Where is the RAP Module?

Module —Remote Anti-Theft Personality (RAP)
Removal
CAUTION: Electronic modules are sensitive to electrical charges. If exposed to these charges, damage may result.
Disconnect the battery ground cable.
Remove the LH front door scuff plate.
Remove the LH cowl side trim panel .
NOTE: If C256 is disconnected first, an inadvertent IGNTAM alarm event (AL_EVT) will be stored and the alarm will sound. The alarm must be disarmed by the remote unlock button or a key in the door lock cylinder to UNLOCK. To avoid this condition, disconnect (1) C257 before (2) C256 and reconnect (2) C256 before (1) C257.
Disconnect the two remote anti-theft personality (RAP) module electrical connectors.
Disconnect C257.
Disconnect C256.
Remove the RAP module nuts and the RAP module.

RAP Module
Mr. Torkum: Many thanks. Directions could not get any better than that. JLM

When you say clicking under the dash, could it be under the oval ( something is telling me that is where the relays are for the RKE ).
With the Remote Keyless Entry ( RKE ) there are relays added to the PDL.
The CSM ( central Security Module or what used to be the RAP module / Remote Antitheft personality ) is not inline with the PDL, but actually triggers the ground on the Driver's unlock relay.
The switches in the door are connected to the coil ( supply ground ) for the all lock & all unlock relay ( depending on which way the switch is pressed ).
The problem could be either bad relays, or switches that are not correctly supplying ground to the all lock or unlock relays.
Here is the diagram from the 2000 EVTM ( when the RAP was in, CSM is the same circuit ).

If you pull the all lock or all unlock relay, and jumper the relay socket across pins #3 & #5, the door locks should cycle.
If they don't, it could be a lock actuator that is giving you problems.
The clicking of the all lock or all unlock is similar to the symptoms that one might see from the Power Window motor failing ( saw this on my Dad's 2001 ).
This diagram will show which pins in the relay socket to jumper across for testing :

Might be a good place to start with testing the lock actuators by bypassing the switches.
