Check fuses, both switches and wires.

This is for the 4.6L motor...I'll post for the 5.0L and 5.8L....you didn't post your engine size so please pick the applicable motor:

4.6L Engine
CAUTION Fuel injection systems remain under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

1. If equipped with air suspension, the air suspension switch, located on the right-hand side of the luggage compartment, must be turned to the OFF position before raising the vehicle.
   
2. Disconnect the negative battery cable.
   
3. Drain the engine cooling system.
   
4. Relieve the fuel system pressure as follows:
   
   1. Remove the fuel tank fill cap to relieve the pressure in the fuel tank.
      
   2. Remove the cap from the Schrader valve located on the fuel injection supply manifold.
      
   3. Attach Fuel Pressure Gauge T80L-9974-B or equivalent, to the Schrader valve and drain the fuel through the drain tube into a suitable container.
      
   4. After the fuel system pressure is relieved, remove the fuel pressure gauge and install the cap on the Schrader valve. Secure the fuel tank fill cap.
      
5. Disconnect the fuel supply and return lines.
   
6. Remove the windshield wiper governor (module).
   
7. Remove the engine air cleaner outlet tube.
   
8. Release the drive belt tensioner and remove the accessory drive belt.
   
9. Tag and disconnect the ignition wires from the spark plugs. Disconnect the ignition wire brackets from the cylinder head cover studs.
   
10. Disconnect the wiring from both ignition coils and the Camshaft Position (CMP) sensor. Tag and disconnect all ignition wires from both ignition coils. Remove 2 bolts retaining the ignition wire bracket to the ignition coil brackets and remove the ignition wire assembly.
    
11. Disconnect the alternator wiring harness from the junction block at the fender apron and alternator. Remove the bolts retaining the alternator brace to the intake manifold and the alternator to the cylinder block and remove the alternator.
    
12. Raise and safely support the vehicle.
    
13. Disconnect the oil pressure sensor and power steering control valve actuator wiring and position the wiring harness out of the way.
    
14. Disconnect the EGR valve to exhaust manifold tube from the right-hand exhaust manifold.
    
15. Lower the vehicle.
    
16. Remove and detach the engine/transmission harness connector from the retaining bracket on the power brake booster.
    
17. Detach the A/C compressor clutch, Crankshaft Position (CKP) sensor and the canister purge solenoid wiring connectors.
    
18. Remove the PCV valve from the cylinder head cover and disconnect the canister purge vent hose from the PCV valve.
    
19. Disconnect the accelerator and cruise control cables from the throttle body. Remove the accelerator cable bracket from the intake manifold and position out of the way.
    
20. Disconnect the vacuum hose from the throttle body adapter port.
    
21. Disconnect both Heated Oxygen Sensors (HO2S) and the heater water hose.
    
22. Remove 2 bolts retaining the thermostat housing to the intake manifold and position the upper hose and thermostat housing out of the way.
    

The 2 thermostat housing bolts are also used to retain the intake manifold.

1. Remove 9 bolts retaining the intake manifold to the cylinder heads and remove the intake manifold. Remove and discard the gaskets.
   
2. If replacing the intake manifold, swap over the necessary parts.
   

To install:

1. Clean all gasket mating surfaces.
   
2. Position new intake manifold gaskets on the cylinder heads. Make sure the alignment tabs on the gaskets are aligned with the holes in the cylinder heads.
   
3. Install the intake manifold and 9 retaining bolts. Hand tighten the right-rear bolt (viewed from the front of the engine) before final tightening, then torque the bolts, in sequence, to 15-22 ft. lbs. (20-30 Nm).
   
4. Inspect and if necessary, replace the O-ring seal on the thermostat housing. Position the housing and upper hose and install 2 retaining bolts. Torque to 15-22 ft. lbs. (20-30 Nm).
   
5. Reconnect the heater water hose.
   
6. Reconnect both HO2S wiring connectors.
   
7. Reconnect the vacuum hose to the throttle body adapter vacuum port.
   
8. Install the accelerator cable bracket on the intake manifold and connect the accelerator and cruise control cables to the throttle body.
   
9. Install the PCV valve in the cylinder head cover and connect the canister purge solenoid vent hose. Reconnect the A/C compressor clutch, CKP sensor and canister purge solenoid wiring connectors.
   
10. Reconnect the engine/transmission harness connector. Install the connector on the retaining bracket on the power brake booster.
    
11. Raise and safely support the vehicle.
    
12. Reconnect the EGR valve to exhaust manifold tube to the right-hand exhaust manifold. Torque the tube nut to 26-33 ft. lbs. (35-45 Nm).
    
13. Reconnect the power steering control valve actuator and the oil pressure sensor wiring connectors.
    
14. Lower the vehicle.
    
15. Position the alternator and install 2 retaining bolts. Torque to 15-22 ft. lbs. (20-30 Nm). Install 2 bolts retaining the alternator brace to the intake manifold and torque to 71-106 inch lbs. (8-12 Nm).
    
16. Reconnect the alternator wiring harness to the alternator, right-hand fender apron and junction block.
    
17. Position the ignition wire assembly on the engine and install 2 bolts retaining the ignition wire bracket to the ignition coil brackets. Torque the bolts to 71-106 inch lbs. (8-12 Nm).
    
18. Reconnect the ignition wires to the ignition coils in their proper positions. Reconnect the ignition wires to the spark plugs.
    
19. Reconnect the ignition wire brackets on the cylinder head cover studs. Reconnect the wiring connectors to both ignition coils and the CMP sensor.

4.6L engine intake manifold torque sequence—1996-98 Models

From the 1997 Mercury Grand Marquis 4.6L SFI 8cyl repair manual, the Flasher is located behind left side of instrument panel. The turn signal and emergency flashers are attached to the interior fuse panel. They are replaced in the same manner as the fuses and circuit breakers.

Hope helps (remember rated this).

The problem is most likely the contact ribbon under the steering wheel, it has a broken printed circuit ribbon to the horn button, it is referred to as the "Clock Spring Contact Drum"

What kind of vehicle is it year ,make ,model please

You need to replace the window regulator.

When you say it wont start, it wont crank even a little bit? any clicking? i would look for an issue with the starter if the wires are getting hot, you could have a corroded ground wire which would cause a backup of electricity making the wire hot(simply put)

You may have a bad connection where the battery grounds to the frame and/or engine. Check the cable running from the negative battery post to where it bolts to the car. It should be clean and very tight - no corrosion. If you can see the connection, watch it while someone tries to engage the starter. See if it sparks, or starts to smoke or glow a dull red. If so, the connection needs to be cleaned up very well.

use flex joints and extension bars to get back to a place where you can use a ratchet or bar

there should be a 'legend' on fuse box cover identifying locations specific to your model.blown fuses are readily identified when removed & inspected. after market radios usually have an 'inline' fuse on the power supply wire as well.

Could be a leaking hear core or hose that goes into the core.

the lock isnt turning the back part which is the contact switch,use a screwdriver to turn it off or disconnect the battery. I think the problem lies in the barrel is got a piece broken that goes from the barrel to the contact switch .Without seeing it myself i couldnt tell you whats wrong or why the barrel has come out but their is a small hole in the case where you can push in to remove the barrel but in all honesty ask a local mechanic to have a look for you as this mat be beyond the average hme mechanic to sort out also their is a security reader that reads the chipped key callled a transponder so a local mechanic who knows what hes doing is your best best .Sorry if this appears a negative answer but as stated i would need vehicle in front of me to diagnose the correct repair.

When you say the fuel pump relay is good did you test for power to the relay circuit ?

If sound comes from under the dash, it might be an hvac actuator that is having a problem? Sometimes you can put your hand on it and feel the vibration? Sometimes with a relay, you can do the same thing.
