Replaced both front bulbs as well as passenger socket.

When hazards are turned on, rears both work/flash with no working front/side hazards.

Also, when turn signal is attempted, turn signal arrow stays illuminated on dash (no flashing), and rear signal stays lit (no flashing), but front signal light does NOT turn on.

Weird thing about this is that both front DRL (daytime running lights work) when interior switch is turned to middle switch and "on".

Would this be both hazard and turn signal flashers are bad? Seems unlikely both are bad. Couldn't find these under the steering column to replace, may have missed them.

 

Is one of your rear lights out? When my turn signals stopped working and the turn signal dash light just stayed lit, it was one of the DRLs burnt out. So when I replaced the DRL bulbs the problem was solved, but you already replaced them. So rear lights?

 

hazard flasher is clipped to the left knee side bolster (you wont see the flasher itself, just the red wiring that goes to it.. its clipped on with a speed clip.)

turn signal flasher is clipped onto the right knee side bolster with a red harness going to it.


again you wont see the actual flashers when looking around, just the wiring harness to each and the clip that holds them onto the backside of each lower dash support.

 

Replaced turn signal flasher, rear lights now flash correctly when turn signal is on, but nothing in the front

 

It sounds like your front lights were not illuminating, which was causing your old thermal turn signal flasher to not flash. I assume you replaced it with an electronic one?

Did the front signals ever illuminate when the hazards were on? If not, you are going to need to do some electrical probing/tracing.

 

No, the front lamps never turn on with either turn signals OR hazards. Rears work fine. Only when I apply power to the brown wire by using the headlamp switch do they illuminate.

Somehow both of the blue power signal wires to each bulb isn't sending signal. Could this be a DRL module problem?

 

The bulbs have two filaments in them. This wire is for your parking lamp filament. The other is for your DRL/Turn Signals.


Yes. But it could also be other things. In order to avoid throwing money at another DRL module and finding out yours was really good - you should really probe the power going in to the module and then the power coming out to confirm the module/relays inside are bad.

 

How do I access the DRL module? Do I need to remove the radio? The dash also? Advice for the easiest way to check these wires would be very helpful.

 

Daytime module is behind the radio.

 

Replaced the DRL module and noticed no change at all. Still no front turn signals or front hazards. DRL lights are also not lit unless headlight switch it turned to middle position, then both front lights turn on.

The car is only activating one of the two dual filaments in the bulb.

Will be using a second DRL module to confirm this in a week, then will go from there. Any other suggestions?

 

Don't do this. It's probably not your issue. The DRL is one piece of a long chain of parts on the circuit for that filament.

Both the hazards and turn signals feed their flashers through the turn signal switch mechanism. You should work backwards through the circuit and trace the wires at the DRL module and see if its even getting power from the flasher. By the same token, you can also trace the same at the flashers.

If power is going to the DRL module, but not coming out, that confirms the module is bad. If there's no power going in, then its something further upstream.
