Diagnosing Ford Explorer Corner Lights Problems
Car owners often neglect problems with corner lights because they do not know that these can be the first steps toward a bigger problem. We recommend that you avoid a bigger damage by solving the simple problems with your Ford Explorer corner lights immediately.
Lights would not turn off
It isn't really hard to miss that your car's corner lights are lit for a whole day-or since last week, if you're the observant type. There are also times when the lights won't turn off or on unless you flicked the switch or turned off the engine at least a hundred times.
As you may have guessed, this is not a problem with the light bulbs or with the electrical connections connected to the bulb; if these were the cases, then the lights shouldn't turn on. Since the corner lights are controlled by the car's ICU, the ICU would be the best suspect for this problem followed by the light switch. If the lights still go on at the first flick of the switch, the problem is likely the light switch and not the ICU; the wires there may be loose or burnt. If your problem is with the ICU, replacing it can possibly be the only way to go. However, it would help to consult a trusted mechanic before doing so.
In an opposite case from the above, corner lights can also not light up. There are two things to check for this problem: the bulb and the wires. Regardless if only one or both bulbs light up, there is a risk that the problem is not the bulb. Most of the time, the wire causes the problem. Since the assembly is constantly exposed to heat, the wires are prone to melting. If this is the case, then you just simply need to replace the wires.
Loose corner light assembly
The Ford Explorer corner light is another part that needs to be compatible with the rest of the assembly. If you bought a second-hand car, you should inspect the corner lights. If the previous owner installed an incompatible corner light, that would mean that the assembly is only being held by screws; a few more shakes would cause the entire assembly to fall out. Make sure that the corner lights are right for your car model by cross-checking the specs of the lights with your car's manual.
