if you find someone with a scanner this system stores trouble codes and gives you the chance to actuate the doors with the scan tool

could be the mode door actuator bad or the control head to many things to just pick one

well if you can get it scaned and it is an actuator that is fairly easy job to do the control head is to except it may need programming after replaceing it
