I would also chase the alarm problem you’re having as Lochinvar has suggested.
I may also consider plugging in an obd2 scanner to see if any codes are showing up ...
A clicking from the dash area could be a relay going bonkers. I’m not sure of the layout of the Gen1, but the Gen2 PCM plus a handful of relays are behind the glovebox which can sound like the passenger side dashboard is clicking. Is your clicking originating from a fuse box area Or an area where a relay is located?
