I have the Comfort Seat option in my 4.6is. I have noticed before when in reverse the passenger mirror should dip, but it dips then comes back up, dips again and so on and so on until you take it out of reverse when it will return to normal position.
I have today also found the drivers seat back will not recline forward on the electric switch, it will however recline back. Heres the weird part - If I press a memory button it reclines forward ok, so I know theres no problem with the seat motor.
Is this likely to be one dodgey wire to the recline seat switch? Only started today
Any ideas why the mirror does that? Been like it since i got the car.
