2006 Chrysler Sebring just had battery changed now i have no headlights or fog lights, but I do have parking lights and tail lights. any thoughts

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.

2006 chrysler sebring I also have 2008 Chrysler Pacifica and I had purchased its manual from online store reliable-store.com. Here's the site link
I am sure they will help you

it is your bcm which is your body control module

sounds like the brake light switch that is on the brake pedal

The relay has nothing to do with the tail lights, but replacing the switch sounds like a good idea. There's a nut holding it in place, see http://www.skandix.de/en/spare-parts/electrics/switches/switch-headlight/1027524/ to get an idea of the construction. And the price. This is not worth fiddling about unreliable workarounds...
In addition, if fuses 15 and/or 16 burn frequently there might be a problem with the tail light cabling.

Good luck

brake light switch may need to be adjusted or replaced
Cheers Rob.

LOOK ON SWITCH TO TURN ON HEADLIGHTS..IF THEY ARE FACTORY FOG LAMPS,PULL OUT ON END OF HEADLIGHT SWITCH..IF NOT FACTORY,CHECK FOR A SEPERATE SWITCH,OR THEY MAY NOT BE WIRED UP

check switch continuity and relay , might not have a fuse , also the fog lights on any car will shut of when headlights are switched to high beam

Behind the headlight you should see a eletrical wires running to the headlight section. There will be a 2 inch round plastic ring. You grap the back of the bulb and turn it to the right which will release the bulb and the socket. You pull out the bulb and replace it the same way. If this doesnt help then get back to me.

The roatating knob that turns on the headlight pulls out to turn on the fog lights, but only pulls out when the headlights are on,
