power door locks won't work
 

Hi, I have a 2000 Dodge Intrepid and none of the power door locks will work. When I press the switch from both the driver and passenger side doors, I can hear the relays clicking but nothing happens. Has anyone else experienced this type of problem? I've tried swapping the relays and changing the 20A power door lock circuit breaker, but nothing has fixed the problem. I don't have much experience with power lock systems so any information would be greatly appreciated.
