What makes you think the door actuators are fine ? The lock is not fully cycling, which would make me think the actuators could be
giving you a problem.
The clicking noise could be a few things, but let me ask:
. When you hear the noise, is it seem like it is from the oval area where the AutoLamp sensor is at ? ( Seem to recall right at the moment, that is where the lock relay block is at ..could be mistaken ? )
. Is the clicking noise at all times you try to use the Power Door Locks, or just some times ?
. Does it click when using both the switch on both doors AND when using the RKE ?
. Does it click on both the first and second button pulse of the RKE ?
I don't know what the dealer is thinking with the RAP, that is a solid state device, should not be clicking, unless it is clicking without you doing anything.
The RAP sends a ground signal to the driver's door unlock relay, and then second pluse would activate the unlock all relay.
If you pull up on the oval on the dash where the little grille for the AutoLamp sensor it at, you should see a relay block with 3 relays in it.
. Put your finger on the plastic relay housing ( no you won't get shocked ) 1 at a time, and see which one is clicking when you try to unlock the doors ( or lock ) and start there. You should fell the mechanical action causing the clicking by doing this.
Don't have access to my EVTM until I get back into the H.O. later tonight, but this is what my feeble mind is digging up in the back, behind the Life cycle covered in clothes, and under 2 dust bunnies
