Automotive relays are designed to open and close electric circuits in order to produce certain signals when a button is pressed. They allow for the control of electronic devices in a vehicle. Relays are used in the engine start systems, windscreen cleaning systems and exterior and interior lighting.

5 tips on maintaining and replacing automotive relays

  1. Automotive relays don’t have a defined service life, therefore, they only need to be replaced when they stop working.
  2. Working with electrical wiring requires specialist skills and equipment, therefore, it is recommended to visit a repair shop if any problems with the system arise. Bes ides, the relay replacement may require laborious dismantling of other parts.
  3. It is also advised to visit a repair shop to check automotive relays. This is usually done by supplying some voltage to the input contacts, the resistance is then measured with a multimeter. If the part is fault-free, there is a click when voltage is supplied and resistance is near zero. If this is the case, other system elements should be inspected.
  4. The location of relays differs depending on the car make and model. Read the vehicle manual to find exactly where relays are located in your car.
  5. If the contacts are slightly oxidized, they should be cleaned with special chemicals.

Common problems with automotive relays - causes and symptoms

  • Contact oxidation. This is caused by moisture getting in to the system, often due to incorrect installation. Sometimes however, exposure to water is almost inevitable due to the location of the device - in an engine compartment, for instance. As a result, operational malfunctions of the corresponding electric mechanism (e.g., a starter) can be observed.
  • Thermal damage to contacts. This can be caused by a device being on for an extended period and overheating or by a voltage spike in the onboard network. An indication of this issue is that the switch doesn’t work. On the examination, melted wiring can also be noticed.
  • Broken internal winding. This can be caused by strong vibrations when the car is in use. If this problem occurs, the device doesn’t perform its functions.
