I have a 2003 GMC Yukon, I installed an remote start alarm with the passlock bypass kit and the GMDL4 for the doorlocksabout a year ago, well everything was working fine until about 3 weeks ago when i arm my doorlocks dont lock or unlock, replaced the GMDL4 with a new one and still cant get the door locks to work. they do work when i press the door lock switch on the doors but not when arming. Please if anyone can help it would be greatly appreciated. Thanks

Have you Metered the wires for Voltage & Lock / Unlock Input??

If you know that the Unit has Power & Ground,.. Apply a MOMENTARY GROUND to the BLUE or GREEN wire to see if it Locks or Unlocks. If NOT then you either have a problem:

with the Unit

with the VIOLET wire

with Power & Ground

maybe programming ( which just turning on your key should do that )
