Do you leave it parked so the sun faces it?

JK.

The mirrors have a built in defrost/defogger. i'm not sure if that makes it hot, but I'm pretty sure it does. Not sure if it is on all the time either.

yeah, It's really problem, Can you check out with your IS. Is Yours turn on the heat all the time ?

mine used to be like that, too. haven't checked lately, though. it's for defrosting and i heard it is supposed to be always on

The 2001 IS heated mirrors are on all the time. For 2002, they only go on with the defroster or something like that.

8) Many thanks, bro. I feel better now. It means there's no trouble with the wire like the guy in service centre told me. God blesses him

I concur.
Back in the days, when only 2001 model was available, some did a mod where a switch would turn on/off the heated mirrors.
