Nissan Repair: 2000 nissan max se, negative battery, battery terminal

Question
I just turned off my car and what is the buzzing sound(like a faint alarm) that is coming from my engine compartment and is still buzzing after an hour?

Answer
Marisa,

I cannot imagine it doing it for an hour.  I have a 2000 Maxima SE and it does it for a couple of seconds.  SOunds like a relay is stuck.  I would open the hood and remove the fuse/relay cover and touch each relay with my finger until I found the one buzzing and then replace it.  Email me back if you need more.  Also, if you cannot locate it disconnect and then reconnect the negative battery terminal to reset the computer.  It takes only a ten millimeter wrench.
