How to Troubleshoot Toyota 4Runner Mirrors
The Toyota 4Runner is one of the most popular Japanese SUVs in the market today since it was launched back in 1984. Driving this huge vehicle is easy, but you need to make sure that all parts are working perfectly and that includes your mirrors. Old mirrors that are adjusted manually are easy to troubleshoot, but newer models are now equipped with electric mirrors and they come with their own set of problems. Troubleshooting Toyota 4Runner mirrors is pretty easy, so just go through our short guide and find out how.
You can easily adjust both side mirrors from the driver's side thanks to a couple of switches on the armrest. But once they develop problems, then you might have to adjust both mirrors manually until you get them fixed. Other features like automatic heating and dimming mirrors can be narrowed down to electric problems as well. If none of the switches for your mirrors are working, then the first thing that you should check would be the fuse box. A blown out fuse is quite easy to replace, so go through your manual and find the one for your side mirrors. If your mirrors still aren't working, then you might have a loose connection and would need to open the housing itself.
Your vehicle's mirrors simply won't work if they've got a bad connection. Check your mirror's wiring for voltage using a multimeter or a test light to rule out any other problems. If there is no voltage coming from your wires, then you probably have a loose wire somewhere and would simply need to patch it up. If there's voltage coming through your wires, then your mirror housing might be broken and you'll have to replace it instead. Your vehicle's manual would have a diagram for identifying your mirror's wiring so you could perform this test correctly.
Unfortunately, most mirror assemblies are sealed units and cannot be repaired. You can ask a mechanic to make a thorough check of your mirror assembly before you consider getting a replacement. Installing replacement Toyota 4Runner mirrors is pretty easy and you could do it at home on your own.
