Remove the glove box and look way back under the air box
Answer:Just had to look for mine today... the heater blower is under the passenger side of the dash under the glove box. You will see two 7mm screws holding the black plastic cover over the heater... remove these two screws and pull down on the cover to reveal the heater blower... in front of the blower and to the left you will see a cable with 5-6 wires plugged into a connector -- that is part of the heater housing. Two screws hold this assembly (heater resistor) to the case. remove the screws...remove the resistor assembly. There is a spring clip that holds the cable connector in. Spring it out a little and the connector will remove easily...there is also a purple/beige wire assembly that plugs into the heater motor... this one is a little harder. I had to work with a mirror. It also has a clip restraint. This one you press IN to release the the cable will come out... or you can just remove the small circular cover with a 5mm socket...it's much easier than trying to hold a mirror and remove the clip at the same time
This item can be purchased at Advance for less than the dealer price...
Its located on the passengers side behind the glove box right next to the blower motor......
it is behind the right plastic panel in the cargo area
behind the glove box that is where mine is on a 1996 Tahoe
On a 2004 Chevy Tahoe, the blower motor resistor is typically located under the dashboard on the passenger side, near the blower motor itself. It is usually mounted to the HVAC housing and can be accessed by removing the lower dashboard panel. Make sure to disconnect the battery before attempting to replace it to avoid any electrical issues.
In a 1996 Chevy Tahoe 4x4, the blower motor resistor is typically located under the dashboard on the passenger side, near the blower motor itself. It is mounted to the HVAC housing and may be accessed by removing the lower dash panel. To replace it, you may need to disconnect the electrical connector and remove the screws securing the resistor in place.
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...............
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.
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.
.4 with a/c add .1 if equipped with hush panels
The Heater/Blower Relay is on the blower motor housing under the dash in the passenger compartment on 1999-2002 models
Check the blower fuse located in the hood. It's a 40 amp fuse. Marked blower on the map
If you mean the fan works on high only it's the blower motor resistor.
