Power door lock still does not work after switch and actuator replaced
 

1993 s10 4 door blazer.

I'm trying to track down my last two problems. One can wait. So My power door lock does not work on the driver side. All the other doors including the passenger locks and unlocks with the switch. I replaced the switch on the driver side. Cleaned the contacts and replaced the power actuator. Still no go. I tried to volt it out but got nothing. Is there a relay for this? Also it does have remote keyless entry but I don't have the remote. Any help.
