You will probably need an auto electrician.

..

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>?

Hi, I have no idea what a Drl is? If you're looking for the ECU it is usually located behind the center consul. Regards John

DRL, got DRL?
what country. , each country has its own DRL (rules)
or get the FSM?
or if lucky alldata.com,. covers this. it will if USA or Canada.
Canada uses DRL .

hello, it could be ground connection issue, carefully check under the dash at the left side there is a ground bus point, it's a the end of a insulated harness which may be taped to the other harness, all white black wires terminate at the end plug connector, there is a cap on the end, it's a white connector with a bunch of wires going into it, all white/black, remove the cap there may be some corrosion inside, all these wires must be grounded if they are not then make new ground connections to the body. a couple of the wires are grounded and the others get ground from them, however you do it doesn't matter as long as all are grounded. Also take a look at the fuse box inside there may be some wires that look overheated which is a sure sign of bad grounds in the DRL and lighting system,

COULD BE DIMMMER SWITCH .DRL RELAY LOCATED IN FUSE RELAY BOX UNDER THE HOOD IN ENGINE COMPARTMENT.

In Canada it's mandatory to have DRL(Daytime Running Lights). Your Corolla probably has this feature built in. it is a safety thing however I can understand you wanting them off if it's not the law where you live.
In our 1998 Corolla, I use the parking brake all the time - every time I park - and I've noticed the lights do not come on until I release the parking brake after starting the motor. When I park the car, until I shut off the engine, the lights stay on regardless of the parking brake status however, if I shut off the engine and restart with the parking brake on, the lights do not come on.
If you "adjust' the parking brake switch(i.e.: make e-brake light in your dash it stay on all the time) your lights will not go on until you turn them on via the multifunction lever(left side of wheel). This of course negates the benefits of the e-brake light working correctly (warning you that your e-brake is on or that your brake fluid level is low) which in itself is not so safe!
There is a fuse/relay (I think) in the big fusebox under the hood that has a DRL "spot", you might want to check if you can remove it and still turn the lights on manually when you want them on. Alternately, there is a fuse in the interior fuse box(in Canadian models anyway) labelled DRL. When that fuse is out, it seems the lights only turn ob when I turn them on manually.
Hope this helps and God bless,

CHECK HEAD LIGHT CIRCUIT BREAKER AND DRL RELAY OR RELAY.IF ALL IS GOOD.A BAD DIMMER SWITCH OR GROUND WIRE PROBLEMS.

It sounds like your DRL RELAY/Headlight relay. I had this happen with a 2000.

Please rate me if this helps You.

Here is some info that I hope is helpful to you.

This first part is how to disable the DRL
TOYOTA. From the Toyota technical service bulletin EL011-00 Web site for specific models determine where the module is; either the DRL relay or the body ECU, connector number, pin #. Oct 6,2000.

Avalon 1999 DRL relay D4 pin 1
Avalon 2000 body ECU B5 pin 6
Camry S/D 99* DRL relay D6 pin 23
Camry S/D 00* DRL relay D6 pin 10 *twilight sentinel
Camry Solara99/00* DRL relay D6 pin 23
Celica 2000* body ECU B6 pin 17
Corolla 99/00* DRL relay D3 pin 23
ECHO 2000 DRL relay D2 pin 12
4Runner 2000 DRL relay D8 pin 2
Land Cruiser 99/00 DRL relay D8 pin 2
MR2 Spyder 2000 DRL relay D2 pin 12

Sierra 99/00 DRL relay D4 pin 2
Tacoma 2000 DRL relay D8 pin 2
Tundra 2000 DRL relay D7 pin 2
-disconnect battery- Then remove the wire with pin attached and tape to the harness. (consider just cut and tape the wire) -check operation- [except the 2000 MY-Avalon, additionally you need to ground the wire at the module end of the cut wire]


And here is the Headlamp relay part number.

From cheapest/most likely to more expensive: Replace fuse; Replace bulbs; Replace DRL Relay; Check the Ground/Low beam wires for shorts or cuts, Replace Headlight control Switch. Also make sure to check the dimmer relay, its easy to tell if your relay is bad, they will buzz and get hot if defective
