Clicking Noise in dash

[GLT]

ok so I just bought a 94 F350 cc dually with a 7.3 turbo with 203000 miles and I have noticed that when I am driving or the key is turned back to the accessory position I here a clicking noise in the dash behind the glove box it drops my voltage gauge to around 10volts also it will jump my temp, fuel and oil gauges and cause a little static in the radio but it only last a sec however it does this every 5-10 secs I removed the glove box and tracked down the noise maker it is a little black box but I don't know what it is or if something else is causing the box to click can u guys help

Pic of box?

Sounds like the key/seatbelt/headlight reminder.

I agree on that. Probably the chime is disconnected, or PO hit it with a BFH.

See if the harness is disconnected under the drivers seat.

The little black box behind the glove box is the wiper control module.

Turn your key on and wiggle the blinker lever,if it starts clicking you have a broken wire inside the multi function switch(blinker switch).i bet one or more of your delay wiper settings dont work.

The box itself does go bad,rarely though.
