2 quirky problems.
 

The first problem is that as of last night my seat belt warning buzzer won't go off. Is there anyway to disconnect it?

Second problem.....my interior light (Targa) only lights up when the passenger door is open, not the drivers door. Any help on these 2 irritating problems is GREATLY appreciated. Thank you.

On the light issue, check to see that the door switch, located in the front jamb between the hinges, is operating correctly and is grounding properly. The boots can rip. water gets in and the contacts can oxidise.

There is a relay behind the fuel level gauge that can be removed to silence the buzzer.

For the light, make sure the light fixture is in the correct position. It rocks into 3 positions. One is so it activates when the door opens. Check the light bulb itself, the wiring, and the fuse.
