Left fender signal light not working

Post by dexter895 »

My 406 is 1.8 L6A engine. My left side fender indicator not working front and back and right fender lights are okay. Seems no power to the connector any suggestions to fix the issue?

The indicator lamps are fed direct from the ECU so if you have a circuit see which pin it comes out on and trace it from there - or run a new lead.

Do the hazard lights work?

These are a different circuit, and should bypass the Comms unit and feed the bulbs more directly.

If they work with the hazard lights, then it's possibly a Comms unit fault ( if your car is produced after the year 2000 ) or an indicator stalk issue if you have an earlier model.

Unfortunately no. Not working it on hazard mode either. But right side works.

I think there may be a fuse for either sides indicators - I'll see what I can find out...
