while driving my 90 gxl ive heard a buzzer sound a couple times. It sounds just like the rev buzzer but it is a really short beep. and no im not at high revs.

the cars auto.

 

Power steering computer. If it beeps a couple times then goes away, it the power steering computer.

 

why does it beep?

 

Beeps are power steering computer.

but if it is a buzzer then it is either over rev, low oil, or low water (or air bubbles in the water).

 

Only buzz sound I have heard is the low coolant buzzer.

 

My low coolant buzzer went off yesterday for no reason (checked coolant, it was normal) damn near scared me shitless, i was in the middle of a turn and the car started buzzing, first thing that came to mind was "@#$?!?"
