1993 Ford Ranger Door Locks

I have a 1993 Ford Ranger that was previously wired with a black widow alarm and aftermarket actuater door locks.  I have removed the old alarm and installed an audiovox ax500 alarm with keyless entry.  The only problem I am having with the alarm is that the door locks don't do anything.  The locks are wired in the Actuators/Reverse Polarity Style (see diagram).  I have double and triple checked the wiring, but nothing seems to happen when I arm or disarm the alarm.  I do feel a slight click in one relay when I arm and another relay when I disarm, but the actuators do not respond at all.  Could this be bad relays, bad actuators, or something else?-Kenneth Merenda

OK, I have made some progress on my own.  I have replaced the two relays and have checked the lines going to the actuators for electricity, and the wires and relays are working perfectly, just no movement or sound or anything from the actuators.  Is there anything else I should check before I replace the actuators?-Kenneth Merenda
