Recently my power locks have quit working in my 1996 K1500 Z71. I thought it was the fob at first but I realized it wasn't when I heard the locks still trying to engage but failing, like the power wasn't getting there. I took the actuator out, is there any way I can check to see if it's the actuators acting up before shelling out 90 bucks to replace the two of them or is there anything else I can do? Any help is appreciated.
