behind the glove box that is where mine is on a 1996 Tahoe
Its located on the passengers side behind the glove box right next to the blower motor......
The blower motor resistor pack is accessed from inside the vehicle, not from the engine compartment. Exactly where it is I cannot say. Follow the wires from the blower motor and you will find it.
it is behind the right plastic panel in the cargo area
Right next to the blower motor
In a 1988 Chevy 2500, the blower motor resistor can be found on the passenger side. It usually is behind the glove box.
The blower resistor controls the speeds of the blower motor Hi-resistance lower motor speed Lo-resistance higher motor speed
I am pretty sure that a 97 and 99 are the same. On a 99 Tahoe the blower motor resistor pack is on top of the air box. Remove the glove compartment door, the blower itself will be on the right side. All the way to the far left on top of the air box there is a plug. Unplug and remove the 2 small screws. With some manipulation the resistor pack will lift out.
In the truck!
.4 with a/c add .1 if equipped with hush panels
Under the hood. In the blower motor harness connector.
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.
If you mean the fan works on high only it's the blower motor resistor.
