Based on industry averages you can expect to pay between $3.49 and $9.59 for a Mercedes S63 turn signal relay.
Where Is The Mercedes S63 Turn Signal Relay Located?
The Mercedes S63 turn signal relay sits inside the fuse and relay box. Most models place this box under the hood on the passenger side, though some have it in the trunk. To get to the relay, lift the cover off the fuse box and scan the labeled guide tucked inside or printed on top. Sometimes you need to slip out a trim panel or two. Wireless diagrams or the owner's manual help, but not always. Some years rework the layout, so you may have to look for the actual part instead of relying only on charts. Once spotted, you’ll see a small, rectangular module among the other relays.
What Are Signs Of A Failing Mercedes S63 Turn Signal Relay?
A bad Mercedes S63 turn signal relay makes itself known in a few clear ways. The signals might not turn on at all, or they may start blinking faster than normal. Sometimes, one side will flash while the other goes dark. At times, the indicator lights stay stuck either blinking or stuck off, refusing to reset. Instead of the usual click, you might hear nothing or a burst of frantic ticking. Signal lights that quit halfway or behave strangely are warning signs. If the hazard lights act up, that often ties back to the same relay too.
How Do You Replace The Mercedes S63 Turn Signal Relay?
First, cut the power by disconnecting the battery. This avoids accidental shorts. Find the relay inside the fuse box, which should now be open. Grab the relay and pull it straight out, steady and slow, wiggling as needed. Take your new relay and line up the metal prongs with the slots. Press it down until you feel it lock in place. Hook the battery back up, then test the signals right away. Snap a photo of the box before pulling anything, in case you lose track of what goes where.
Can The Mercedes S63 Turn Signal Relay Cause Other Light Issues?
Yes, a faulty Mercedes S63 turn signal relay can trouble more than the blinkers. Some drivers stumble on hazard lights that won't work, or brake and tail lights acting up when the relay fails. These quirks often confuse owners, since one dead relay can send several bulbs into chaos. If other light problems join the mix—anything from warning lights to a single signal not firing—don't rule out the relay. Sometimes, resolving one relay issue brings several systems back to normal.
How Much Does It Cost To Replace The Mercedes S63 Turn Signal Relay?
Most folks pay anywhere from $50 to $200 if they use a pro, with the part and labor both bundled in. Do-it-yourselfers often spend less, as the relay alone usually runs under $50 at most shops or online. Luxury brands like Mercedes carry higher hourly rates, which pushes dealer repair costs higher. Swapping the relay yourself lowers the cost by a fair margin, needing just a few tools and the right relay.
