I have a buzzer that sounds shortly after starting car. No lights on dash light up. Have replace one oil pressure switch. What else could it be? Oil level is fine. Temperature gauge also not working.

Welcome to 2CarPros.

When you say buzzer, do you mean the same noise as when a door is open? Is the top secure? Is the sound continuous? Can you record it and upload it for me to hear?

Let me know.

It does not have a door sensor or roof sensor that I know of. Yes, it is continuous. When first started it is not there, then in about five minutes it starts. It is behind the instrument cluster somewhere. I will try to record it but I am not very tech savvy.

The door should have an indicator that it's left open or at least the key is in the ignition. And no light is on? Try your best to record it. Most people just use their smart phones to record.

Let me know.
