BAD FUSE SOUNDS NUTS BUT IT IS?
Common causes, blower motor resistor, blower motor, wiring or controls
Climate control blower motor was the fix. The part cost 441 dollars.
The blower motor is shot, if it doesnt come out of the vents, feet, windshield, anywhere, its the blower motor, take it in and get it fixed before winter comes, your heated leather seats wont keep you warm enough bud.
If it's a fan speed issue check the blower motor resistor & the blower motor. Check the plugs at the resistor and blower motor for burn marks also.
Could be,Blown fuse,Bad blower motor,Bad blower motor switch,Bad blower motor speed resistor,
Should under dash on firwall near blower motor.
where is resistor pack on 2010 impala lt 6 cylinder 3.5 motor
Blower motor control relay under dash behind blower motor is bad or has water in it from cabin filter port.
Same problem on mine...I had the blower motor module replaced and it works great.
Blower motor bad. Blower resistor bad. Switch bad. Fuse blown.
Probably the control unit mounted underneath the relays by the firewall. Get a used one somewhere, but get a new blower (parts store item) to go with it. That might save you from having to buy an other controller.
Check for loose wire connections also Defective blower motor or resistor pack. Blown fuse or defective blower motor switch.
