Let the handy man at it,
There could be many reasons why the 1993 Grand Marquis make noises when the doors lock. The wiring could be off, or the motor could be going out.
maybe it sensed that it wasnt as dark as it was an hour ago, there are two ways to turn your head lights on in a mercury grand marquis, at least my 92-93. you can pull the headlight switch which makes them stay on, or you can turn the small nob button to your right to do the light sense headlights. hope this helpsAnswerOverload in system? Circuit breaker cycling?
The reset button on the fuel pump inertia switch should be DOWN ( if the button has popped up , then no power is going to the electric fuel pump )
On my '93, there is no consumer serviceable port. I think the recharge has to be done by a technician.
MY 93 GRAN MARQIS EGR VALVE IS LOCATED AT THE VERY REAR OF THE ENGINE BELOW THE INTAKE MANIFOLD AND A LITTLE TO THE RIGHT SIDE OF THE CENTER OF THE ENGINE AS VIEWED FROM THE RIGHT-FRONT FENDER. IT IS A LITTLE DIFFICULT TO SEE BECAUSE THERE IS STUFF OVER THE TOP OF IT. I DON'T KNOW IF THE 98 IS SIMILARLY SITUATED, BUT THAT WOULD BE A GOOD STARTING POINT.
My 93 Mercury's windows are off track. They stay on track until I manually push them up and they go off track. I have been told that you have to drill out the rivets that keep the window on track, adjust them, then replace the rivets with a bolt and nut.Could this be right?John
The colors are irrelevant, just use any 50/50 mix & you will be ok.
