If your left and right signal lights aren't turning on, first check the fuses related to the turn signal system, as a blown fuse can cause both signals to fail. Additionally, inspect the bulbs to ensure they are functioning properly, as burnt-out bulbs can also lead to this issue. If both fuses and bulbs are fine, the problem may lie in the turn signal switch or wiring, which may require professional diagnosis and repair.
Bad turn signal flasher.
Bad ground.
Replace the turn signal flasher relay.
Its the turning signal/flasher module, left side of dash behind the fuse box. Its a dealer part only about 98.00
Check ground circuit Check bulbs they are duble filamented one may be burned out Seems to me there is a wire crossed at the harness. I think the vehicle left turn signal wire is hooked up to the trailer tail lights wire. Usually there are four wires at the trailer harness, yellow, green, white, and brown, The brown wire is usually the tail lights and side marker lights, the white wire is ground, the yellow and green go to the left and right signal lights.
If the right one works,it might be a bad bulb or a bad ground.
Yes, that would be your signal lights, the left set for left turns and the right set for right turns.
my left turn signal on my 1997 dodge conversion van works fine,the right signal lights but does not blink,,,,any ideas
Sounds like a blown bulb somewhere on the righthand signal side.
Sounds like you simply have A burned out bulb, Turn the signal on and look at all the lights to see if any are burned out. Could be A marker light if its in the turn signal circuit.
Depending on what type of vehicle it is, it could be the combination flasher relay. 2000 Dodge Caravan, same problem. Replaced DRL/Flasher Relay, problem fixed. Was an expensive dealer only relay...
