Jeep Cherokee Interior Lights Wont Turn On When Door Opens

If your Jeep Cherokee interior lights aren’t turning on when the door opens, it might be due to a few specific reasons such as a blown fuse, faulty door jamb switch, or a malfunctioning interior light switch. But, don’t worry. We’ll walk you step-by-step through these issues and their possible solutions to reignite that typical warm jeep interior glow every time you swing the door open.

Let’s dive in further to unravel the mystery behind this inconvenience and explore the steps you can take to fix the problem without burning a hole in your pocket.

A Close Look at the Door Jamb Switch

The door jamb switch, also known as the door light switch or courtesy light switch, might be the prime suspect when your Jeep Cherokee’s interior lights refuse to turn on. This component is responsible for activating the interior lights when the door is opened.

The symptoms of a defective door jamb switch

One of the most crucial symptoms indicating a faulty door jamb switch is when your car’s interior lights refuse to come on or go off. It might either be due to the door switch being stuck, the electrical contacts being dirty, or the switch being completely damaged.

The remedies to a faulty door jamb switch

Here’s a simple checklist to resolve a defective door jamb switch issue:

– Inspect the door jamb switch for any signs of damage or wear.
– If the switch appears to be stuck, try to free it carefully using a flat-head screwdriver.
– Check for any dirt on the electrical contacts of the switch. If it’s there, use a contact cleaner to remove it.
– If the switch is damaged beyond repair, consider getting it replaced.

Test the Interior Light Fuse

Sometimes, the problem lies within a tiny piece of wire inside your fuse box – the fuse. Typically, each component of your vehicle has a specific fuse assigned to it, and the interior lights are no exception.

Indications of a blown fuse

A blown fuse may inhibit the power from reaching the designated components, in this case, the interior lights. If your Jeep Cherokee interior lights won’t turn on when the door opens, it might be due to a blown fuse.

How to check and replace the blown fuse

Here’s a simple step-by-step guide to check and replace a blown fuse:

– Locate the fuse box which is typically under the dashboard.
– Refer to the fuse box diagram in your vehicle’s user manual to identify the fuse associated with the interior lights.
– Check the fuse visually. If it appears to be broken or burnt, it needs to be replaced.
– If required, remove the old fuse carefully and replace it with a new one of the same rating.

Remember, always ensure your vehicle is turned off before you tinker around with the fuse box.
