2000 pontiac sunfire headlights won't turn off DRL relay just changed, lights still on. removing fuses shuts them off. high beams will not stay on but flash when switched. DRL indicator light inside flashed when car was on.

Do the high beams work? How about he signal lights? seems to me a light relay (fuse) is gonzo. Basically, there is a light switch that is wired to a fuse/relay. From this fuse relay there is another wire that goes towards the headlights. Seeing both lights are not working chances are the fuse /relay is done for. Cheap and easy fix.

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.

Headlamps
The headlamps are operated when the driver places the headlamp switch in the HEADLAMP position. The LT HDLP and RT HDLP fuse in the IP fuse block, supply battery positive voltage to both the left and right headlamps. The low beam and high beam circuits continue to the headlamp switch. Depending on the position of the dimmer switch, either the low or high beam circuit will now have a path to ground. Ground is provided at G204. The low beam and high beam circuits also provide the body control module (BCM) with both low and high beam inputs. The headlamp switch includes the dimmer and the flash-to-pass switch.
If the headlight switch is left in the HEADLAMP position, the headlights will remain on until turned off or the battery runs dead.
Daytime Running Lamps (DRL)
Any function that turns on the headlights will cancel the daytime running lamps operation. The LT HDLP fuse in the IP fuse block supplies battery positive voltage to the daytime running lamp (DRL) relay coil circuit. The DRL relay switch contacts are connected to the low beam circuit. When the headlamp switch is placed in the OFF position, the BCM will turn on the daytime running lamps. The BCM energizes the DRL relay, closing the switch contacts and grounding the low beam circuit at G204. The DRL illuminate the low beam headlights at a reduced intensity. The DRL will operate when the ignition switch is in the RUN position, the gear selector is not in the PARK position and the parking brake is released. When these conditions have been met the DRL will illuminate.
DRL operation in Manual Transmission equipped vehicles will occur when the ignition switch is in the RUN position, and the parking brake is released.

Probably the dimmer switch . But without testing that would be just a guess . Turnning the headlamps on Any function that turns on the headlights will cancel the daytime running lamps operation..
No ,don't think the DRL relay has anything to do with it .

View wiring diagrams an testing the electrical circuits at the dimmer switch would be the proper way to diagnose .

The daytime running lamps in your 2001 Chevrolet Impala are controlled by the Body Control Module (BCM) Here is a description of how the system works:

The ambient light sensor is a light-sensitive transistor that varies its voltage signal to the Body Control Module (BCM) in response to changes in the outside (ambient) light level. When the BCM receives this signal, the BCM turns ON either the DRL or the headlamp relay for auto headlamp operation. Any function or condition that turns ON the headlamps will cancel the DRL operation.
Thirty seconds after you start the ignition with the headlamp switch set in the OFF position, the DRL will perform one of two actions:

Illuminate the high beam headlights at a reduced intensity in daylight conditions
Illuminate the low beam headlights in low light conditions
The DRL/EXT lamps fuse in the top of the engine fuse block supplies battery positive voltage to both the DRL switch contacts and to the DRL relay coil. When the BCM energizes the DRL relay coil, current flows through the right high beam lamp, to the left hand high beam lamp, to the energized DRL relay switch contacts, to ground G101.
The high beam headlamps are now in series, and split the voltage so that the headlamps illuminate at halt intensity. The DRL operates when the ignition switch is in the RUN position, and the parking brake is not set or the transmission is not in park. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate.

The DRL module may be defective.

First check the R/S headlight fuse in the dash fuse panel (left side), second make sure the R/S low beam headlight bulb filament isn't blown, both these scenarios will do what you are saying. The DRL's work when both low beam lights are in series, thus only 6v going to each bulb at reduced brilliance. The high beam is a totally separate circuit controlled by the multifunction switch. The DRL relay is controlled by the Body Control Module, grounded there, and it will also illuminate the service vehicle soon light. It could also be a bad ground at G204. Its on the steering column support bracket.

this could be a little more simple depending on the lighting outside. quite a few GM's with DRL will turn on the dash lights and tail lights automatically when it gets so dark outside. if it happens when it's completely dark out i would check the switch itself and maybe the relay incase it is sticking

Passenger side high beam element burned out. DRL problem might be the emergency brake suppose to turn off when engaged. Slightly depressed will cause DRL not to work.

Ok look under the bagtterry tray, there is a black box bolted to the body, it is the headlight ground and has a really bad tendency to corode due to the design.

check wiring in front of washer bottle and harness will lead to passanger side follow it open up harness ussually broken wires inside causing dim or no headlights.
