02 protege headlight on warning disabled
 

Help I have to leave house when it is dark and get to school when its light. My headlight-on warning had been disabled by previous owner and since I have needed 3 jumps this year so far, I would like to turn it back on. Any one know how to do this?

are you talking about the headlight symbol inside the gauge cluster is not glowing? honestly most likely the light bulb just burned out take out your gauge cluster and check it out, if the light but is all black thats the problem. cause i really don't even know if there is a way you can disable that feature without cutting the wire or something.

Not the issue
 

No I mean the ding that comes on when you open the door, that reminds you the lights are on. The ding works when you open the passenger door, but not the drivers side

hmm well it has to be the sensor in the door then thats the problem put your key in the ignition and open the door to see if the dinging sound works if not then maybe the sensor is no good
