Door Mirror Control issues

[blaze_away]

I am having trouble with the door mirrors.

98 Chimaera with the aluminium control panel in the door.

The problem is that when I switch on the ignition the mirrors are silent, as normal. If I click on Left or Right selector button that mirrors motor then starts whirring away.

The left/right/up/down buttons have some effect but it seems the mirror goes to a down/left limit and stays there.

It continues to make the whirring noise whilst I operate the left/right/up/down buttons until I stop it by switching off the ignition.

I have stripped the switch down and cleaned every thing so its not a stuck switch, (still has the problem with just the bare switch circuit board connected).

Is it a 'known problem' ?

What should I be doing now to fix it ?

The insulation on the wires tends to break over the years. Especially where they pass through from door to car. Mine can move randomly with the ignition too.

OK that's good to know thanks, will go and attempt to get the harness out of there and see what its like.

I think those also have a mirror control ECU.
TVR Parts offer a repair service so they may be able to advise if there are any common failure modes.

Blimey, wasn't expecting that, and yep looks like they have them.

wires that went trough door area all look ok no amount of waggling changed anything.

Good. That’s one thing ruled out. Just got to get around to fixing mine!
