Troubleshooting Tail Light Wiring Problems
When your 2007 Chevy Impala tail lights are not working, there may be several reasons why. Some of the most common causes of tail light failure include blown fuses, damaged bulbs, faulty wiring, and faulty light housings.
Check the Fuses
The first step in troubleshooting tail light wiring problems is to check the fuses. Fuses protect the electrical system from damage caused by power surges and short circuits. You can find the fuse box in the driver’s side of the dashboard. Refer to your owner’s manual for the location of the specific fuses for the tail lights.
If you find a blown fuse, replace it with a new one of the same rating. If the fuse blows again, you may have a short circuit in the wiring. Proceed to the next step.
Check the Bulbs
If the fuses are not the problem, check the bulbs. You can access the tail light bulbs by opening the trunk and removing the tail light assembly. Check each bulb to see if it is functioning properly. If any of the bulbs are damaged, replace them with new ones. If the bulbs are all intact, proceed to the next step.
Check the Wiring
If the fuses and bulbs are not the issue, the wiring may be the culprit. The wiring may have become corroded or damaged over time, leading to poor connection or no connection at all. To check the wiring, you will need a multimeter and the wiring diagram.
First, remove the tail light assembly and disconnect the wiring harness. Set the multimeter to measure resistance and touch one lead to each wire. The multimeter should read close to zero if the wiring is functioning properly. If the multimeter reads infinite resistance, there may be a break in the wiring. Refer to the wiring diagram to identify where the break may be and repair the affected wire. If you are unable to locate the break, it may be best to take your vehicle to a professional auto mechanic.
