Key Fob Remote Door Lock Fuse Question

[Burlroad]

A few weeks ago I noticed my remote key fob stopped locking my front entrance door on our 2003 Lexa. It still seems to be locking and unlocking the bay doors as I hear the actuators working.

By chance is there a fuse that sits somewhere between the front door actuator and the 12 volt power supply? I see nothing in the manuals indicating as such.

I assume the actuator may have given up to ghost in the front door but appreciate feedback from any of you that have been down this road.

Thanks

Update.... I have validated that the actuators is the front door are working when I give them 12V. As it turn out, some of the bay doors are locking and unlocking with the key fob, but others aren't. (Including the front entrance door lock)
The only thing I could see in the manual is the fuse for the alarm control box which is associated with the cargo bay lights. However that fuse is fine. I'm at a loss.... everything worked several weeks back with the key fob but now the front door as well as some of the bay doors aren't responding to the key fob lock and unlock buttons.

Thoughts?
Thanks, David

Sometimes the TriMark board will go bad on you. Also check the door itself. I had comparable problems. Looked at the wire harness running into the door (right below the hinges) and saw that some of the wire assembly had stripped away. Took it to Premiere in Junction City. They confirmed the stripping of the wire harness at the door hinge had caused some of the intermittent problems between the FOB, front door. Then the motherboard went bad. lol.

Had the same problem, bad wire in the harness at the door jam. The wires eventually break from being bent back and forth opening the door.

I wonder if thats my problem. Mine used to "chirp" the alarm and flash the lights. Now just the lights flash. I need to see if the alarm even works too, I haven't set it off lately!
