I believe that a malfunctioning relay would be the problem, because its on its way out, and you need to giva that one a try. If not, then one of the wires that controls the switches or in between is exposed and is reacting in the aforementioned way (Not that im 100% sure, but im just using common sense)

I'll see what I can do for diagnostics from my FSM...

(Morty...remind me to make you do this tonight.)

Although my car is light years behind the times, I had a somewhat similar problem. I do not have any remote lock feature just the electric door locks. About two years ago I locked the doors and after I closed the door the locks would unlock automatically. It turned out to be a stuck contact behind the drivers side door lock faceplate. Ya neva' know?!

I checked fuses and relays this weekend. Found nothing wrong there. I've done some searching around here about the BCM and RFA. Sounds like there may be some sort of check that can be run on the BCM? I'm still not exactly sure where the BCM and RFA are at...under the dash on pass. side?

I blame Morty...

Should be laid up on the couch tonight with a bum knee... if you don't see anything by 7pm EST pm me..

Washers:
Connect a test light between terminals A and B of the washer pump connector (harness side).
Activate the washer switch while observing the test light.
Is the test light on?
Pretty much saying it'* the switch if you don't have power.

Go to Step 3
Go to Step 5

3
Turn the ignition switch to the OFF position.
Disconnect the MALL module connector C1.
Use a Digital Multimeter (DMM) set to the ohms scale in order to measure CKT 294 (TAN) resistance from connector C1 terminal A to ground.
Is the resistance within the specified range?
0-5 ohms
Go to Step 4
Go to Step 10

4
Repair CKT 294 (TAN). Refer to Wiring Repairs in Wiring Systems.

Is the resistance within the specified range?
0-5 ohms
