(95 z28) Clicking noise under the dash when car is shut off?(sounds like turn signal)

So a co-worker of mine got z28 and he has a few little things. One of them is when we shut it off, there is a clicking noise under the dash, it sounds alot like turn signal is on, but its straight and forward. Seems like it shuts off later on(we go back and its still not doing it)

Just checking out here if its a common problem, I have never really heard of it before.

had similar problem with my 96z....ended up being a loose conection on the BCM...to the point the wire contact was burned.

worth a look-see
