Body - No Response From Power Mirror Adj. Switch
Power Mirrors Don't Work From the Adjustment SwitchIf the memory is corrupted in the power mirror control unit of a '05-06 RL, you can't move the mirrors with the adjustment switch, but the mirror down-pivot feature still works when you move the shift lever to and from R (as long as you've got the selector switch set to either L or R).
To fix this problem, you need to reset the power mirror control unit. To do that, just pull the No.7 (10A) fuse from the driver's under-dash fuse/relay box for 30 seconds and reinstall it. If you've still got this problem after resetting the control unit, press on with normal troubleshooting.
