CHECK THE BLOWER HOUSING. IT SITS INSIDE THE HOUSING AND IS SECURED BY SCREWS ON TOP OF THE BLOWER HOUSING.
Under the hood to the left of the blower motor mounted in the housing on the firewall...
Resistor is located behind the blower motor assembly.
It may be the resistor pack along the firewall under the fuse cover somewhere. This controls the speed of the fan.
check for voltage at the blower motor on all settings. if no voltage check the blower motor resistor or relay. if it has a resistor it will be right beside the blower motor, if it has a relay it will be the relay on the firewall under the hood.it will probably have a purple,orange,blue,and black wires.
The blower motor resistor is located just above the blower motor under the hood. It should have an electrical connector plugged into it and some screws holding it in place.
Should be at the passenger side firewall
Check for a bad blower resistor at blower motor
its behind the blower motor under the passenger side of dash
the resistor is directly behind the blower motor under the dash
Blower motor fuse is blown. Blower motor resistor burned out. Blower motor switch bad. Blower motor bad.
Please email me a photo of where the blower motor resistor is and how to change it. Thanks, Michael. By the way I want it for a 2000 Sunfire not a Grand Am.
blower motor resistor is bad
