You have a bit of a problem but there is a solution.
The odds are not only do you not have the clicker, you do not have any warning bells, buzzes, headlights on noises either.
This is because all these noises come from a speaker that is mounted on the printed circuit board of your instrument cluster.
The solution is to remove the instrument cluster, tap into the speaker wiring and mount an speaker external to the PCB. Some guys have mounted a new similar speaker but it is hard to find one that fits plus if you just extend the two conductors out of the cluster, then next when the speaker goes, you just replace the speaker.
Also since finding a suitable speaker is a bit of luck, if you choose one and do not like it, then you just find another and tap into the wires already in place.
This is how to remove the instrument cluster.

How to tear apart the instrument cluster. Note do not pull off any of the needles - it is not needed to get at the speaker and most people cannot get the needles back on correctly.
