I have 1991 honda accord and the door senors show

for the brake lamp stays on.... try replace all the brake lightbulbs as maybe one of the bulbs is about to blow which resulted in higher resistance.
for door ajar stays on.... check all doors, bonnet switch. either one of them is on close loop.

i think?
you meant?
My A/T tranny shift lever is stuck in park. right?
and sure, if the brake lamps are dead, that is normal
fix lamps now. or brake switch is bad, or fuse blown.
always check fuses FIRST. always.
or if in great desperation, (can happen)
the operators guide in the glove box told you what to do....
sure lost.
here is your missing guide
http://justgivemethedamnmanual.com/honda/honda-accord-coupe-owners-manuals/

read the page on A/T park lock emergancy bypass.
takes 1min. to do.

no one? any ASE mech can, for sure, and blindfolded.
the reason you can;t is because you dont have a $20 voltmeter.
btw 2 , some cars have hacking to this circuit, trailers attached?
collision damage.
and yes, wires to fail, not just rare at all.

lets pay a game, you go to walfart buy DMM
and go home, and set it to 20vdc range.
and measure voltage to the brake switch, its 12v, may need key on to do that.
then step on brake, the output of the switch goes to;;;
examples. input to switch 12v brake on, all the time. braking or not.
step on brake reads..
1: 0v, switch bad, or gross short close by.
2: 1 to 8v> reads too low, short in harness or 1 lamp shorted.
3: 12v, (battery is at 12.5 ) normal wire drop is 0.5v on all cars.
if 12v here, then wires are cut, to the lamps or all lamps are burned open. (not in yourcase, but to be accurate)
now at this moment you know what is bad.
if the input to the switch is not 12v that means you blew the fuse again,

the volt meter will not lie to you, and will show you the drop voltages.
a normal car will have 12v to each lamp. if not there is DROP.
called voltage drop.
do the tests, post the voltages and we can find it fast.

also skipping looking at both rear under finders for hacks is bad.
look, and behind the Tail lamp assemblies for hacks, or collision damage.

You can try to replace all the brake lamp bulbs as sometimes eventhough all bulbs are working but one of them is about to blow and give high resistance. That's why the brake lamp lights up.

Brake light bulb is fused, check all bulbs. Tail light, brake light.

most of the time it means the parking brake is not off fully.

look further,it may be that internally something isnt working,or is the external latch connected to the pillar not right,,is the door actually unlocking,eg;from the inside or outside does it work O.K??

have your brakes checked. the seat belt may be covered under warranty, ck with the dealer. I worked at a Honda Dealer in the 80's and I think their seat belts were covered for the life of the car. I could be wrong

Alternator not charging by if all lamps are lit

-the problem is the switch is connecting when you hit a bump or something closing the switch the door or trunk lamp is only a switch and when the switch is completed or close then the light goes on and if it opens the light goes off
