The emergency flasher problem is probably the alarm system. Does this happen only when the car is parked and locked? If so, then the alarm system is the prime suspect. But the actual failure won't necessarily be in the alarm system.
Why doesn't the alarm's horn sound? Either it has been disabled or your friend has a missing or blown fuse #16 (blue 15-amp fuse). If the alarm horn worked, then your friend could disable the alarm (put key in driver's door lock and turn to the unlock position) before the flashers kill the battery. The sound of the alarm's horn would also improve your chances of discovering whatever is triggering the alarm system. Do the interior lights and backup lights work? If not, then fuse #16 is blown or missing.
Pulling fuse #22 will disable the hazard lights. I don't know whether removing this will disable the turn signals, but that would be easy to check.
The '95 model year has a different alarm system than my '96. The fuse numbers above might not be correct.
I don't know of any way to access the driver's door lock knob other than removing the door panel. You'll see the problem when you've pulled the panel. I don't know whether it will be something that needs re-attaching or if you'll need parts from a junk yard. A front lock knob falling into the door is not a common problem. This is a mechanical problem that in and of itself can't trigger a false alarm.
The only part inside the driver's door that has anything to do with the alarm system is a microswitch that is located next to the lock cylinder on the door handle. When a key is inserted in the driver's door lock and turned, the microswitch signals the central door lock controller that the door has been either locked or unlocked. The central door lock controller commands the other locks to do likewise, and it also signals the car's anti-theft controller that the car has been locked or unlocked. The central lock controller and anti-theft controller don't "know" if a door fails to lock due to a mechanical problem or failure of an actuator or wiring. Opening a door when the system "thinks" the car is locked will trigger the alarm. If the alarm isn't turned off, then the lights will continue to flash until the battery is drained.
