I have a similar problem so I'm hoping you can help!
My drivers mirror no longer moves in the vertical plane (it use to with some help) but is fine in the horizontal plane. My passenger side is the same, whether moving it using the controls or selecting reverse (which would normally tilt the NS mirror down).
Sounds like I have a motor out on each side. Do I have to buy mirrors from a 250 to salvage the motors?Or can I buy from an IS200/ 300 for example? I'm really hoping the motors are the same part
