You could try cranking it a couple times then taking a plug out and seeing if there is fresh gas on it. Sometimes you can here it come on when you are turning the ignition right before you start. It is a humming winding kind of a sound. I dont know if one can hear it on a Caravan though. Hope this helps.
If the interior lights come on and go of and chimes sound off f on a 1997 Dodge Caravan there could be a loose connection somewhere. This is a common condition with the Dodge Caravan series.
Special Edition = upgraded sound system, suspension, et. al. Depending upon the year the SE stands for standard edition example 2002 dodge grand caravan SE is the lowest version of the car.

There are two "i" in the word "winding". The first is long. The second is short.
I had the same thing on my 2002 caravan sport and I changed the caliper, rotor, and pads and no more clicking.
