Ok I have a 97 cherokee and I just heard buzzing from under the hood with the key off turn the key on and it goes away I started unplugging sensors and unplugged the ac pressure switch and it went away but no clue where the buzzing is coming from
Any ideas?

Check to see if its the evap solenoid. They all do that but it usually does it when the engine is running.

It's circled in the picture

Nope not that... Can't really locate the exact location of the buzzing its only when keys off and the ac switch on the ac line is plugged in

Does it sound like its the blower motor running?

No it's not very loud at all

See if the sound seems to come from the drivers side fender. Someone on here had a similar problem and it was the wiper fluid motor sticking on. Just a thought. Other wise you are going to have to get up close and personal and listen real close to track it down. Good Luck and let us know what you find.

It's not doing it anymore but now relays are clicking in the kick panel but every time I get to the fuse box it stops... Go figure

I have a buzzing sound when I turn my 97 off like ten seconds later it buzzes for a second just about every time ...sometimes it does it going down the road. Only for a second...have no idea what it could be
