Driver's side heated mirror not working

Hmm, got in the car this morning, lots of condensation/frost on the car from the night sky - after a few mins driving the passenger door mirror had cleared fully, but my driver's side one had not cleared at all. Wiring, or element, or fuse, or something else? Any BTDTs on this one?
 
Forgot to add, the rear screen demister works fine, and I was getting heat from the ventilation system after a few mins so the aux electric heater is working fine too.
 
Hi Dan,

I may be wrong, but I think that the heated mirrors work off the same fuse as for the heated window - so this would obviously rule out a fuse failure.

If I where you, I would switch the known working passenger mirror and the Drivers mirror and test them again; (though obviously stationary :D).

This will at least eliminate either a fault with the wiring or a circuit failure within the housing of the glass itself. Replacement glass, (if necessary), is readily available from VAGParts.

Cheers,

Darren
 
Yeah.

I finally got round to fitting my Audi ones over christmas, but again the drivers side one doesn't work.

I put a multimeter across the wires and both sides have current (the passenger side more than the drivers side)

Does it matter which way the wires are attached or is it just a case of the circuit is complete which ever way you connect the pins?

Anyone any suggestions?

I've discounted the fuse element as the rear window works and the passenger one works. or is there a seperate fuse fort he drivers side?
 
Hi all - got exactly the same issue on my S4 - Voltage to mirrors, rear screen works etc etc etc

Guess changing the glass is the next step as the little heated line down the mirror looks slightly corroded at the bottom - this could be the issue?
 
The procedure for popping out the mirror glass is, to put it full tilt inwards on the mirror and gentlely get your fingers behind the glass and it will pop out.

Mine did, don't whatever you do use a screw driver to lever it out as you will probably crack the glass in doing so.

Has nobody got a solution to this? The mirror not working i mean.
 
Thanks. Maybe the contacts/wiring within the glass itself degrade? Maybe just a whole new glass unit would make it work?
 
If the other side works, swap the glass to see if the fault goes with the glass, or stays on the same side. If it stays, then headscratch time, if it follows the glass, then it's new mirror time!

Cheers,

Mike
 
Thanks i hadn't thought of that.

I was going to take a battery and make a circuit to see if that worked, but it would be just as easy to try the mirror on the passenger side.
