Default Possible Relay Issue ?

Just a quick one for all the experts on here. When I go to park the car and turn the key off I get a buzzing sound from the fuse block/relay area under the hood and the battery light filckers until the buzzing stops. No other dash lights come on when this occurs. Any help would be greatly appreciated as this is one of the last items on my list. Thanks in advance.

Pop the cover off of the fuse box (4 T-25 Torx screws) and then just feel the relays until you identify the one that is chattering. From your description my guess is that it is one of the overload relays which are the small ones marked with nothing more than J.

Beyond that you may have an issue with the battery line to the fuse box itself.

+1 to what Lee said; according to my manual it's Overload Relay #2 (X+) but couldn't get a definite position on it inside the Central Electrical Unit distribution center (under the hood, drivers side). It's one of the 3 smaller relays in front of the Cruise Control Module and fuel pump relay in there.

If that isn't it, then may have an issue w/electrical portion of ignition switch but would think you would see other issues too if it were that...

Thanks for the info I will try that in the am. Once I find the one that is chattering is it a simple swap and replace or could there be more to this problem ?
