1998 mercedes kompressor tail light assembly

If the tail lights seems to be functioning properly, but the brake lights are not working, the mechanic should inspect the brake light switch. If it is not functioning properly, the mechanic will replace it and rewire it to the existing connections. Using a multimeter, the mechanic can check the resistance of the relay. If the bulbs and fuses appear to be working properly, the mechanic will then check the corresponding relay for the tail lights. If so, he or she will replace the bad bulb with a new one. The mechanic will check the filament in the unlit bulb to see if it is broken. Over time, bulbs will eventually fail and need to be replaced. If only one of the tail lights appears to be out, the mechanic should check to see if the unlit bulb is burned out. If so, the mechanic will then replace it with a fuse appropriately rated for the amperage. If he or she suspects a blown fuse, they will remove the corresponding fuse for the tail lights to see if it is blown. The mechanic will begin inspecting the various electrical components of the vehicle by looking at the fuses. If there is no superficial damage, the mechanic will then begin to examine the different components along the electrical circuit. The mechanic will begin by examining the back of the car for any superficial damage like broken tail light covers, and loose, or frayed wiring.

When checking electric components on your vehicle, especially, fuses and relays, the mechanic will bring a multimeter which will help him or her diagnose what specific component has failed. The brake light switch circuit is completed when the brake pedal is pushed, but if the switch has been pushed out of place or is not connecting properly, the brake pedal may not be able to complete the circuit, meaning that the lights will not illuminate. A vehicle with a bad relay or bad ground may not be able to successfully power your rear lights.īad Brake Light Switch: If the rear lights illuminate normally but do not become brighter when braking, the brake light switch may not be functioning properly. A wire that is not grounded properly is unable to protect the circuit and provide an outlet for excess charge that build up. A relay may also fail because it is not grounded properly. A burned out bulb will not affect the circuit of the entire rear light system, and the other rear light should continue to function normally.īad relay: A relay transfers power from the battery to the lights themselves, but when a relay fails, the connection is unable to be completed. When the filament breaks inside a bulb, it cannot illuminate the gas inside the bulb. Sometimes when a taillight lens cracks or breaks, it can allow moisture to enter the lens and cause a short circuit, blowing the fuse.īurned Out Bulbs: In the case where only one of your rear lights appears to be out, the cause is most likely a burned out bulb.

When a fuse blows, it prevents the circuit from completing, in this case preventing the rear lights from illuminating.
