My window on my passenger side won’t roll down and the lock button doesn’t lock the doors.
I have a 1997 Mitsubishi Eclipse 2.0L DOHC (420a engine) and my problem is driving me nuts.
The driver's side will lock BOTH doors and roll down the driver's side window. The driver's side switch will not roll down the passenger window. The passenger switches don't work at all, meaning they won't roll down the passenger window or even lock the doors. I disassembled the passenger door and completely removed the switch, but the window still will not roll down from the driver's side door. I'm stuck between wiring, switch, and/or possibly the window motor itself too. I

Experienced mechanics share their insights in answering this question :
Hello, thank you for writing in. Your issue is most likely a switch. The window motor would not effect the door lock functions. The only true way to know is to test the power available to the switch and see if it is passing through, or making it to the motor. Where the power stops and is not utilized, is the component that has failed. If the power supply is not making it to the switch, then you have another wiring or fuse issue. Without doing some electrical testing, you may want to start with replacing the switch.

If only one door isn`t working, there`s likely a problem with a door switch or sensor. If this is the case, you`ll need to have a mechanic take a look at your car. If all of your doors don`t open, you could have a blown fuse.
A problem with one lock is probably due to the lock actuator or another malfunction inside the mechanism of the door itself. But if none of the power locks work, check the fuse box in your vehicle. A blown fuse can cause the power locks to stop working.
A blown fuse is the common hurdle in locking doors properly. Car doors rely on this fuse`s command to lock or unlock. The fuse is usually located under the glove box (passenger`s side) and can get blown due to high voltage. The fuse is cheaper and can be easily replaced at home.
Door lock problems are often caused by a malfunctioning lock mechanism or latch assembly, but there are several common reasons why locks stop working: The lock is dry or dirty. It doesn`t fit in the door properly. The latch and strike plate don`t align.
One common reason the car door lock is stuck in the locked position is due to broken connections within the door panel or lock assembly. These include a broken link from either the handle, lock cylinder, or interior locking post/switch to the car door latch.
A door locking motor is fitted to each door and connected to a control box located under the fascia in front of the steering wheel. A 20 amp fuse is incorporated to protect the System, see figure 1.
How Do I Know That My Door Lock Relay Is Malfunctioning? If the doors refuse to lock when you press the lock button but unlocks when you press unlock button.
On many modern vehicles, the lock actuators are monitored by electronic controls (such as the body control module) that have to receive the correct antitheft code from a key fob transmitter before they`ll send electrical current to unlock the doors.
The majority of cars now have remote central locking, however, with a flat or dead battery this won`t work and you will be forced to use the key to open the car doors.
If your ECU controls the anti-theft system, disconnecting the battery may lock you out of your car. Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.
An electric window circuit
The switch is wired to the battery via a relay and a fuse or a circuit breaker. Although they can be a real convenience (no more leaning over the passenger seat to open or close the window) they can also be a considerable annoyance when they stop working.
Fuse lockouts and blockouts are highly visible devices that feature a unique locking mechanism that prevents the device from being accidentally removed from a fuse block. They will help you comply with OSHA`s lockout tagout standard.
Which two keys cant open any door: The answer to this question is Don”key” and Mon”key”. EXPLANATION: The definition of a key is that it`s a small piece of shaped metal with incisions cut to fit the wards of a particular lock, which is inserted into a lock and turned to open or close it.
Yes, a locksmith can help with a key left in the door, this is a simple job where any good locksmith should get you in with absolutely NO damage to your lock; there should be absolutely no need to drill the lock.
Disconnect the lock rods and cables
Some actuators come with new cables attached to them; others are bare. It may be necessary to disconnect lock rods and transfer them to the new actuator or latch. There might be door lock cables attached that need to be replaced as well, plus an electrical harness.
As the battery wears out however, the range and signal strength of the fob transmitter will be reduced. If you notice that your key remote does not unlock your car, lock your car, or start the engine for those with the automatic start button as early as it should, it`s probably time to replace the battery.
A diagram of the fuse panel where the fuse is located will be found in your owner`s manual; the fuse you are looking for should be labeled “steering lock.” If you would like help, a technician from YourMechanic can come to your home or office to inspect your steering lock issue and make the necessary repairs.
A blown fuse prevents power transfer to the actuator, thus disabling the lock system.
If the switch fails completely, it will not be able to conduct power to the door lock actuators, and as a result, the door locks will not function. While most power door lock switches are built to withstand extended use, they are still susceptible to failure, and can be an inconvenience for the driver when they do.
The only tool required to check a relay is a multimeter. With the relay removed from the fuse box, the multimeter set to measure DC voltage and the switch in the cab activated, first check to see if there are 12 volts at the 85 position in the fuse box where the relay plugs in (or wherever the relay is located).
The door control module (DCM), also called a door control unit (DCU), is a type of automotive electronic that provides intelligent control for vehicle doors, and their peripheral electric parts and components, that enable features such as power windows, anti-pinch technology, central door locking, rearview mirror …
Door lock actuators are an electronic component found on vehicles equipped with power door locks. They are the electronically controlled actuators in every single door that are responsible for locking and unlocking the power door locks when the switches are pressed.
When the alternator fails, other systems that are connected to it may also start to malfunction. These include things like power windows, locks, lights, air conditioning, and even your radio. Other factors might be at play, but it`s worth getting your alternator checked by a reliable auto mechanic.
The latching mechanism in a vehicle is installed directly in its doors. It contains both a latch and an electric motor (actuator) which controls the central locking. The latch opens or closes the doors, whereas the door lock locks or unlocks the vehicle. Today, all door latches are powered by electric drives.

Driver side door lock button not working, and passenger side sliding door makes a buzzing noise
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.
all doors lock only by inserting key in passenger side door and locking
ANSWER : Your central locking system may have been designed with a control module in the circuit. This is a small computer that is responsible for controlling the different functions of a particular system. It is possible that the module for your central locking system may have shorted out internally preventing particular functions from working properly. I would recommend having a certified technician test your central locking module to determine if all of its functions are working properly.
Driver and Passenger doors won’t lock, but I hear them click and see the locks twitch.
ANSWER : If the same problem is happening even when you use the inside door lock switch then the most likely cause of the locks not moving is going to be weak actuators. You should replace the drivers lock actuator first since it is used the most and you will see it fixes the problem. Then you can replace the other doors as needed.
Front Passenger Lock sometimes does not lock with a remote control or by locking button located on either doors.
ANSWER : The solenoid is on the door latch and is most likely the cause of the problem for your 2005 Toyota Tacoma. If you want to have this inspected and repaired, a certified technician from YourMechanic can come to your home or office to diagnose your door lock and perform the correct replacement.
Having a problem with the passenger side window switch; the window will go down but not back up
ANSWER : Hi there, this issue generally comes up often when we see a power window that does not work on the passenger switch, but still works with the driver’s master switch. It means that the passenger side window switch has failed. The fact that the drivers switch operates the window properly lets you know that the window components all function properly as that the problem is probably electrical.
A technician that is diagnosing this would use the wiring diagram to find the proper wires to test and check for power when the window is rolled up to see if there is power present when the window is commanded to roll down with the switch. Given that you are still under warranty, this scenario should be something the dealership would resolve free of charge as part of the warranty. If the vehicle is only under powertrain warranty and not the full warranty, the technicians at YourMechanic are able to provide diagnosis for your window and can perform a power window switch replacement for you if necessary.
Having problems with door locks on 08 Cadillac CTS. Driver side door especially and will not lock or unlock with key. Others loc
ANSWER : This is often related to a malfunctioning door lock actuator, a blown fuse or a faulty power door lock switch. When you use the door lock switch in the car it sends a signal to a relay which then activates an actuator inside the door. The actuator is the final step in the process in that it is a small motor with a set of gears that actually locks and unlocks the latch mechanism inside the door allowing the door to open. When this motor is bad, the latch mechanism will fail to operate and cause the door not to unlock as it is designed to. In the case of a bad door lock relay, the power, normally needed to send the signal from the switch when you activate it to the actuator motor is not there. This means the relay is not allowing the circuit to be completed and the actuator motor is not activated. Any of the above may cause your power door lock switches not to work properly and should be diagnosed by a qualified mechanic. I would suggest having a professional from YourMechanic come to your location to take a look at the door locks in your vehicle.
Inside driver side and passenger side door locks do not work and that is the only way that I can lock my car.
ANSWER : You may have two bad latch door lock actuators. The only way to tell is to take the door panel off and test the actuator to see if they are getting power and move freely. This is a very common problem and a mechanic can remove the door panels and test the locks out for you.
