BMW Z3 Side Marker Lights
What to Do When Your BMW Z3 Side Marker Lights Malfunction
Designed to provide additional security at night and on days with poor visibility, your BMW Z3 side marker lights allows you to navigate roads safely. These lights act as warning lights to other motorists, making lane switching easier. Like any other automotive lights, the side markers experience breakdowns. Sometimes, it's difficult to pinpoint where the problem lies. Here are some of the things that you need to watch out for and what you need to do work out the problem:
Burnt-out bulbs and busted fuses
Just like the other lights in your vehicle, the side marker lights may not function if there's a burnt-out bulb inside the assembly. Replacing the bulbs is rather straightforward and takes only a few minutes to do. Once the fender and side marker light cover are out of the way, you can unscrew the bulb of its socket and install the new one. If that doesn't take care of the problem, look inside the fuse box and check for damaged fuses. The fuse box holds all the other lights fuses, so make sure that you are pulling out the right one.
Loose wirings hamper the electricity flow from the battery to the side marker lights. Lightly tugging at the wires will give you an idea which ones need to be attached securely to the assembly. Turn on the marker lights to see if the process worked.
Lights not blinking
Your car's side marker lights are made to blink regularly. If the side markers don't blink at all (or if a bulb on one side blinks and the other one doesn't), that means there's a problem with either the switch or signal relay. Assuming that there are no burnt-out bulbs or defective fuses, you can replace the relay, which is located near the fuse panel. If the lights continue to blink, the problem could be due to a faulty switch. On some occasions, the side marker lights continue blinking even after the turn signal is not used. In this case, turning off the blinker flasher might help. If it doesn't, check on the fuse and replace it if necessary.
