Behind the glove box
on the blower houseing beside the blower motor
Blown fuse, bad blower motor switch, blower motor itself, or a defective blower motor resistor pack.
The blower motor is drawing to many amps, replace the blower motor.
behind the steering wheel
The blower switch is the knob you turn on the heater control in the dashboard. If you are talking about the blower motor resistor, it is located in the passenger's foot well area, mounted in the heater box.
Its acually blower motor and it is located under the passenger dash. real easy to get to and the blower motor relay is in the same area. Might want to check that first because that's what usually goes. Thanks, hope this helps
Just above and next to the kick panel on the passenger side.
Remove the wiring harness from the back of your 1999 Chevy Monte Carlo blower motor. Remove the blower motor retaining bolts. Remove the fan on the front of the blower motor. Reverse the process to install the new blower motor.
On the passengers side under the glovebox near the side kick panel.........
Blown fuse, bad motor, bad blower motor switch, or a defective Blower Motor Resistor Pack.
99% of the time, the blower motor relay, or resistor block,will be bad if the fan motor only works on high speed.
Check to see if you are getting power and ground to the blower motor - if so blower motor is bad. If no power possibly fan switch or selector switch Also check the blower motor resistor, found in heater plenum.
Under the hood, on the passenger side of firewall, near the blower motor.
It should be located under the dash above the passenger's foot area next to the blower motor. Unplug the harness and remove the two screws holding it in place.
1) Check the blower motor, make sure it is not making any weird noises.2) Check the blower motor resistor, its located next to the motor. It is what controls the lower speeds of the motor. You can try to find one at the junkyard.
Your blower motor is going out. Be prepared to replace it soon or it will just quit working all together.
Under the hood on the evaporator case.
99 TRNS PORT BLOWER RESISTOROn my 98 it is under the dash on the passenger side, you have to remove the glove box, and the blower motor it is behind the blower motor with 3 crew holding it in
Why does my 99 silverado have no heat and the ac fuses look good and blower motot works great
The front blower should have a resister to change the speeds. It is usually mounted close to or on the back of the blower motor.
Check the following................ 1. Power and ground to the blower motor. 2. Blower resister. 3. Blower switch.
A bad heater blower motor resistor would effect one or more blower speeds other than high.
Check the blower resister and then check the blower motor switch..
