Headlights come on for a
There is actually a possible recall on this issue as it is a known problem with the LCM, or Lights Control Module. Go to the following site:
This is one of the complaints:
HELLO, WE HAVE A 2003 MERCURY GRAND MARQUIS THAT HAS A PROBLEM WITH THE HEAD LIGHTS SHUTTING OFF AT RANDOM TIMES. NOTHING GAVE WARING TO THIS PROBLEM HAPPENING, WE BOUGHT THE CAR USED, AND WAS JUST FINE FOR A YEAR, THEN ALL OF A SUDDEN ONE DAY THE HEADLIGHTS JUST GO OUT. THE FIRST TIME IT HAPPENED WAS ABOUT 6 MONTHS AGO(3-1-10). NOW EVERYTIME IT IS DRIVEN WITH THE HEADLIGHTS ON, IT IS GUARANTEED TO HAPPEN AT LEAST ONCE AND SOMETIMES UP TO 5 TIMES JUST IN 3 MILES OF DRIVING ON MY WIFES WAY HOME FROM WORK. THE ONLY WAY TO GET THE LIGHTS BACK ON AFTER THEY GO OUT IS TO PULL OVER TO THE SIDE OF THE ROAD, SHUT THE CAR OFF, LET SIT FOR A FEW MIN, THEN START AND THEY WORK AGAIN FOR A BIT. THIS IS OVERALL VERY DANGEROUS AND SUPRISING THAT WE HAVE NOT BEEN IN AN ACCIDENT OR RECIEVED A TICKET YET! I AM A ACTIVE MEMBER ON A CROWN VICTORIA FORUM, AND WITH LITTLE SEACHING ON THAT SITE OR GOOGLE YOU WILL SEE TONS OF REPORTS OF THIS BEING A VERY COMMON PROBLEM ON THE 2003-2005 CROWN VICTORIA, GRAND MARQUIS, AND MERCURY MARAUDER. WITH THE HELP OF OTHER MEBERS ON THAT FORUM IT WAS FOUND TO BE A FAULTY LCM(LIGHTING CONTROL MODULE) WHICH HAS A PROBLEM WITH OVERHEATING LIGHTING RELAYS. THE ONLY WAY TO REMEDY THIS PROBLEM IS TO PURCHAS A NEW LCM FOR ANYWHERE BETWEEN $250 AND $600 WITH NO GUARANTEE HOW LONG THAT PART WILL LAST. I ACTUALLY PURCHASED A NEW ONE TODAY. VERY EXPENSIVE FIX JUST FOR THE USE OF HEADLIGHTS, BUT I VALUE MY FAMILIES SAFETY MORE. I WILL BE KEEPING MY OLD LCM TO POSSIBLY HAVE IT REPAIRED FOR WHEN MY NEW PART FAILS AGAIN. THANKS SO MUCH.

How do I remove the two center arm rest on a 2003 mercury grand marquis? I want to replace the covers.
It is a simple but fiddly job. Examine where the arm rest hinges. There will be curved plastic covers. These should just pull up and off. It will reveal a silver pin with a black lock washer fitted on the end furthest from the door.
Using a pair of thin flat bladed screwdrivers and a LOT of patience, you should be able gradually lever the locking washer off the pin. If your careful you should be able to reuse the washer. Once the washer is off, the pin should tap out towards the door. The arm should lift up and out.
you might need to tilt the back of the seat to get better access.

Power steering no assist, has new pump
The average person does not have pressure gauges or the specs for power steering pressure. These readings would show if the power steering pump pressure is correct and then pointing to the problem being inside the rack and pinion unit.
You may be able to take the pump into a hydraulic repair shop and have its performance taken. Although they may not know what rpm your pump needs to be turning for a given pressure performance.
Could be a procedure for air bleeding is special. There was a procedure for Ranger or Chevy S10 type trucks which had strange elevation requirements for fluid to be "burped" with hoses hung higher than pump case. Once air escaped higher elevated hose, system was primed.
Make sure of simple things, like fluid is correct type. Maybe some other Expert will supply more answers.
