easy we love these,
year, car, and model, and actual accurate , symptoms.
i must assume it runs on high ,
a key factor.
my guess is 4 = max. or high.
most cars high is bypass mode, (direct fan drive)
so tells you that the speed reduction part is DOA. in part or more...
on most cars this is called the fan resistor block.
ill look up that in my USA FSM and see. now.
ok with or without climate control options,
i roll dice and land on none.
this car does have the fan resistor block 3 speeds (resistors) and dirct drive for 4 total speeds.
your resistor block is bad.
if your car has the V6 or advanced climate control option
all the above is Bull.
the CC options uses advance fan modulation to run the fans
PWM its called. and usaully never fails
the CC system has self test mode, its in the FSM , ill not attempt
to do that, pages, long.....
there you go,
Btw all this was at alldata.com and the free fsm.

my guess is, it's a non CC car.
