It appears to be a known issue. You need a good auto electrician.

if not fitted with a start safety feature where brake pedal has to be depressed before start and shift

fault in the shift cables connections adjustment
or bushes of shift stick or button release stopped out of any gear

stuck mechanical park locking pall inside the transmission

transfer case or drive train issue
broken engine or gearbox mounts

if you are operating the motor without a load on it ie hooked up the the gear drive for the seat, it could seem good. Look for damaged wiring near the parking brake and under the door sill plate

relay may be under the hood.or behind glovebox.

sounds as if your weatherstrips are leaking try spraying water from a hose around the door jams, then look around inside the car door (open) for evidence of water getting past the weatherstrips, where you find water in the car- that's where the air is getting in

You need to remove the trans pan to inspect the parking pawl and rod. Hopefully you can adjust or repair with trans in your vehicle.

Also don't assume your cable etc is okey. You don't know that. You may be able to adjust it and be okey.

disconnect battery leads and reconnect them to try to reset horn and locks

do you use your ebrake? did you use your e brake after it had't been used for a long time. sounds like the e brake might not be released all the way.

Disconnect as many of the door switch wiring plugs, and wiring plugs for the seats that you can. Then, drop in a fuse. If it blows, you probably have a wiring issue, not a switch issue. If it doesn't blow immediately, reconnect the doors, and seats one at a time till the fuse does blow. Once it does, you've isolated your problem to a smaller area, and can replace / rewire that component.

If you've disconnected everything, and the fuse still blows, you probably have a wiring issue that will need to be traced. You will need a multimeter that can read ohms. You'll need to isolate different parts of the circuit (probably by unplugging and or cutting a wire in that circuit unfortunately) then use the multimeter to test the ohms from that part of the circuit to NON voltage side of the fuse holder. (If you try to test ohms on a hot circuit you will likely fry your multimeter!). If the meter reads low ohms, there is your short. High ohms (infinity) means there is no circuit, and there is no short. When you hit on something of low ohms, you've isolated the problem to a smaller area, and can keep tracing that wiring back to the fuse box to find your short.

Good Luck.

Some of the Escorts do not have central locking. If the keys open both front doors, the hatch and fit the ignition then I would not worry too much about it. You may find that you also have a hatch release catch at the side of the drivers seat also. I trust this information helps you.
