The front fog light relay of the Santana is located in the engine compartment, on the left side of the battery. Introduction to relays: A relay (English name: relay) is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in the input quantity (excitation quantity) reaches the specified requirements. Function of relays: It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is usually used in automatic control circuits and is essentially an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit conversion in the circuit.
I know the front fog light relay on older Volkswagen Santana models is usually tucked inside the fuse box under the driver's side dashboard – you'll need to crouch down to spot it. The box sits right in front of your left knee, and its cover can be pried open with a fingernail. The relay is a black rectangular block about the size of a matchbox, with metal contact pins. Common positions are slot 100 or 53, depending on your specific model. If the fog lights aren't working, don't rush to replace the relay – first check that the 15A fuse labeled 'Fog Lamp' in the driver-side fuse box isn't blown. I've replaced this part myself; you'll need a Phillips screwdriver and flashlight. Always disconnect the negative battery terminal before replacement to avoid short-circuiting the board. With older cars' brittle wiring, connectors may snap if forced – spraying some WD-40 as lubricant helps with removal.
