The time and alarm control module is behind the center of the dash below
the radio. If you have cruise control, it'll also be below the cruise
control module.
You won't be able to troubleshoot the ETACM without checking all the
pertinent inputs and seeing if you receive the appropriate output. The
ETACM controls several functions, so I don't know how to specifically
advise you. If you let me know what your symptoms are, I may be able to
offer additional assistance.
