A few weeks ago, our rear wiper stopped working correctly. If you turn it on, it does nothing, but if you put the car in reverse, it runs. That was an inconvenience, but we dealt with it. Yesterday our key fob stopped locking the car. Then today, the interior lock buttons don't work properly. Each time you press the button, you can hear it trying to click, but no movement, if you press the button about 20 times, it will finally unlock or lock. We're thinking these two things have to be related, but not sure. We've disconnected the battery and reconnected to see if that helped and it did nothing. Does anyone have any ideas? Is this something we can fix, or something we need to take in to be repaired?
