Took the mirror out, the wires seem ok and connected ?
I've got the same problem. Started this morning :/
I read through a few other posts on the site - looks like it's either a dodgy connection to the motor/heater, the mirror glass, or the actuator/motor (which is also the heater apparently).
Did the glass come out easily? I was going to try tonight - other posts just say tilt it to one side and pull gently...is that right?
If it's the glass, then that's only £30 from Honda and sounds like a 5 minute fix. If it's the motor that's £65 and not a 5 minute fix
Have you got anywhere with yours since you last posted??
