Question: Rear Door lock

I need to see why rear door locks are not moving smoothly and now the left rear does not lock at all, even with the button down. Cannot figure out how interior panel comes off. I know it has clips and I have pride them up around edge, but cannot locate any bolts or screws holding it in place.

There are screws somewhere. You might check youtube to see if someone posted a video on how to remove the panels. I'd need to see the vehicle to tell you.

I went to the Local Pep Boys and ask a service Rep. We went out to the car and he showed me where they were. I went back home and removed it. The Lock Mechanism had popped out of its hole in the door frame somehow. I got it back in and it is locking again. But neither rear door will lock with the power button, have to lock old fashion way.

If both doors won't power unlock/lock, you probably have an electrical wiring issue between the switch and the doors.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
