I recently bought a 99 accord 2dr, the only thing wrong with it is the door locks, you can lock/unlock them manually with key or pushing them down, but with the button or key fob nothing happens, except a click, and the security system don't arm unless i use the key. if its an actuator, can i buy them together or are the door specific?

 

My diagram could be wrong, but have you checked the no. 12 fuse in the passenger side fuse box yet? Also, is this an EX or LX trim level?

 

Yes, check the No. 12 (20A) fuse in the passenger side fuse box.

The actuators are door specific. However, before replacing them, I would:

• check the fuse
• test the actuator motors by applying direct power and ground to them
• test the driver's door multiplex control unit.
