The glow plug light is an indicator that the engine is not getting enough heat. This can be caused by a number of things, such as a faulty thermostat, a restricted radiator, or an engine that is not running at its proper operating temperature. If the glow plug light stays on, it is important to have the vehicle checked by a qualified technician to determine the cause.
If your glow plug light stays on, it’s likely due to a problem with the glow plugs or the wiring. The glow plugs are responsible for heating the air in the cylinders so that the engine will start. If they’re not working properly, the engine may not start.
There are a few things you can check to troubleshoot this issue: First, make sure that all of the glow plugs are tight and securely in place. If any of them are loose, they may not be getting power and could be causing the light to stay on.
Next, check the wires going to the glow plugs. Make sure they’re all connected and there aren’t any frayed or broken wires. If everything looks good with the physical components, then it’s likely that there is an issue with the Glow Plug Control Module (GPCM).
This is a computer module that controls when power is sent to the glow plugs. It’s possible that it has gone bad and needs to be replaced. If you’re having trouble diagnosing or fixing the problem yourself, it’s best to take it to a mechanic so they can properly diagnose and fix the issue.

Glow Plug Light on While Driving
If you’re driving and your glow plug light comes on, don’t panic. This is usually just an indication that the engine is cold and the plugs are heating up. However, if the light stays on after the engine is warmed up, it could be a sign of a more serious problem.
In either case, it’s best to pull over and investigate as soon as possible. If the engine is cold: The most likely explanation is that the glow plugs are doing their job. When you start a cold engine, the glow plugs heat up the air in the cylinders so that the fuel will ignite more easily.
Once the engine warms up, they’re no longer needed and will turn off automatically. If your car has been sitting for a while or if it’s very cold outside, this process can take a minute or two. Just keep driving until the light goes out.
