Side mirror heaters.....One faster then the other?

maybe because the wires are shorter going to the drivers side

BrandonClaps, do you mean that one mirror defrosts faster than the other?

Yea, driver side defrosts quicker (same amount of fog on each mirror)

the longer the wire the more power is lost

In theory this is quite possibe. The heating elements on the mirrors are resistive loads, and their performance is directly related to the power provided.

There's resistance in the wire, which may create slight voltage drop given the increased distance, putting slightly less power to the passenger side mirror heater.

Not sure this is the cause though. Maybe the passenger mirror had less fog on it to begin with!

Yes, I have! I've been wondering whether I'm crazy! It's not a very noticeable difference - but it's there... Don't know if I should even say anything about it at 10K service...
