Why are my Turn and stop lights not working?
Some lighting functions like turn and stop lights that do not remain on all the time will need to draw less power and they may operate properly, even when there is a ground problem. But when always-on lights, your headlights, are turned on the total current draw may be more than can be passed by the harness due to the weak ground connection.
What should I do if my turn signal is not working?
A bolt or unpainted metal bracket will do. Then touch the socket contacts with your test light tip and have your assistant operate the turn lights. The test light should flash. If it does, check the ground connection at the socket.
Is there a turn signal for both left and right?
Although some models use a separate light for the left and right turn indicators, other models use a single light for both turns. If your instrument panel has only one indicator light for both left and right, check the flasher unit. Some vehicle models combine the brake light, taillight and turn signal into one light bulb.
How to tell if a tow light is on or off?
On the 4-pole pin for the yellow wire you should detect a steady signal when the brake is pressed and an on-and-off signal when the left turn signal is on. On the pin for the green wire you should detect a steady signal when the brake is pressed and an on-and-off signal when the right turn signal is on.
Why is the right turn signal light not working?
Back probe the wire that supplies power to the right turn signal lights; the test light should not light. If the test light illuminates, replace the switch. Repeat the test, but this time operate the switch so the right turn signals light.
What should I do if my light fixture is not working?
Check the connections at the switch and make sure that they are tight. Be sure that the power is off to the circuit that you are working on. With the power shut off, check the wire connections at the light fixture and at the breaker panel to make sure they are all connected tightly.
What should I do if my light bulb limit switch is faulty?
Make sure there is enough air circulation around the canister, which will prevent the fixture from overheating. The limit switch may be faulty. If the light bulb wattage is correct and there seems to be proper ventilation around the light fixture, then consider replacing the limit switch or the entire light fixture.
