Turn Signals?!

I have tried nearly everything! I cannot find one solution to my turn signals not working!

Without my headlights on: Left rear blinks fast and front left doesn't work. Right side both front and back operate normally.

With my headlights on: My left rear does work, left front does not. Right side both front and back stay completely solid.

Hazards: Everything blinks except for front left.

In short, front left does not even work at all, and the back left blinks quickly. Right hand operates normally without my headlights on.

Solutions I have tried: Turn signal switch replaced, flasher relay replaced, fuses replaced, ALL bulbs replaced with CORRECT filament and spec requirement.

What else am I missing? please help as much as you can and Thank you in advance!

Check your grounds. These can cause all sorts of problems. Sometimes it's just a matter of removing a screw, clean the connection and put it back.

Thanks for the quick reply!, I have checked the grounds on the steering wheel, right under the dash, and on the driver side a little further back than the headlight. Is there a different one that might be a cause?

It could be rust inside the bulb housing or there may be a wire to the body that is attached with a screw. At the front of a car, rust often gets in small places because of rain on the road. Trace the wires to the socket and maybe use a little bit of dielectric grease to seal misture out and make a better connection.

I would guess (with out seeing the car) the problem(s) are at the lamp clusters or nearby. If you are getting consistant voltage TO each unit then it is one or more earth problems. Inconsistant supply to the units mean damaged wires or (?) corroded plugs and terminals.

I've just changed my wiper blades and now my reverse lights don't work. Should I change my fuel pump relay?

Problem Solved! i cleaned each connection with some electrical cleaner (a couple of times). then some dielectric grease to seal them back up once they were clean. The right hand side still blinks fast, but thats for another day. Small wins! Thanks everyone!
