The hiss is from the refrigerant in the A/C system equilizing in the hoses
and evaporator. It proves nothing about whether the blower fan is working.
Please confirm, the problem is that the blower fan is not blowing air
nomatter whether you are on heat or A/C.
I am not familar with late model Tarui (but then I do not know which year
Taurus you are working on - do I). However, generally Ford locates the fan
speed control resistors in the A/C plenum, so I would look in that area. You
can always trace the wires from the blower motor back to the fan speed
control ressitor assembly. Or, maybe you should get a repair manual. You
could also purchase a 3 day suspscription from the Motorcraft Website that
will give you access to the Taurus repair manual (see
http://www.motorcraftservice.com/vdi...il/default.asp ). And in the
recent past, some guy posted links to Ford repair manual CDs on line (
http://www.fordcds.com/ ) for free (probably not legal). In addition to the
resistor pack, there are also relays in the system that could be the source
of your problem (relays #3 and #28 in the underdash fue panel for a 2000
Taurus for instance). What year Taurus are you working on? Does it have
automatic tempeature control?
