Never had a problem out of my door locks up until now. Now them working comes and goes. What is in the circuit? Anyone have the wiring? Is it a switch, relay and actuator? I get the feeling it may be the relay going bad. Where is it located?

 

probably loose ground or bad relay.im thinking a loose ground tho. look at your alarm and u will see the relay right next to it

 

Factory alarm? I don't even think I have one or an aftermarket. Where is it located?

 

The actuators can loose power, sometimes they are also greased. If that comes off, it can cause added friction. I would take off the door pannel and see whats causing it.
