When i open my doors the lights do not come on, but do come on when i manually turn my dimmer switch and press the map lights. I have checked fuses and no luck, I have read about a CTM could that be my issue or could it be that the switches in the door frames are bad
Hello. Without knowing the make and model of your vehicle, it hard to definitively give insight on the exact component that has failed.
In general, when the door is opened, the switch turns on the interior lights. If the lights are not coming on, then its possible the switch has failed. It also possible there is a short between the fuse and the door switch.
Does your vehicle have a door ajar warning light, and if so does it turn on when you open the door? The door switch in question would be responsible for this warning as well, and if its not working this would indicate that the switch has gone bad or is not receiving power. The switch is used and impacted often enough that it is more likely to fail than any other component in the circuit.
You will need to test the available voltage at the door switch, and what the voltage is after the door switch is supposed to turn on. If there is available voltage before the switch, and no voltage after, you will need to replace the door switch as necessary.
If you’re unable to fix the issue, have a certified technician, like one from YourMechanic, come to your location and diagnose the electrical issue and firsthand.

Circuit Overload Check you don`t have too many appliances plugged into one power point. One of the common causes of lights not working is an overload of circuits. This happens when too many appliances are connected to one circuit, which means not enough current is available for each appliance or light fixture.
The IOD fuse is a 20 amp fuse located in cavity #51 of the integrated power module (IPM). This fuse provides power to the instrument cluster, diagnostic connector, map lamps, glove box, courtesy lamps, radio and underhood light.
Whenever your car door opens, the puddle light illuminates the ground below, showing off the image of your choice. They got the name “puddle lights” because they help you avoid accidentally stepping out of your car straight into a puddle.
Press the lens (1) to turn ON the map lamp. To turn the map lamp OFF press the lens (1) again. The map lamp and room lamp come on when a door is opened.
Check the light bulb first to see if it has burned out. If so, replace the bulb. Check to see if the bulb is tight in the socket. The constant on-off flow of electricity can sometimes loosen a light bulb in the socket.
Components. A complete sensor consists of a motion detector, an electronic control unit, and a controllable switch/relay. The detector senses motion and determines whether there are occupants in the space. It also has a timer that signals the electronic control unit after a set period of inactivity.
When one light does not work and the others do then a blown fuse may have occurred which needs replacing. If a short circuit has occurred then replacing the fuse and repairing the wiring may be needed. If the car door lights do not work then the door jamb switch often needs replacing.
You may simply have a faulty door switch that is turning on and off when it shouldn`t. Check that all the doors make the interior lights come on and go off when you open and close the doors. You may also what to check the tailgate/trunk. If one of them is not operating correctly then it`s switch may need replacing.
If one or more lights in your home have gone out and your circuit breaker isn`t tripped, what could the issue be? One culprit could be a GFCI (Ground Fault Circuit Interrupter) outlet that has tripped. When experiencing electrical imbalances, GFCI outlets trip much quicker to protect people from electrocution.
The connections are loose
A loose wire, circuit breaker connection, or terminal can lead to problems like flickering lights. Loose connections create resistance, which causes arcing, which can lead to overheating or even electrical fires.
A fuse isn`t required for the lights to work. You can still hook them up directly to the battery. But most people still want to use a fuse to protect the circuit and wiring in case of a short.
The electric wiring for light and fan circuit uses a thin fuse of low current rating(= 5A) because the line wire has a current carrying capacity f 5A.
Door Jamb Switch Kit mounts in a door jamb to activate lights or other electrical items when the door is open. All purpose switch for indoor use on sliding or hinged doors in locations like closets, darkrooms, and walk-in refrigerators.
Puddle lights are the car lamps placed just below the mirror. These illuminate the ground near the car door. Puddle lights prevent you from stepping into a, well, puddle or anything murky when getting into your car. Puddle lights have been around for over a decade now.
Press the button to turn the map lamp on or off. Lights will turn on when any door is open. Push the switch to turn the room lamp on.
Most modern cars have a computer called the BCM or Body Control Module. Depending on the settings, it either has a time delay, or instant turn off that occurs when you lock the car doors. The door lock signal comes in from your remote, the BCM locks the doors, and turns off the interior lights.
If you find that your light switch toggle starts behaving differently than usual (i.e. becoming stiffer than usual or losing its “snap”) it`s a good sign that the switch mechanism is worn and should be replaced immediately by a qualified electrician.
A modern stage lighting system consists of a few main parts- consoles, fixtures, distribution/dimming, and cabling. Whether a small or large system, these basic pieces make every lighting rig function.
Lighting automation system is
used to Switch ON/ OFF lights.
In case of street lights we do not require more brightness during mid night instead; we require more brightness during evening. Lighting automation provide us require brightness as per the requirement without any manual intervention.
Optical sensors are used in other software applications, like digital cameras, mobile phones, and laptops, to measure ambient light levels. A light sensor called a photoelectric device transforms the observed light energy (photons) into electrical energy (electrons).
A control zone is defined as one or more light sources controlled simultaneously by a single control output. Zones may be organized in accordance with energy codes, desired energy savings and flexibility, common lighting equipment (e.g., fluorescent vs.
A smart bulb is an internet-capable LED light bulb that allows lighting to be customized, scheduled and controlled remotely. Smart bulbs are among the most immediately successful offerings in the growing category of home automation and Internet of Things (IoT) products.
This ECU controls the complete light system of a truck or bus including all trailers: Cabin lights, front, side, rear lights, working lights and additional lamps or LED modules.
