2014 Nissan Murano right front door does not lock or unlock.

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Murano. It sounds like you might have a faulty door lock actuator, which is common in vehicles after some wear and tear. This actuator controls the locking and unlocking mechanism electronically. If it's failing, the lock won't respond to the remote or door buttons. You may want to check with a trusted mechanic to confirm the actuator issue and get a quote for repair. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
