Reasons Why Jeep Lights Won’t Turn Off
A Jeep is equipped with different types of lights. So, you’ll discover numerous reasons. Most vehicles apart from Jeeps share the same symptoms of light switching-off issues. I’ll discuss these reasons according to the Jeep’s light position in the Jeep. So, follow this discussion if you’re unaware of these bizarre reasons behind light turning-off problems.
Internal Jeep Lights
Dome lights and decorative lights are known as internal Jeep lights. These lights help you to see inside the Jeep at night. However, they fail measurably if there are faults with car parts and switches.
(i) Activated Control Knob
A turned-on control knob activates the Jeep’s dome light. You can’t turn off the light when your Jeep’s switch is fixed to a particular position. Sometimes, the brightness regulator doesn’t work correctly. As a result, the dome light stays on for a long time, causing fast battery drainage.
(ii) Broken Door Switch
Generally, an exposed switch or a stuck switch is the culprit behind illuminated Jeep interior lights. You’ve to check each button individually to turn off the lights.
It indicates a broken door switch if you don’t hear any noise while pressing buttons. Your Jeep’s door will always stay open due to a defective door switch leaving the lights on.
Headlight Difficulties
A Jeep’s headlights are one of the most critical parts of a vehicle since they help you to detect other vehicles at night. Well, you can guess that you’ll go through lots of difficulties if these lights are turned on in broad daylight.
(i) Faulty Engine Timer
Some Jeep headlights stay on for moments even after you’ve turned off the engine. So, it shouldn’t concern you since it’s a default feature. However, a faulty engine timer keeps the light on after shutting off the engine.
(ii) Damaged Relay
When the operating system receives wrong relay information, the light stays on. Relays signal the system about the required time before turning off the headlights.
But, a damaged relay fails to send a smooth signal causing the illumination of headlights. Your Jeep’s headlights will flicker when there’s a relay-related issue.
(iii) Single Headlight Is ON
Malfunctioning automated lighting is another potential reason for this issue. One light may stay on after the automatic shutdown period. You can confirm this problem while applying the parking brake a few times. Sometimes, a burned-out headlight is another reason behind this problem.
Faulty Parking Light
Parking lights are a must while you’re parking your Jeep. With defective parking lights, you’ll face both major and minor issues while parking your Jeep. Check out the signs before changing the Jeep’s parking lights.
(i) Stuck Parking Light Switch
You’ll find the parking light switch near the steering wheel. This switch gets stuck with time. As a result, you’ll face some difficulties while turning off the parking light.
(ii) Defective Turn Signal Relay
The turn signal relay gets stuck occasionally. A damaged spring in the signal arm also hampers the signal relay’s duty. So, the signal relay is likely faulty when the parking light stays on even after you’ve pressed the switch.
