I have a 2007 nissan altima. Everything was great till this winter.
when it is cold outside I warm the car up for several minutes before
driving. The car warms up fine just like usual (with in 3 to 5 min.).
but the blower will not come on for alot longer( you must drive car
with heat on high and vent on so air blows in from outside movement)
if car sits blower never come on, (only when cold out) (the colder the
longer blower takes to come on). The dealership mechanic told me that
it was an option as to not blow cold air into cabin. But. This takes
way to long and you must drive car before blower will start. When it is
above 50 degrees out then blower comes right on.
it seems to me that if what the dealership says is true then there has
to be some sort of sensor that tells the car that engine is warm and
to turn on blower. Dealership is a very long distance from where I live
and very expensive for me. I feel that the sensor(if there is one) must
be malfunctioning (partially). Also I feel it must be located some where
that is exposed to the air that passes from engine compartment to vents
in car(because driving with vent on and high heat eventually warms it
enough to come on). I may be totally off here, and end up taking to
dealership. But was hoping maybe I was on to something with sensor
idea or that maybe someone could help, either naming sensor or part,
give location of part, or tell me you way off base but. Here is a
solution. Any help or ideas on the problem would be greatly appreciated.

Get a scan done to check for trouble codes and if any fault with sensors are present, let us know the exact code.

I also had a 2007 Nissan Altima and so did a friend of ours. Both cars did the same thing you describe. It should be considered a safety issue and a forced recall ordered, because the windshield can not be defrosted due to the failure of the blower motor to actuate.

I liked the car.I HATED THE HEATER BLOWER MOTOR - The inconvenience of being cold with frosty windows led us to not buy another Nissan.

How is that a smart policy for an auto manufacturer. Fix the problem. Keep the customers. At least that' s what I would do.
