Symptoms
- Mirror doesn't move in any direction from the switch
- Mirror moves in some directions but not others
- Grinding or clicking sound when trying to adjust
- Auto-fold feature doesn't work but manual adjustment does
Likely causes
- CommonBlown mirror control fuseA shared fuse can disable both mirrors' power adjustment.
- CommonWorn internal mirror motorThe small motors inside the mirror housing wear out over years of use.
- PossibleFaulty mirror control switchThe switch used to select and move the mirrors can fail internally.
- PossibleDamaged wiring in the door (often near the hinge)Wires flexing every time the door opens can eventually crack.
What to do
- Test both mirrors from the control switch to see if the issue is one mirror or both.
- Check the fuse box for a blown mirror control fuse and replace with the correct amperage.
- Listen for a grinding or clicking sound when adjusting, which suggests a motor or gear issue inside the mirror.
- Try selecting the other mirror on the switch (usually L/R selector) to rule out a switch fault.
- Check if auto-fold or heated mirror functions work while manual adjustment doesn't, which helps narrow the fault.
- Open and close the door slowly while testing the mirror to check for wiring flex issues.
- Avoid forcing a stuck mirror by hand, which can damage the internal motor further.
- Have a shop replace the mirror motor assembly or trace wiring if basic checks don't resolve it.
