What causes tail light, park light and dash not to work o n a 94 grand marquis
SOURCE: 2003 mercury grand marquis headlights will cut out
My 2003 Mercury Grand Marquis has the same problem. We found out it was the headlight module located under the dash above the gas pedal. The black box has wire connectors coming out of the back. Hitting the box worked for a little while, then I had to reach in the back and wiggle the wire harness. The dealership wants 500.00 to replace the unit. I consider Highway Robbery! They have installed a faulty piece of equipment on my Luxury car that could easily be life threatening but we know it won't be recalled until someone dies because of it. My husband was able to remove the unit and looked it over it had two circuit boards and he was unable to visibly see any problem or loose wire. He cleaned the connectors and used some electrical terminal grease on the wires, this improved it for a short time. The problem still exsists. I have sat for 30 minutes or more waiting for them to go through the On/Off cycle till they stay on for the 45 minute ride home from work. I have beat the box with my flashlight (maglights handle the abuse, my fingers and nails don't) till it came loose from the brackets that hold it. I leave my car running while pumping gas, short shopping trips and start it 20 or 30 minutes early before leaving for work. It is frustrating and dangerous. If this is the kind of quality in our American made cars it's no wonder they needed a BailOut! The only thing we have found to "fix" it is to find a used part that could possibly have the same problem shortly down the road or pay the theives at the dealership to replace it.

Sounds like the the parking light fuse blew.Under the dash there is a fuse block.you will see fuses there and remove the fuse to see if blown.If so replace with same type fuse.Anymore questions will be glad to help you...
