Warning Signs the Mirror Memory Control Module is Failing
- Your side mirrors don't move when you press the memory buttons.
- The mirrors move erratically or to the wrong position.
- One or both mirrors don't adjust at all.
- The memory function doesn't save your mirror settings.
- The mirror adjustment switch works intermittently.
How to Test if This Part is the Problem
It can be tricky to know if the mirror memory control module is the problem. Here's how to narrow it down:
- Check the fuses: Look in your car's fuse box for the fuse related to the mirrors. A blown fuse is a common cause of mirror problems. Replace it and see if the mirrors work.
- Test the mirror adjustment switch: Make sure the switch itself is working. If the switch doesn't work, the module won't get the signal to move the mirrors.
- Inspect the wiring: Check the wires going to the mirrors and the module for any damage, like cuts or loose connections.
- Swap with a known good module (if possible): If you have access to a working module from a similar vehicle, try swapping it in to see if that fixes the problem. This is the most reliable test.
- Consult a mechanic: A mechanic can use diagnostic tools to test the module and other components in the mirror system.
Common Failure Causes for This Part
- Water damage: Water can get into the module and corrode the internal components.
- Electrical surges: Power surges can damage the module's circuits.
- Vibration: Over time, vibrations from driving can loosen connections inside the module.
- Age: Like any electronic component, the module can simply wear out over time.
