My 94 altima have a buzzing sound,almost like a fast clicking at the kick pannel on the passinger side.what is the cause? thanks for any help!

It's likely the main relay going beserk (symptom). The cause may be ECM failure.

It could be a blower motor that's starting to wear out.

Answer: the double relay for the head lights was making the noise,as it should,because
Both headlight bulb-socket connecter had over heated to the point where one
Of the female receptors in the sockets was not making proper contact,also a pair of
Wires over heated at the edge of the bulb sockets and was shorting together.
In normal conditions you can hear the relays when you flick the high - beam
On and off.

Thanks for your response.
