Don't start below freezing
check it has the correct viscosity oil in the engine, check the battery is in good condition and then any cold start devices
Air suspension is not working
It just happened to me. I took it to a spring shop and had the air bags replaced with coil springs. It is an identical fit from a Crown Vic and only cost $200.00 total! Too much can go wrong with other parts of the air suspension. The ride is the same.
Auxiliary power outlet doesn't work. Checked the fuses everything seems fine
Although you did not specify how you checked the fuses, I surmise you used either a light tester at the fuse panel or an ohm meter, since visual inspections can be deceiving.
I will safely guess that this auxiliary power outlet works whether the ignition key is turned on or off and that you checked for voltage while the ignition key was turned in any position, just the same...
In as much as there is a fuse box in the cabin compartment of the car, there is a power distribution panel inside the engine compartment that contains fuses too...and they were checked(?)
I would check for continuity between the pin (base of the socket) and the ground (walls of the socket.) If there is no continuity, most likely the fusible link built-in to the socket- melted as a result of high current draw.
A fusible link is placed within the circuit of the socket itself, for wiring protection, so that you don't damage any other component that's wired on the same circuit (and/or cause a fire in the wiring harness due to the high current draw.)...and you don't necessarily have to blow a fuse at the box or at the distribution panel to have a power loss at the auxiliary power outlet's socket.
Other possibilities to consider, the wires to the socket could have oxidized, frayed; loosened; broke or become disconnected; or the socket itself could be damaged and gone bad (i.e- the fusible link.)
You can also have a break in the wires somewhere else down the line and not at the outlet's socket itself.
Were is location to speed sencer on 2003 grand marquis
If it is not on your tail shaft driver side, this picture will give u a good Idea. When you go buy it if it is a long one it goes on your tail shaft. Above the arrow you see a hookup easy to install. If it has a bend then follow the arrow. Good luck.
