Dancing mirrors!

[Dr Mike Oxgreen]

My door mirrors have stopped responding to the control buttons, and yesterday I noticed that every time I turn the ignition on, both mirrors do a little dance where they move in sequence to each of the four corners of their travel before moving back to a roughly central position. It's as if they're doing a calibration routine. After they've stopped moving, they still don't respond to the buttons.

I've never noticed this 'dance' before. Is it normal behaviour? Does it actually happen every time you turn the ignition on, and I've just never noticed it?!

Any ideas what might be wrong? I'm assuming it's not just a fuse, because clearly the motors are working.

its certainly not normal to dance around on mine, but no idea what would cause that

As yours is a '99 model my first suspicion would be the mirror control module that sits somewhere underneath the dash around the steering column. Given the symptoms on start-up and then the non-functioning I'd be checking there first.

This is a good shout, you can send your unit to TVR Heritage Parts for checking and repairing if necessary

Cool, thanks. It'll be going to Str8Six for its annual shortly so I'll mention it to them.

Are the door looms in good order?

I've no idea. But if you're suggesting that a short could be causing the motors to move, I think that's unlikely. The motors are moving together, in parallel, and in a definite clockwise square and then back to central.

I had a thought Doctor so I posted it.
Is the mirror control unit in the drivers door?
Off topic... Doctor, would you happen to own any videos taken from aircraft?
