I have a 2000 Park Ave. Driving home yesterday, my headlights went out *both low and high beam). Turn lights and tail lights, dash lights all work. The security light stays on. Check bulbs, and fuses all good. What do I look for now?

    The headlights in your car are controlled by the lamp control module. The headlight switch is just an input to that module. The switch doesn't actually switch power to the headlights. There are a total of 7 fuses involved here. You either need a full wiring diagram to check it out or take it to a shop. It's a pretty complicated system

    Check fuses and power to fuses in the blocks with key ON as shown in the 4 jpg's here from the pdf. I'll post all 4 courtesy of bbbind.com and their tsb and electrical diagram service.

    Not an expert, but just looking at what I'd check is power to any of the fuses in figure #3 to see if power is being sent from LCM.
    And do those get power when you use the remote opener (it bypasses the LCM as I read the diagram).

    If you are troubleshooting this for yourself, I can look in my 03 leSabre manual to see what troubleshooting is recommended when this all headlamps fail occurs. I assume the leSabre setup is similar to the PA from 00 if you need help.
