The average cost of a Mercedes CLS55 turn signal relay is between $9.59 and $9.59.
Where Is The Mercedes CLS55 Turn Signal Relay Located?
Finding the Mercedes CLS55 turn signal relay doesn’t have to turn into a hunt. Most CLS55 models hide the relay inside the front fuse box, right under the hood next to the passenger side firewall. Pop the hood and you’ll spot the fuse box tucked there. Some years move it to the trunk fuse box, near the battery. Mercedes likes to keep us guessing, so the exact spot can shift with the model year. Take a look at the diagram on the fuse box lid; Mercedes usually labels the relays there. Sometimes, you may see three or four relays grouped together, looking pretty much the same. If nothing’s marked, pull the suspected one and check the connector layout to confirm it handles the turn signals. The manual breaks it all down, if you have it handy.
What Are Symptoms Of A Failing Mercedes CLS55 Turn Signal Relay?
If the Mercedes CLS55 turn signal relay starts to go, you’ll notice right away. First, you might get a fast blink on the dash, but all the bulbs still work. Or you push the turn stalk and nothing happens—no tick, no flash. Sometimes, you’ll hear the click under the dashboard or in the fuse box, but no lights outside. You might lose just one side, or both. Hazards can glitch too, since they depend on the same relay. There may be moments where the signals flicker on for a second, then cut out and leave you guessing. Usually, this starts out as a random issue, then becomes harder to ignore as the relay fails further.
How Do You Replace The Mercedes CLS55 Turn Signal Relay?
Swapping out a Mercedes CLS55 turn signal relay takes a steady hand and a little patience. First, disconnect the negative battery cable—don’t skip this. Head to the fuse box where your relay lives. Open it up and, using the diagram, pick out the right relay. Try to work with your hands or a plastic trim tool to avoid scratching or bending things. Pull straight up to remove the old relay. Take the new relay, line up the metal pins, and push it in until you feel it click. Reconnect the battery, and give your turn signals and hazards a quick test. Usually, this job wraps up in about twenty minutes.
Can The Mercedes CLS55 Turn Signal Relay Cause Electrical Issues?
A bad Mercedes CLS55 turn signal relay creates more than turn signal drama. You might notice blown fuses popping up, or the battery mysteriously draining overnight. Dashboard warning lights can start coming alive when you least expect it. Sometimes, headlights or other circuits flicker because the relay’s built-in switch won’t open or close like it should. If these problems creep up after you know bulbs and fuses check out fine, replacing the relay is a smart move. It’s small, but it can trigger more headaches if you leave it alone too long.
Is There A Difference Between Oem And Aftermarket Mercedes CLS55 Turn Signal Relays?
Plenty of drivers wonder if an aftermarket Mercedes CLS55 turn signal relay measures up to the original. OEM relays slot right in and tend to last. Aftermarket brands can cost less, but sometimes cut corners—cheap plastics, questionable contacts, or loose fits. If you stick with a proven aftermarket name, you usually get good value, but those rock-bottom budget relays may cause issues. Squealing, buzzing, or lights that behave oddly come up more with off-brand options. If you want reliability and no hassle, OEM or a solid, reviewed aftermarket brand is the safer play.
