Living in New England it's pretty damned cold right now, even more so as my=
 heater just quit!!!

I thought it was the prograqmmer module and picked one up from Chris Semple=
 today (thanks Chris - star as usual)

Turns out it's not and I am beginning to fear it is the blower motor itself=
, which I will try to check tomorrow, in the meantime I noticed something o=
dd and I was wondering if anyone knew what it was;

1=2E heater blower does not blow at all on any settings, I pop the cover on=
 the blower controller (the resistorthing by the windscren wipers.) there a=
re 3 connections - a sealed 6 or 7 way plug, the G connector and the H (ear=
th I beieve from memory). I followed the bentley problem tracking and earth=
ed termional G with no change - blower not running.

Then I noticed the rad fan was running at speed 1 whenever the ignition was=
 on, when I pull off the 6 way connector on the blower controller, the rad =
fan stops running, plug it back in, it comes on again after about 0.5 to 1s=
econds.

Thats the wierd thing - is this a normal sign of a done for blower motor?

I also thought it could be the temp sender by cyl 1 that stops the fan comi=
ng on at cold coolant temps - but it seems OK ( think)

Any advice greatfully recieved as I am freezing my arse off (heater in seat=
, elemnt connection between back and seat is busted - any good Ideas on fix=
ing that appreciated too as I soldered a wire inbetween and it only lasted =
a few  months)
Hopefully yours
