My honda SM4's blower fan motor has a resistance of 0.8 ?, & mostly us
asted as heat by these resistors which presumably have a total resistance o
In Dec'12 I noticed a Mercedes 350 has the same problem ( like cheaper cars
have ) of heat inside users' space when aircon is off, i.e. no buck conver
ter is used to reduce blower fan motor's voltage, so these resistors heat u
p this space even after aircon is switched off.
Does any car maker use a buck converter to reduce this voltage ? Does any1
know where I can buy a buck converter with easily switchable output voltag
these wasteful resistors ?
