da ding ding dont ding

anyone knowz what is responsible for the beeping sound in the 90 integra when u get out of the car and leave te light on... mine dont work on the driver side .. the roof light dont come and it doesnt sound if u get out and dont turn the light off ... but the passesger side works fine .. the automotic seat belt works fine so i dont think it is that little switch in the door jam ... but i could be wrong .. :confused:

check the fuse. don't know the exact number, but look in ur manual. it should be there.
