    My drivers mirror isn't clearing in the mornings for some reason. I've tried swapping the connectors but its made no difference.

    Is there a way you can force it to warm the glass so I can check if there is a current getting to it?

    Maybe the heating element is broke, it's pretty common. I think if you have the mirror adjuster set in the middle and hit the rear demister button, they come on manually.

    i have had this discussion with an Audi tech....he was saying the middle position turns off the heaters (as i had a couple elements break), although both this car and my T plate A3 had the heaters on all the time regardless of switch position

    Believe the mirror heaters do stay on all the time, eventually causing them to burn out, i think the only option is to get a new mirror glass, to remove the original can be an arse sometimes, as they can shatter, sending broken glass down the side of your car!!!

    I have the same problem on mine, just use my hand to wipe it now..lol

    hmmm im quite confused about when they operate...

    Last night the mirrors came on initially when i started the car but when i checked them again (after 40mins of driving) they were off...

    Do they only come on for the first few minutes of driving ?

    They only come on when the temps outside are 5DeegreeC or below, and switch off when warmed up. They have a built in stat.

    Pre facelift cars they come on all the time, and facelift cars have a small bi metal temp switch on the back of the glass that activates at around 5 degress or less, but obviously will switch off when it gets warm.

    Its all controlled at the glass so if you really want to you can switch on the ignition and check for voltage with a DVM or a bulb at the two wires in the mirror housing

    facelift cars have them come on at 5C or colder (when the snowflake symbol is shown next to outside temperature on the dash) and with the rear de-mister
