Drl stopped working on my 1999 lx470. checked fuses they are good. Noticed there is no power to those fuses. can it be a relay? if so then why does everything else work?

Does the front park lights work and does the vehicle have Daytime Running Lights? If it doesn't have DRL make sure fuse 53 (10A) is good and has power. The stop lamps and tail lamps use the same B61 ground. The ground should be ok. If the fuse is good and has power then there is a possibility there is an open in the circuit between the fuse and the E117 connector or a disconnect at the connector. If it does have DRL it is possible the DRL relay does not have power (fuse 59 in the IPDM 10A) or it is faulty or the IPDM is not grounding it.

which one?
what are the symptoms. must i help blind?
there are these parts. (maybe)
head lights.
relay(s) module.
DRL module.
wires and connectors
HL switch
HL Fuses.

the FSM covers this ,so does alldata.com (log in?)
i have a 04, and the relay are on cab left fuse box.
mine has DRL, dayligh running lights option (i hate it)
does yours. its very much different, and DRL is way less reliable.
the DRLs love to MELT on Suzuki cars. (trash)
I'lll ASSume its non DRL here i the drawing,
got a voltmeter?we can find true cause in minute work.


here is the schematic
small photo sucks, here at fixyah, but can send a link
to real, if serious. most are not. here.
as you can see there is just 1 relay. no DRL.
the engine size also dictates the fuse box size.
as does other major options. but if you open
your operators guide, it will have the fuse blow drawing there
and the relay shown.
the DRL module is just to right of steering shaft behind dash.
the Relays are just above left toe (USA CARS) and at Fuse box
(the boxes vary , so get the operators guide for your car, matching your engine. mines H25, below is simple non DRL.
the fsm covers it 100% get that.

sounds like a fuse or relay ,have you checked the fuse box drivers side lower dash for headlight fuse(s) also in engine bay there is another fuse box with relays ,list will be on the cover ,i'd start there as power is going to bulb on one circuit , other than that the switch may not be working fully

Short term, pull the drl fuse, see if lights go out. Check to see if headlamps will still work with drl fuse removed? If they still work, don't worry about it.
Just between me and you, I've never cared for drl.
I can give you wiring diagrams if you want?

if replacing the high beam bulbs do not fix the DRL issue ,see my tip under 2001 to 2005 civic daytime module repair.The accord you have has the same module.

The fuses that protect your headlamp circuits are Fuse Numbers [4] (Left High Beam), [5] (Right High Beam) [6] (Left Low Beam) and [7] (Right Low Beam).
Fuse 4 is a 10 Amp fuse
Fuse 5 is a 10 Amp fuse
Fuse 6 is a 20 Amp fuse
Fuse 7 is a 15 Amp fuse
All are located in the Power Distribution Center in the engine compartment.

The difference between a 1999 Chrysler Town & Country with DRL and WITHOUT DRL is that one has a DRL module and the other does not. The headlmps themselves are wired exactly the same.

To make yours work, you would have to add the DRL module and reprogram your Body Control Module (BCM) to accept the DRL module. Doing it any other way would probably result in the BCM setting fault codes and possibly even causing malfunctions in other non-headlamp-related circuits.

Don't forget to check the Relays.... Black boxes associated with the fuses... Also there are usually two fuse blocks ONE inside of the car on the drivers side: Under the dash, or on the side of it. TWO is under the hood in the engine compartment area either on the firewall or on one of the fenders usually close to, same side as the battery.

If it is anything like my 04 GMC Sierra, there is a relay panel under the hood. In that underhood box where you found the fuses, there are also relays. They pop out (the diagram is on the lid of the box). After the GMC hit 200k, the relays started going out. The high beams are on a relay, the lowbeams are on a different one. You can pop one out and replace it with the horn or foglight relay if you want to check it out. I am betting that the DRL bulb just happened to go at the same time. Mine go out regularly..I would say around every 10-15k miles. I don't know if this helps, it is just something that I have run across with a similar vehicle.

Does your car have daytime running lights? It may be the drl module. The relays are part of the IPDM (intelligent power distrubution module) and are not serviceable. If the drl module is faulty the symptoms are, no drl, and one or more lights not working. Usually not grounding within the drl module.
