Hey i will answer my on question. If you are lookingat the fire wall under the hood lookto the left where the blower motor is just below and over to the right thanks for your help ha ha hope this helps some one down the line
Blower motor: remove the glove box and you will see the blower motor and blower resistor.
The blower motor resistor is located on the passenger side under the glove box. Left side. there is a cover on the blower motor. remve the cover, this is the resistor. there is an electrical plug there.
The blower resistor on a 1999 Chevy truck Z1500 is located behind the glove compartment. There is also a resistor on the firewall next to the blower motor itself.
there is a resistor that controls the speed and should be near the blower motor its called blower motor resistor
Attached to the blower motor under the passenger dash
Held in by two screws in a housing just to the left of the blower motor housing.
Inside dashboard in path of air that blower motor blows.
open glow box and take out computor and it is there on the side of blower motor
There is really no method to "check" the resistor, text by substitution.
it is underneith the passanger dash above the black panel under the dash behind the blower motor
replace blower motor resistor. It is under the passenger side foot well.
The blower motor is located in the same area as the resistor, it's held in with 3 screws. Removing them will allow the motor and wheel to drop down.
