How do i replace the fan motor and where is it located?

Wow, 3 fans in car and we get to guess,why.?
first what are you doing.? (guess,i want cab heat to blow?)
parked key off?
hot engine wanting heat from HVAC vents
? what?
or under hood and radiator fans are dead but overheated.

HVAC is a blower fan,or blower, the fuse is called blow.
does blower sound ok on high???? SouND?
if yes (if no controls are bad)
is air flow weak. yes. that is dampers failing
both the blower and dampers and heater core are in the center
tor right(usa) of dash in hugh black box.
first check fuses
then scan the car. yes, you must scan it see HVAC errors
or its all just a waste of time..

some models have filter and packed up ,my block air flow
some have it others dont,. not fun finding it.
most are behind glove box (after removal)
