Door ajar reads incorrectly

Door ajar doesn't read correctly. I bought the car from an auction, so I don't have much help. Trying to figure out how to make it stops beeping. Is it a sensor or a fuse?

Horn and windshield washers not working
2008 Mercury Mariner 180000 miles
Two separate issues, but i think theyre both fuse related. Does anyone know what fuse is for specifically the windshield washer fluid pump? The wipers themselves run fine and do their thing as usual but no spray. Ive already run a new fluid line a few months ago before this issue arose so I know the line isnt broken, and its not leaking on the ground when i push the wiper button. So that leads me to believe its either the pump is dead, or the fuse is dead.
For the horn, i have no idea. Its probably either the horn itself or the fuse.

Radiator fans not working
2005 Mercury Mariner 150000 miles
I've checked the fuses. Relays. All fans work when tested. I changed the temperature control valve. I checked the resistor. The blend door is going from defrost to vent to floor just fine but I have no control over the air flow. If it's on its a constant air flow but the 2 radiator fans will not kick on.
Only starts sometimes 
Solved
2005 Mercury Mariner 187000 miles
Been having this issue for a while and it's gradually gotten worse. It won't start at the first key turn, I'll have to jiggle and jiggle to get it to finally start. Dash lights do turn on at axillary, and the radio will pause when I try to start it like normal, but all I get is a single click noise coming from under the radio. I also get a soft electric hum that can be heard in the engine bay, coming from the firewall when the key is turned all the way. I changed starters multiple times, and it'll behave a little better right after but always goes back to the same issue. I've changed the ignition assembly and the switch, and even the switch plug itself. Now it won't start at all, any ideas? I'll try just about anything at this point.

Bluetooth is not connecting to my Motorola Razer 2025
Best answer (according to Devin)
Turns out it was the key reader. (I think it's what it was)
I had to go to the junkyard to get a whole ignition assembly, and it came with a black box ringed around the key part of the ignition. I assumed it was the key reader, took it off and kept mine, but no luck. For shits and giggles i put the junkyard key reader in (I changed the key cylinder to my key) used my key, and it works just fine. It's been over a month now with no problems.

Don't get electrical power to my fuel pump

Don't get electrical power to my fuel pump, where is the fuse

Robert's repair from United States 4 months ago
I had same issue. It's the fuse box it's self! Under rear seat there is a TSB about it. Easiest fix is replace fuse box. I took mine apart and fixed it. But I don't recommend doing it it was a PIA to do. You can get by for a little while by twisting the legs of the relay and fuse just a little , to help make a good connection. But it will only last 75-100miles before it blows or just loses connection again. Good luck
