So winter's in the country and I noticed that the passenger side mirror defrosts nicely but the driver side doesn't. Mirror on that side broken, right?
Swapped the two around, sure enough, the driver side works on the wires of the passenger. Took some readings with a voltage meter, 14.4v on the passenger side, nada on the driver's side.

So I'm a bit stumped, I can't see any damage to the wiring coming out at the driver side.

Is there anybody who could tell me what I can check? Are there fuses I can check?

Cheers guys
