check for a bulb out.
This vehicle has poor ground connections for the front turn signal circuits. You need to go the dealer and have them install a front turn signal repair kit. It consists of a small repair harness and a modified turn signal bulb socket, plus a modified bulb.
the left turn signal light on my ridgeline does not work but the right side works
Because the signal system is interconnected.Install new bulbs on the left side -including the front side...I realizethey work. You will be surprised.
if your right turn signal does not work then it could be the switch if not then it could be a wiring fault! Could also be turn signal flasher or switch in steering column as stated above
A bad ground.
bulb or turn signal fuse/relay
There are many problems that come with owning a car. If a Left rear brake and turn signal do not work, a person should check the fuses, bulbs and wiring.
bad signal switch on steering column..
could be a bad ground
flasher will not flash when circuit is open or shorted replace left front turn signal bulb
Check the bulbs. A failed bulb can often cause the signal to stop working on that side.
Check the left turn signal bulb. It is probably burnt out.
