Rear door handle doesn’t work

ANSWER : Hi there. Sure would appear a lot is going on electrically all at once. This could be, a problem in the PDC (power distribution center). The PDC is typically located under the hood and contains numerous fuses and relays. I don’t believe any one fuse will resolve all of the electrical issues. There is a possibility, it is not a power supply issue. It may be, the result of a poor electrical ground common to the inoperative components. Proper circuit testing should be performed. This would confirm the cause of multiple electrical failures. I recommend having your vehicle’s electrical problems be diagnosed and repaired by a certified technician, such as one from YourMechanic.

ANSWER : While it appears that your Fusion enjoys your company a bit too much, rest assured, you are not alone. Many Fusion (and related Milan and Zephyr) owners have reported similar concerns when attempting to open the doors using the interior handles. Unfortunately, the push to make cars lighter, as well as reduce production costs, has driven manufacturers to make as many components out of plastic or composite materials as possible. The interior door handle is yet another casualty of the “war on weight”. As time progresses and the handle is used repeatedly, the plastic fatigues and eventually cracks.

Unfortunately, when the handle completely breaks, the lock feature for that door is typically inhibited. If there is a silver lining to be found, it may be the fact that handle replacement rectifies both issues the vast majority of the time. My recommendation is to have a technician replace the broken handle, and re-inspect the power lock system for proper function once completed. This service typically takes less than an hour. You can contact YourMechanic for estimate.

ANSWER : I would recommend against doing this. Most vehicle door handles are not compatable from front to back. If you have a junk yard near your location, you can usually get parts such as door handles very inexpensively. I would recommend doing this over swapping the rear door handle to a front door handle. Unfortunately, there are many vehicles with this exact same problem of being made with door handles that were not meant to last.

ANSWER : The window motors are a common failure. Sometimes the cable in the regulator can come off track and wrap around the gear on the motor and do some damage. As far as the door lock you may have an actuator failing. Many of the door locks on VWs and Audis were air powered, but your concerns sounds like it’s electrical. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look and your electrical concerns and offer a more personal diagnosis.

ANSWER : Hi there. These door issues are common on this vehicle. Most of the time the main issue is the master door lock switch on the driver door. It sounds like you already replaced that. As for the sliding door problem, most of the time, this is a failure within the door module or it can be a connection issue.

I typically take the door apart and check the connections on the module and inside of the door just to make sure that there is nothing apparent in there. If the connections and the wiring are fine, then I use a scan tool to check the module to see what the inputs and outputs are doing. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your door problem and recommend a repair.

ANSWER : Hi There,
This is usually a problem with the power window motor, the regulator or the fuse. The power window motor is what actually operates the window up and down when you push the switch. The regulator is what actually moves the windows up and down which is powered by an electric the motor when you use the switch inside the vehicle. The fuse is designed to protect the entire electric power window system in the event of a short or some other electrical failure. In the event that the fuse blows, this will cut the power to the electric power window motor, rendering it inoperable. I would suggest having a professional from YourMechanic come to your location to diagnose and inspect your power window system to determine what may be causing not to work properly.

ANSWER : Hi there. Unfortunately, without knowing specifically what you may have removed or worked on, it’s hard to give you an idea as to what the problem might be. It could be an electrical relay problem, exposed electrical wire or a mechanical issue with the door lock itself. In order to help out, we’d need to complete a car door will not open inspection at your location.

ANSWER : Hi there. In general, wiring harnesses are sold by the manufacturer as a whole harness; not individual wires. It is much easier, cost-efficient and safer to replace the entire harness if it’s determined that it is faulty and the source of your alarm / door issue. It would be best to have one of our mobile mechanics come to your location and complete an electrical problems inspection though, as it’s possible that this issue is related to an error code trapped in the ECU. If this is the case, simply clearing the code will resolve the problem. If the issue is determined to be the wiring harness or an exposed wire, they can recommend and most likely complete the repairs as well.
