Door lock actuator problem
I have a 2002 Grand Caravan with power sliding doors. 2-3 years back, the drivers side power door lock quit working. It would twitch, and ocassionally work. I removed the actuator and it seems that the actuator motor will not operate the mechanism far enough for it to complete a lock/unlock cycle. I decided to just live with it. Recently I came across an actuator from a salvage yard. I installed it, but it does the exact same thing - it won't fully complete a cycle. So now I'm wondering if this is a coincidence that two actuators (albeit neither one is new) act the same way, or is there possibly a different issue, such as maybe the HAL9000 computer (joking) not supplying enough voltage, or not providing voltage long enough... I tried cleaning the contacts inside the actuator, everything looks normal enough (considering I don't have a new one to compare it with). Any thoughts or fixes? Others having the same issue? Thanks.
