How to get power to right turn signal? - Mercedes S-class S500 S55 S430 Exterior Stainless Steel Chrome Pillar Posts Trim Set 2000 2001 2002

Doesn't have a turn signal flasher , use's lighting control module .
Turn Signal and Hazard Lamps The turn signal system consists of:

• turn signal miniature bulbs (13465).
• turn signal indicators in the instrument cluster (10849).
• lighting control module.
• multi-function switch (13K359).
• circuit wiring and circuit protection.

Power is supplied to the lighting control module through instrument panel Fuse 6 (10A). This fuse is hot in START or RUN. The lighting control module is connected to the turn signal switch portion of the multi-function switch. Ground is provided to the lighting control module and the turn signal miniature bulbs through Circuit 57 (BK).
Turn signal functions are performed by double filament bulbs in lamp assemblies located next to the headlamps. The turn/hazard function uses the second filament of the appropriate bulb(s).

• With the multi-function switch in the right turn position, power is supplied to the RH front and rear turn signal miniature bulbs and the right turn indicator in the instrument cluster.
• With the multi-function switch in the left turn position, power is supplied to the LH front and rear turn signal miniature bulbs and the left turn indicator in the instrument cluster.

The left an right turn signals get there power from same fuse ,HZDT/SG fuse 15amp in the left under hood fuse box. through the turn signal hazard flasher module. Here is how they work .
Turn Signal/Cornering Lamps
The HZDT/SIG fuse in the fuse block - underhood - left supplies battery positive voltage to the turn signal/hazard flasher module and have ground at G202. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. The T/SIG fuse in the fuse block - underhood - left supplies battery positive voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, current flow is from the turn signal switch assembly to the turn signal/hazard flasher module. The turn signal/hazard flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument cluster (IPC) indicator. When the hazard switch is pressed, all the turn signal lamps will flash including both IPC turn signal indicators. The left turn signals have ground at G106, G400 and at G402. The right turn signals have ground at G105 and G400. The turn signal switch supplies battery positive voltage to the cornering lamps, the left cornering lamp has ground at G105 and the right cornering lamp has ground at G106.The turn signal switch or the turn / hazard flasher module is bad or there is a wiring problem. Go to you tube an check out a few videos on basic electrical testing ,then get a DVOM - digital volt ohm meter , an wiring diagram an trouble shoot the circuit . There may even be a video on test turn signal circuit .

This is fairly easy to diagnose. Down by the brake pedal there is a switch. You may have to remove some trim panels to access it. There should be one wire with power all the time. There should be another wire that has power only when the brake pedal is depressed. If there is no power on any of the other wires with the brake pedal depressed than the switch is bad.

If there is power than the more common problem is the turn signal switch. I know it doesn't sound like it could be the problem but let me explain how it works. the turn signal and the brake use the same bulb. In order for the correct power source, brake lights or turn signals, to get to the correct bulb the turn signal switch is used. If you are not turning the power from the brake switch is routed through the turn signal switch and then sent to the two brake brake bulbs. If you are turning to the right power from the brake switch is cancelled to the right bulb and replaced by power from the turn signal flasher.

One quick way is to see if the third brake light is working. If it is you know the brake switch is working since power to the third brake light bypasses the turn signal switch.

Good Luck and let me know how it goes!

Has the vehicle been in an accident on the left rear side. First check the bulb to be sure it is not defective, trade it out with the side that works properly to test. If the bulb works well then My thought are you may have a shorted wire. The turn signal flasher works by heat build up within the flasher the heat is caused by the load of the bulbs, the load heats the metal spring causing it to open the circuit then as quickly as it cools down the circuit closes again lighting the bulbs.
There is also a possibility of a defect in the turn signal mechanism on the steering column. The turn signal switch on many models does three different things on many models that use the same bulb element / or bulb for brake and turn on rear of vehicle. It controls the circuit for brake light by sending power both left and right side rear when turn signal is in neutral position then when turn signal is in left turn the switch cancels brake light power to left side rear and supplies flasher power to left side while maintaining brake light supply to the right side rear, and so on opposite when the right turn is chosen on turn signal switch. The turn signal indicators on the dash normally run off the same circuit as front turn signal bulb only which is also controlled by turn signal switch. Front has turn signals but no brake light.
I think there is an additional load on the left side rear turn circuit and it could be either a wire that is shorted or the turn signal switch if the same bulb element is used for both functions.
Often times if trailer lighting is connected the flasher will also blink a little faster because of the extra load of additional bulbs.

it's the grounds if they're both flashing fast it's definitely grounds take a test light and see if its got power goes through the test light grounded to the frame and if the light comes on then it's definitely your grounds

Make sure to check fuses.

You would check the socket with a test light or meter to see if you have power and ground. If no power, the turn signal switch would be the next thing to check.

RT/SIG fuse #11 15amp - I/P fuse box . Fuse Block - I/P
In the center of the instrument panel, beneath the right side of the radio, in back of the right side console access panel.
This fuse is power to the BCM , When you put on the right turn signal , this is a voltage signal to the BCM . With logic ( programming ) the BCM then controls the turn signal !
Turn Signal/Hazard Lamps
The body control module (BCM) is responsible for controlling the turn signals and hazard lamps. When the turn signal switch is placed in either the left turn or right turn position, the BCM receives a signal from the turn signal switch. The BCM then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, the BCM receives a signal from the hazard switch. The BCM then will send an on-off voltage signal to all the turn signal lamps. All the turn signal lamps will flash including both IPC turn signal indicators.
There could be a DTC- diagnostic trouble code stored in the BCM pointing to the problem ! I suggest you take your vehicle to the dealer or a ASE certified repair shop that has the diagnostic tools to find the problem . Just so you don't waste your money replacing parts that don't fix it.

Howdy, No Big Deal, Follow this, Common Power To Left and Right Signal , orange wire to flasher relay for left black wire for right, there are two relays inside flasher module 1 the left and right signal share the other is for the hazards. The is a common ground for the signal lights and hazard so if one side works good ground if the hazard works good ground...maybe power wire from 320 dollar turn signal unit maybe 160 on ebay....hope this helps keep smiling.....Doug in Clermont, Florida
