Diagnosing Faulty Rear Blinds

[chrisc201]

Hi folks,

Recently bought a D3 A8 that has electric blinds on the back doors but both are entirely unresponsive... Read that pulling and holding the window switch for the door also activates them and again unresponsive so not sure if this implies a motor issue rather than switch?

Any advice on how to diagnose would be appreciated, clearly not a must have item but working my way through a few issues and would like to get everything working.

Cheers,
Chris

Hi Chris,

There are two ways of operating the side blinds - the roof console above the rear seats and the window switches.

If neither are working, it's unlikely to be the switch (especially if the window switches still work to operate the windows).

Do you have access to a scan tool to scan for errors?

[chrisc201]

Yes tried both and no response at all from either.

Psyche from this forum has kindly offered to run a scan (other issue) so maybe that will shed some light, assuming checking voltage at the motor when activating the switch to check for increase would help diagnose...

Cheers,
Chris

How are they fused?

[chrisc201]

Hmm....good question..... Does seem like the circuit isn't completing due to the complete lack of any noise....

Any one know if there is a fuse specific to them?

For clarity the rear electric blind and rear electric windows all work fine....

Cheers,
Chris

Check the manual, I don't have a D3 any more but you will find a fuse diagram/table and that would be my first point of call
