Troubleshooting Your Toyota Pickup Mirror
With the Toyota pickup mirror, you can easily see your rear surroundings without having to turn your head towards the back. Because it is a safety component, you cannot drive without it installed. However, the rear- and side-view mirrors are also capable of failing, especially if they are electrically powered. If your pickup truck has mirrors like these, then you have to know what to do if they get faulty.
When one power side mirror does not work
One of the problems you may encounter with your vehicle is when one of the power side mirrors does not work. First, check the switch that controls the component's movement. Then, access the faulty mirror's wiring and, using a multimeter, check for power while you are moving the switch. You may also want to try pulling off the door panel and inspecting the wiring inside. Use the multimeter as well to check if one of the connections is not getting any power.
When both power side mirrors do not work
If not one but both of your power side mirrors fail, the first thing you should check would be the instrument panel fuse and see if it has blown. If it has not, look for the fuse underneath the control panel, which is usually where the fuse for the mirrors is found, and see if it is blown. Replace any blown fuses you see just to make sure. If both mirrors are still not working, then there might also be a problem with the switch. Test the wiring for power, and if it registers enough volts, then the switch needs to be replaced.
When the electric rear-view mirror is your problem
If you are experiencing problems with your rear-view mirror, you can do the following diagnosis. Note that you do not have to start the engine in order to operate your rear view mirror. Just turn the ignition switch and the component will receive power from the battery.
While operating the mirror's control switch, listen for the motors running. If you can hear them, then it is likely that the mechanism inside the component's housing has a problem. To get rid of this issue, you will have to replace the motor or the entire mirror assembly.
If the electric rear view mirror is not working, immediately check the main fuse for the component's circuit.
