RR Stop/Turn Signal Lamp ON and OFF. The RR turn signal should turn ON and OFF when changing between the commanded states.

If the RR stop lamp does not illuminate when commanded, refer to Stop Lamps Malfunction.

Brake lights went out so I changed a blown fuse,now the brake lights wont shut off,so I replaced the brake switch at the pedal and still have the same issue,lights wont go off.


Which fuse did you replace ? The one in the under hood fuse box or one of the two in the I/P fuse box . Do the CHMSL - center high mount stop lamps work correctly ? Here is a description how they work .
Stop Lamps
The STOP LP 25 A fuse in the underhood fuse block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to both the STOP 15 A fuse and the CHMSL 10 A fuse in the I/P fuse block, and to the turn signal/hazard module. The turn signal/hazard module then supplies voltage to both of the trailer rear turn/stop lamp supply voltage circuits. The voltage from the CHMSL 10 A fuse is to the center high mounted stop lamp (CHMSL) and the trailer jumper harness. The voltage from the STOP 15 A fuse is to the stop lamps, throttle actuator control (TAC) module, and the cruise control.
Does yours have trailer light hook up ? If so check trailer wiring connector for corrosion . Also check the turn signal / hazard module .

Would fuse cause rear brake lamp and turn signial to stop working ? change bulb did not help


I doubt it. Usually you have one fuse for all 4 turn signals.
You might try the emergency flashers and see if they work that way.
The problem could be in the lamp socket or the turn signal switch.

The turn signal switch is most likely the problem,but change the flasher for the turn signals first,some times this is all that it is.

Trailer connection not working need to know which fuse to change 2005 Ford F150 Lariat


Trailer Tow reversing relay ( non serviceable ) and the Trailer tow parking lamp relay are both fed from Fuse #10 ( coil on reversing relay is fed from reverse lamps & coil on parking lamp relay is fed from the parking lamps ).

Trailer Tow battery charge relay is fed from Fuse #106 ( coil is fed by fuse #13, hot in start / run position from key ).

Right Stop / Turn is fed from Fuse #36 ( powered from MFS circuit for truck stop/turn )
Left Stop / Turn is fed from Fuse #42 ( powered from MFS circuit for truck stop/turn )

Rear brake lamps


I worked for a GM dealership,The problem maybe in the turn signal switch. The brake lamp circuit is wired into it to turn off cruise control.The third brake lamp is a circuit by itself.
