RE: 91 200qw: climate control fan

[Aleksander Mierzwa <alex@matrix.com.pl>]

There are two possibilities:
1) The multi-function temp switch, as you suspect it. Find out which
wire is connected to the low temp switch (sorry - no help on 91 200) and
short it. If the blower runs, you have found the problem.
2) On my 5K the blower motor sometimes seizes at low temperatures. The
symptoms are similar to yours. If I hit the pothole, slam the door or
exit the car and hit the firewall it starts to work. I know all it needs
is new brushes and a lube... too many things to fix, too little time :-(
