Its located in the center on top of the a/c heater housing behind the dash and you can see it if you remove the glove box..
Book time for replacement is 1.5 hours...............
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.
A common cause for this is a burned out blower resistor. Tech JK --------------------------
Remove the glove box. The Blower Motor Resistor is on top of of the large black hvac housing. It is held by 2 - 7mm hex head screws. Very hard to get your hand in there to remove them. Connector is on top.
Under the hood, on the passenger side of firewall, near the blower motor.
on the blower houseing beside the blower motor
There are currently no recalls for the 99 Chevy Tahoe.
A bad heater blower motor resistor would effect one or more blower speeds other than high.
