This video shows you how to diagnose electric door latches! Modern cars with power door release and actuation rely on electrical activation with buttons and switches! Unfortunately, like other electrical components, they have several avenues of failure: wiring, fuses, shorts, and even communication with other systems. Watch this video to see how to diagnose these problems, and why our rear door wouldn't open. The answer may surprise you!
