i believe you can retrieve diagnostic trouble codes from the atc in a similar manner to the wj climate control, though i'm not sure on the exact procedure. and am not sure where to look for it for you.
a quick google search hasn't turned up anything for the 97/98 model, but did turn up a refernce for the early models. i'm positive the climate control changed by 1998 though.
