So I finally have some free time to fix all the small issues with my Crossfire. For the past year my car will unlock automatically when I get out of my car and manually when I push the button, but when I try to lock the doors nothing happens.

Also, may or not be related. But my horn doesn't work as well. When I press the horn I can hear a click near the RCM, but I haven't traced the wiring yet.

Fuses are already checked and are all solid.

Any advice would be appreciated.
