I have a 2002 pontiac sunfire GT. When I turn on the car everything
seems fine. Then take the car out of park and the DLR's flash and show
the service light on the dash. I also have no low beam headlights.
High beams work fine. I have replaced all headlights and replaced the
DLR relay. Not sure what to do next. Any suggestions?
How do I change the license plate lights for my 2002 Sunfire ??

DLR can be tricky,did you know many cars cut it out for other bad conditions.
1: charge lamp glowing. (it cuts DLR to keep the battery from discharging fast and stalling engine.
2: some even monitor oil pressure. and overheat.
im not looking yours up, lazy today.
but it's in the FSM. all this. see DRL lighting, (canada common)
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.
Fuse panel left side of dash. It's not a typical module it's only a relay. Your instrument cluster has a microprocessor which energizes the relay. In another post someone said there is a resistor behind right headlamp that could be your problem, I haven't as of yet checked the schematics to confirm but sounds right.
