#237 of 246 autolamp relay
Feb 19, 2013 (8:50 pm)
I found the problem with my lights,it was the autoheadlamp relay.It was mounted just to the right of the wiper control module and come to find out it was clicking when the lights flickered on and off.So I unplugged it and problem solved..no auto lights but who cares..,,,this is on my 94 Grand Marquis GS ..

Problem not fixed,my lights are still going out,i guess i'm going to re-wire from switch back as far as i can go.

Did you ever change the switch?

No, I never changed it yet,i left the autolamp relay out thought that was the problem,no luck so i'm replacing it today.So it could be the switch then?

Dangnabbed if I know I consider it likely though. As you don't have a LCM and iirc you don't have a relay driven headlight system - and your harness had damage - it's what I would do (as Shiftright mentioned), with a fair feeling of confidence.
Panthers had a headlight switch problem for this very reason until they came factory with a relay system. You may find your headlights are brighter with the new switch too.
If you're a bit handy and you're planning on keeping it you can also fix the problem pretty much permanently by converting to a relay system, as I have with my 85 Town Car. It did make the headlights noticably brighter too.

Got a new battery,lights work fine now.

Well the new Battery didnt fix the problem,but had an effect on the problem for the lights all but quit shutting off until today.It was raining tonight and when i ran my wipers,the lights started acting up just like before.

#246 of 246 92 Crown Vic LX - no instrument panel/marker lights

Had to get up under the dash to fix loose column shifter. Tightened up two bolts. Then somehow found out the next night that I had no dashboard lights, radio/AC cluster or tail lights. Turn signal lights work, as do high beam and turn indicator lights on dash work. Checked the fuses both under the dash and under the hood.
Was wondering if it's just the light switch or could I have pinched a wire when tightening those two bolts?
Someone thought there might be a lighting control module or something called an autolamp dual coil relay. Doe anyone know anything about this?
