Those are your day time running lights the only way toget them to turn off is to click your parking brake one notch. although i wouldn't reccommend you drive around with your ebrake on. general motors designed those head light like that for safty reasons.

[hi

this may be there is a short circuiting on the switch which might have by passed the switch so the light is always on. this may be in two locations one in
1.the switch itself and other may in the passage of the wire to the swithc.so try changing the switch and check the problem stil presists,

2.if the problem presists then there is problem with the wire connecting to the switch. so you hav eto trace full wire connection from the battery to the switch.

if my answer was useful to you please vote for me.

How can the lights be disabled that stay on all the time ?


Have you tried replacing the headlamp power relay in the underhood fuse/relay box ?
Headlights Circuit Description
Voltage to the headlamp switch is available at all times from the HDLP SW fuse 7 through CKT 1940 (ORN). When the headlamp switch is turned to the HDLP position, the headlamp power relay coil is energized through CKT 352 (WHT). A signal is also sent to the body control module (BCM) that the headlamp switch is ON. When the headlamp switch is in the AUTO or PARK position, the ambient light sensor (located in the right speaker grill) senses either daylight or darkness and sends the signal to the BCM. When the Ambient Light Sensor detects a dark condition, the BCM produces a signal that will energize the headlamp power relay through CKT 352. The relay coil is grounded through terminal F7 connector 2 of the UBEC to CKT 350 (BLK) to G102. When the headlamp power relay is energized the relay supplies power to the LT HDLP and RT HDLP fuses. The RH low beam headlamp receives current through CKT 198 (DK BLU) from the RT HDLP fuse. The LH low beam headlamp receives current through CKT 712 (YEL/BLK) from the LT HDLP fuse. Both headlamp low beam bulbs are grounded by CKT 524 (PPL) through the UBEC to the multifunction switch (low position) contacts through CKT 10 (YEL) to the headlamp grounding relay in the body relay block through the normally closed contacts to CKT 1850 (BLK) to G200.

Headlights stay on, ignition turned off


If you turn car off and remove key from ignition, th? headlights will stay on until you open the driver side door, its part of an auto on headlight system. you can leave your selector light switch on the headlight position or on the daylight lamp relay (DRL) position. and open the driver side door and the lights will go out and not stay on. so it saves running your battery down. That feature is only on SLE trim line on the Solara.

The headlight stay on all the time, either daytime running lights or all lights. The car has a sensor bulb in the dash. If you pull the headlight switch on and then push off, they still stay on. Trying...


This sounds like how the headlights on this vehicle are designed to operate. They can be manually turned on if in DRL mode. Setting the park brake before turning the ignition on should keep them from lighting, otherwise they are always on. The light sensor switches between lowbeam and daytime running light modes.
