Lots of dew on the outside mirrors these mornings in the 6ix, but they are slow to unfog.
Temp probably 18C or 65F.

Even after 5 minutes driving they are still completely covered with moisture and downright useless. Was a little bit dangerous this morning when trying to make lane changes. Sigh.

 

Hope this helps!

 

Yeah, so it looks like it's on 25%, when I really need it to be 100%. I think my BMW had it always on.
My wipers are always set for auto on, so that doesn't help after the first start up swipe takes place.

Thanks!

 

@Whitetardis. Good info, thanks.

 

The mornings have been cool, in high 40s with lots of condensation on glass and mirrors. I have left wipers on, following advice here. It takes a squirt or two of washer fluid to keep glass wet, but within two blocks mirrors clear. Works well now, as it's about 5 blocks before I get on interstate and need the mirrors clear. Before mirrors wouldn't clear in time. Thanks again!
