Check for a turn signal fuse: A quick check of your car's fuses should indicate whether or not a fuse needs replacing.Furthermore, a malfunction here could result in the corresponding left or right turn signal blinking too fast, or even too slow. If it's been replaced with a part that's not quite compatible, this may change the speed of your indicator flashing. Check the turn signal relay: This device actually controls how fast your indicators flash and is configured for your car by the manufacturer.

Naturally, any electrical components need a certain amount of power to work, and if they aren't getting enough, there will be problems.

You can use a test light or multimeter at different points to check that electricity is flowing properly, or have a professional examine the connectors, harness, housing, and sockets. They could be affected by rust or the connections could break from friction or overheating. Check for a bad grounding connection: The wires connecting the various components in the circuit can wear out just like anything else.Check that all filaments are in good condition across all exterior lights. Be sure not to touch the glass with ur fingers, as residual oil could cause it to explode when heated. Check the bulbs: Check the rapidly-flashing bulb in case it is loose in the fitting - make sure it is secure and try the indicators again.Here are some options to check for faults:

While the problem could be with the turn signal flasher itself, a rapid flash could signal a wiring or relay issue.

This usually means something is wrong, and in some cases, one of your other lights may have stopped working while the flash of the functional bulb seems to have doubled. Sometimes the audible warning will be much more rapid, and the flashers will blink much faster. Generally, when you flip the indicator stalk to engage your turn signals, you see a consistent blinking from the indicator lights on your dashboard cluster, and you'll hear an audible confirmation that the indicators are flashing.
