What the Glow Plug Light (Diesel) Means on a Chrysler Town & Country
On a diesel Chrysler Town & Country, the coiled glow-plug light is normal at start-up: it shows the glow plugs are pre-heating the cylinders. You wait for it to go out before cranking. If it flashes after warm-up, it signals a glow-plug or engine management fault.
