So about a year ago the left rear door lock actuator quit working. not a biggy, just annoying having to manually lock/unlock the door. But this morning I noticed that I didn't get the "click" sound I normally hear when I unlock the doors. Looks like there is power going to the actuators but they are weak or didn't work at all. (as in all the doors now) I have not dug any farther into the issue as of this first post. Any ideas, suggestions?
