Basic Turn Signal and Flasher Problems
Most problems in the turn signal or flasher system can be reduced to defective flasher or bulbs, which are easily replaced. Occasionally, the turn signal switch will provide defective.
F = Front | R = Rear | ● = Lights off | ○ = Lights on |
Condition | Possible Cause | |
Turn signals light, but do not flash. | Defective flasher | |
No turn signal on either side. | Blown fuse. Replace if defective. Deflective flasher. Check by substitution. Open circuit, short circuit or poor ground. |
|
Both turn signals on one side don't work. | Bad bulbs. Bad ground (or either) housings. |
|
One turn signal light on one side doesn't work. | Defective bulb. Corrosion in socket. Clean contacts. Poor ground at socket. |
|
Turn signal flashes too fast or too slow. | Check any bulb on the side flashing too fast. A
heavy-duty bulb is probably installed in place of a regular
bulb. Check the bulb flashing too slowly. A standard bulb was probably installed in place of heavy-duty bulb. Loose connection or corrosion at the bulb socket. |
|
Indicator lights don't work in either direction. | Check if the turn signals are working. Check the dash indicator lights. Check the flasher by substitution. |
