Usually, depending on your particular model, getting access to the switch electrical connector is the hardest part.įor this test, it is a good idea to consult the vehicle repair manual for your particular model. Troubleshooting the turn signal switch is pretty much straightforward. If necessary, check continuity from each end of the wire, leading from the flasher relay and the turn signal switch.Check outgoing voltage from the turn signal switch to the faulty turn signal side of the circuit.Refer to the 'Checking a Light Bulb Socket for Ground and Power.' Confirm the ground and power connections are working properly.Then, check the sockets for corrosion, wear or damage.First, check the bulbs to see if they are still in good shape: No darkened areas or damaged filaments.You may be dealing with bad bulbs, a bad flasher relay, a faulty turn signal switch, or a bad wire or connector between the flasher unit and the turn signal switch.

If the test light didn't flash, connect your test light to battery power and touch the socket wall (ground) with the tip of the test light.If it does, check the ground connection at the socket. Then touch the socket contacts with your test light tip and have your assistant operate the turn lights.A bolt or unpainted metal bracket will do.

Connect your test light to a good chassis ground.

The test light should flash-otherwise, there is something wrong with the ground or power connections.

Have an assistant operate the turn signal.

After removing the bulb, clip the test light to the socket wall (ground) and touch each socket contact inside with the tip of the test light.
