Where is the relay for Mercedes-Benz A160?
3 Answers
Mercedes-Benz A160 relay is located in the central junction box. Introduction to relay: A relay is an automatic switching component with isolation function, widely used in remote control, telemetry, communication, automatic control, mechatronics, and power electronic equipment. It is one of the most important control components. Precautions for installing cooling fans: The air ducts at the fan inlet and outlet should have separate supports. Do not allow the weight of overlapping pipes to be added to the fan components. During fan installation, pay attention to the horizontal position of the fan. The connection between the fan and the foundation surface and the exhaust duct should be adjusted to ensure a natural fit, and forced connection is not allowed.
I frequently repair Mercedes-Benz cars, especially models like the A160. The relay locations are typically in two spots: one is the small black box in the front left of the engine bay, near the battery or coolant reservoir—it's the fuse box cover. Just unscrew or unclip it to reveal a row of blue or green relay modules. The other spot is under the glove compartment in the passenger cabin. Lift the carpet or floor mat, and you'll find a small cover panel housing the relay center. When searching, don’t rush—first check the owner’s manual for the page number or search online in Mercedes community galleries to avoid pulling the wrong parts. Last week, I helped a neighbor fix their A160; the relay was faulty, causing the headlights not to work. Once I located it, the issue was resolved in minutes—just remember to turn off the engine for safety. Regular maintenance checks can save a lot on repair costs.
As a Mercedes-Benz A160 owner, I find the relay locations relatively easy to access. Most are located under the floor in the front passenger footwell - just lift the mat or carpet to reveal a small cover panel housing various relay blocks. I've tinkered with them several times myself. For instance, when the wiper relay malfunctioned causing washer fluid issues, replacement was straightforward: open the cover, check the manual's labeling diagram to identify it. Detailed schematics are available online - just input your model year to find them. If you're a novice unsure about the process, it's better to visit a dealership or repair shop. Spending a small amount saves hassle. While relay failures seem minor, they can affect AC or ignition systems - early diagnosis ensures worry-free driving.
