Hello, For some time my DRL light flashed (Intermittent) and TODAY, Hui, on all the time with buzz ... I checked my lights and my front right light of day is off ... Should I just change the bulb to turn off the DRL and buzz? Thank you

Check it out. It might have bad connection or burn out.
Good luck

mai

are you in USA.?
are you in Canada with mandatory DRL lighting?
we can not guess that,
DRL car is complex.
DRL has a 20 pin module just for DRL, crazy complex.
the FLASH on DRL grounds the HL directly bypassing DRL relay
so is super important the FLASH test.
There are 2 systems used, the toyota uses hot all time headlights
(via the HL relay and dimmer relay)


I need this?
is it dim on high, yes,
is it dim on low, no.
is it dim , when you push the lever to FLASH.??????
if flash works we know why it fails. see? (paths)
see?
if high beams and FLASH are dim, then DRL relay bad.
(can be other failures., for sure even wires bad)

its just a:
Toyota Corolla. Gen 6 to 8. (in snake skins)
if you have voltmeter this is child's play , really
finding point of voltage drop tells you what is wrong
find a shop with sparks guy? be best or by a meter and learn>?
guessing can take a long long weekend.
is labor time not a matter to you or down time?
ok I pulled up your cars HL schematic.
DRL is super complex
id pull the DRL module and look for burned pins
they love to do that DRL does.
so got DRL
and does FLASH work right>?

Dear Alex,
The problem is in the bulb, or the socket, or the wiring to these.
Whenever a turn signal flashes fast, know that one of the bulbs is not working.
You have already identified the problem as being the front one. Problem could be the hot wire, or the ground wire, or the ground connection to this bulb.
Start by taking a tester to the hot wire, and see if it is receiving electrical impulses when the turn signal is on.
( It probably is, unless the car has been in a wreck and has been improperly repaired.)
Then check the socket or the wires to is and see if the bulb is grounded.
I suspect the ground is defective, and either a new socket or a repair to the ground wire should fix you rights up.
God bless your efforts.

in canada? with DRL?
is the charge (battery Light on running)
nice photo but do name all lights, i see idle is at 800rpm good.
i see check engine light there, top left. so you need to scan PCM
using any scan tool
that is first.

DRL can shut down for other failures one is charge lamp. on.
if charge lamp is on , do not drive far, or it will stall and battery will discharge and be stranded. (till AAA auto tow is called <jumped)

Without testing i would say you have DRL control module problem , But that would just be a guess .
In the night mode, the DRL ambient light sensor senses darkness. Then, the DRL module turns off the front turn lamps and turns on the headlamps through circuit 10. The DRL module also turns on the park, side marker, license, and tail lamps. If the engine should stall with the DRL control module in the night mode, the DRL control module will turn off the headlamps and leave the side marker, park, license and tail lamps on while the engine is being cranked. The headlamp switch operates as usual.
The Daytime Running Lamps (DRL) control module is designed to automatically operate exterior lights depending on outside light conditions. The DRL control module operates in two modes, the day mode and the night mode. In the day mode, the DRL ambient light sensor senses daylight. Then, the DRL control module turns on the front turn lamps (non-flashing) if under the following conditions:
• The ignition switch is on.
• The headlamps switch is in the OFF position.
• The park brake is released.

The brightness of the Vacuum Fluorescent (VF) displays is controlled by two signals: the park lamps on signal (circuit 230) and the VF dimming signal (circuit 308). With the park lamps on, the VF display of the radio, heater, A/C control (with RPO CJ2) and the instrument cluster will dim for nighttime viewing. When the park lamps on signal is not present (park lamps off), the VF displays are at high brightness for daytime viewing. When the park lamps are on, the I/P lamp dimmer switch provides a signal (VF Dimming Signal circuit 308) which controls the brightness of the VF displays when the I/P lamp dimmer switch is adjusted.

Do the Daytime running light's work ?

Thanks Ed

Seldom people share real life fixes for the whole
world to read

the buzzing is the relay driven by the daytime running light module.
the module is under the left side of the dash by the fuse box,but above it and more to the middle.right above your left knee about 8 inches or so.

hi
you will find corrosion in the forward lamp harness that's why your DRL flashes on the dash it's causing a high resistance

There a DRL relay up front that I think is part of your problem. If you go to the front of the car, lay underneath and look up between the rad. and the front bumper, you'll see a set of wires going to a small relay fasten to the bumper. That is the DRL(daytime running lights) Careful removing it and have it replace, can get it at a local part store. After repaceing it, see what problems you have now.
Maybe high beams work now but no low beams? If so, you need to check the blue wire for a open connection. This blue wire controls the low beams. Please take the time and get a manual at your local auto store so you can see the wiring on the lights, this will help you pin point the blue wire.
Just keep checking the blue wire for conutity, through out the blue wire, you'll have to open up the casing cover over the wires to see where they leaded. Hope you find it!

The problem with the DRL issue describd in the above posts is the DRl module(it needs to be replaced). The buzzing relay and intermittent on/off of passenger side DRl are indicators that the module needs to be replaced.
