I have a 83 monte carlo and I pull my lights on knob and all my lights come on;tail, tag, park, markers, but not my headlights....my turn signal lever( to turn on my brights) if I pull it the normal headlights come on....why??

What about them ? What front lights ? Headlamps , park lamps, marker lamps ? They don't work ?

Exterior Lamps
The exterior lighting system consist of the following lamps:
• The Headlamps
• The Daytime Running Lamps (DRL)
• The Clearance Lamps (Y92 roof rack only)
• The Cornering Lamps
• The Front Fog Lamps
• The Rear Fog Lamps (Export)
• The Park, Tail and Marker Lamps
• The Turn Signal Lamps
• The Stop Lamps
• The Backup Lamps

Park, Tail, Marker, License, and Clearance Lamps
The park, tail, marker, license, and clearance (Y92 only) lamps are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The I/P BATT fuse in the engine wiring harness junction block supplies battery positive voltage to both the park lamp relay switch contacts and the park lamp coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the park lamps are turned on, the BCM energizes the park lamp relay. Current flow is from the park lamp relay to the individual park lamp circuit fuses and to their respective park, tail, marker, and license lamps. The front park and marker lamps are grounded at G107 and G103. The tail lamps are grounded at G401 and G402. The license lamps are grounded at G401. When equipped with the Y92 roof rack option, the clearance lamps are grounded at G302. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, the park, tail, marker, license, and clearance lamps will remain on until turned off or the battery runs dead.
The T PARK fuse in the rear fuse-relay block supplies battery positive voltage to a separate park lamp circuit connected to the trailer wiring harness.

sounds like a shorted tail light or maybe 4 way flasher has ground problem ,what happends when you put on 4 ways and step on brakes ????

I have the same exact problem on my '95 Monte. I was told to replace my Headlight Switch which is the unit to the left of the steering wheel that controls the dimmer, parking lights and headlights. Headlight switch goes for about $70 and supposed to take about 1/2 hr to swap out.

Park, Tail, Marker Lamps, and License
The park, tail and marker lamps, including the license lamps, turn on when the headlamp switch is placed in either the PARK or the HEAD position, or anytime the headlamps are requested. The RT I/P #1 fuse in the RH I/P fuse block supplies battery positive voltage to both the park lamp relay switch contacts and to the park lamp relay coil circuit. The park lamp relay coil is controlled by the body control module (BCM). When the headlamp switch is placed in the PARK position, the BCM energizes the park lamp relay coil control circuit.
Current flows from the park lamp relay switch to both front and rear park lamp fuses and to their respective park/tail lamps. The front park lamps are grounded at G101. The rear park lamps are grounded at G302. The license plate lamps are a part of the rear park lamp circuit and are grounded at G302. The inadvertent power control feature prevents the park lamps from remaining on more than 10 minutes if left on. If the park lamps are turned on after the ignition switch has been turned OFF, or is in the ACCY position, they will remain on until turned off or until the battery runs dead.

Did you the REAR PARK LP fuse 15 amp in the right insturment panel fuse box.

on an 83 its either fuses,bad wiring or maybe even bulbs. oh yeah the sockets could be bad. one will cause the other to not work.

I would recommend finding the fuse and check it first, then find and check the headlight relay, one of these must be faulty. Good luck and Happy New Year!

If you'vegot headlights, brake lights and blinkers, but no park or tail lights and no dash lights, it's time to replace the headlight switch. Hopethis helps.

inside your trunk you must pull back carpet exposing bolts holding tailight in. remove those bolts and pull tailight out. you can then remove sockets by turning counter clockwise. replace appropriate bulb

Probably the headlight switch. To remove the pull out part of the switch, there is a button on the switch that you push while pulling on the knob. The nut that holds the switch to the dashboard can then be turned counter clockwise to remove. Drop the switch and unplug the wiring.
