In Reply to: "Defroster button" --How mine works (more) posted by CFL on May 10, 1999 at 14:49:13:
I meant front windshield defogger.
: At least this is how I understand it works. My car is a 5/94
: production date 95 M3. The heated mirrors will turn on when I
: use the *rear* defrost button. I'm not sure what the _front_ defrost
: button is on a 98, does it activate the A/C to get rid of condensation?
: Then again I have round dials the way God intended them to be,
: not the fancy schmancy automatic climate controls and doodads
: that you newer M3's have (grin). My mirrors feel warm to the touch
: when they're on, it's nice because it will dry the rain droplets and the
: outside temp is nowhere near the 37 degree mark.
: Also as far as I know what happens at 37 F is the windshield washer
: nozzles begin to heat up. That's what the sensor on your right
: brake duct is for. The one on the left brake duct is to indicate
: outside temperature on the check control panel. My car has the
: check control/outside temperature/clock panel not a full OBC like
: the 96+ cars have.
