How does a glow plug relay work?

The glow plug control unit uses a glow plug relay to switch the current for the glow plugs on and off. The more glow plugs monitored by a control unit, the higher the current the circuit will need. To reduce the current needed, glow plugs are often distributed across two circuits, with two glow plug relays.

What causes glow plug relay failure?

Like most other car parts, the glow plug relay can wear out naturally over time. Exposure to extreme temperatures as well as fluctuating electrical currents and misfiring injectors can also play a part in accelerating the process.

Is it safe to drive with a faulty glow plug?

No, it is not safe to drive with a faulty glow plug. An improper combustion chamber temperature will lead to inadequate fuel ignition, resulting in the misfiring or rough running of your engine. This could potentially put you in danger if you are driving at high speeds or in hazardous conditions.

What happens when a glow plug relay fails?

Problems Starting the Engine
Engine performance issues are at the heart of glow plug- and glow plug timer-related problems. When the glow plugs can’t generate enough heat and power to the engine, or when the timer relay isn’t working properly, it will have a difficult time starting smoothly, or it may not start at all.
