Where Is The Mercedes S350 Turn Signal Relay Located?
You’ll usually find the Mercedes S350 turn signal relay in the main fuse and relay box. In most S350 models, this box sits under the hood, close to the driver’s side fender. Some older models have it tucked under the dashboard, not far from the steering wheel. Pop the hood and look for a black plastic box with clips. Under the lid, there should be a diagram to guide you. Owners’ manuals show relay positions, but if you don’t have one, direct labeling or stamped icons on the fuse box can point you in the right direction. Sometimes, the relays themselves are shaped or colored differently so you can spot them at a glance.
What Are Common Symptoms Of A Bad Mercedes S350 Turn Signal Relay?
When a Mercedes S350 turn signal relay starts to fail, you’ll notice a few things change fast. The blinkers might stop altogether. Other times, the lights blink so quick it almost looks like they’re just flickering. Sometimes you flip the stalk, and nothing happens except maybe a faint click from the dash. You could see your dash indicators acting strange—maybe staying on, not lighting up at all, or blinking in a weird pattern. Hazards and turn signals often share a relay, so if both don’t work, that’s another big clue. Ignoring these signs makes driving riskier than it needs to be, so it’s worth tracking down the problem soon.
How Do I Replace The Mercedes S350 Turn Signal Relay?
Replacing the Mercedes S350 turn signal relay isn’t hard and only needs basic tools. Turn off the car and pull the negative cable from the battery. Open the fuse box and find the relay using the diagram. Pull the faulty relay straight out—sometimes it takes a firm tug, but don’t wiggle too much. Line up the new relay with the slot and push it in until it clicks. Hook the battery cable up again and fire up the car. Test the signals. If they work fine, you’re done. If not, double-check your work and give the wiring a once-over. Sometimes a bad fuse can hide behind a relay problem.
Can I Test The Mercedes S350 Turn Signal Relay Before Buying A New One?
Yes, you can test a Mercedes S350 turn signal relay before spending cash on a new part. One quick way is to swap it with another relay in the box that shares the same type—like the horn or maybe the rear defrost. If your problem follows the relay, that’s your answer. Another way is using a multimeter to check for continuity. A working relay usually clicks when you use the signals—no click can mean trouble. If you want to be sure, most shops will test the relay for you or recommend a new one if yours looks suspect.
How Much Does It Cost To Replace A Mercedes S350 Turn Signal Relay?
Parts for a Mercedes S350 turn signal relay aren’t pricey. Relays run $15–$40 depending on the brand and where you shop. Have a shop do it, and you might pay an extra $60 or so in labor, but most owners tackle this one at home. Swapping the relay yourself often only takes ten minutes, and you don’t need special gear. Sticking with a trusted parts supplier helps you dodge markups and get the job done without breaking your budget.
