Asked by Feb 09, 2017 at 11:15 AM about the 2005 Buick Century

Question type: Maintenance & Repair

My heater/ac. The light comes on but no air comes out. I checked fluids my
coolant was low so I put more coolant in. Still not working. What could it be? My
blower motor? Vacuum?

If you have no air blowing out the vents then the blower motor is not working. But more than likely it would be the blower motor resistor that has gone bad. This makes the blower motor work.


No air means no blower motor. If it does not work on any setting, including high, then either the blower motor is not working or it has no power. While it's good you topped off the coolant, that wouldn't stop the blower motor from working. This might help. http://www.justanswer.com/buick/2efdg-2000-buick-century-blower-fan-stopped-working.html
