Common Problems with the Buick Lacrosse Tail Light Assembly
The Buick Lacrosse is one of the most popular luxury sedans under General Motors ever since it debuted back in 2004. It's a great looking vehicle, but it also has its share of common problems. One of the things that you need to check from time to time would be your Buick Lacrosse tail light assembly. You wouldn't want to get caught driving with a broken turn signal or with flickering tail lights at night. Faulty tail lights and turn signals are easy to troubleshoot and repair, so check out our guide and find out how.
Check your bulbs
Burned out bulbs are probably the easiest problems to diagnose when it comes to tail lights. You'll probably notice it even more if only one light stops working. You simply have to remove the tail light from its mount and check if the filament inside is broken or burnt. You can't repair this so it's best to buy a replacement right away.
Replace a blown fuse
When you check your tail light's bulbs and find out that they're perfectly fine, then you need to look at your vehicle's fuse box next. This is more obvious if the entire tail light assembly won't light up. Just like when inspecting your tail light bulb, you'll need to look at your fuse to see if the thin metal strip inside it is broken. Simply replace the fuse and test your lights again to see if this solves the problem. You'd want to consult your vehicle's manual so you could easily find the fuse that's connected to your tail lights for a quick and easy repair job.
Once you've checked the tail light bulbs and fuse, then the last part that you'll need to check would be the wiring for your vehicle's tail light assembly. You'd want to begin with the connectors that are attached to your vehicle's tail light, to see if they've come loose or have dirty contacts. Over time, the connectors can come loose when you hit a bump or hole on the road. Dirt and grime can also get into the metal contacts and affect their conductivity. Simply clean the contacts and insert the connectors tightly to see if this solves the problem. Otherwise, you might need to use a multimeter or test light to check the electrical connections in your tail lights to see if you have a broken connection or a loose wire.
