Driver's side door not locking
 

Fellas...need your help. The driver's side door does not lock when I use the remote. All other doors, gas flap and trunk lock, but the driver's door remains unlocked. It can be locked manually when I get in the passenger side and subsequently unlocked when I use the remote or door handle. I have keyless go if that helps.

Any help or knowlegable guesses would be appreciated.

Thanks.

Power lock actuator power, or the actuator itself.

Thanks vettdvr. What is an easy way to tell which one of the two it is?

BTW, I had my first experience in a 08 Z51 the other day at Bob Bondurant School of High Performance Driving. I was able to autocross and run the car on their closed circuit track. I have a new found respect for Corvettes now!
