Buick Century Problem Report
Buick Century Heater only works on high
When the heater only works on high, the most common problem is a blower motor resistor. The correct repair is to replace it with a new resistor.
My heater only worked on high before, and when I would turn it on it would make a horrible screeching sound. The thermostat turned out to be bad, once this was replaced, it seems to work a lot better. - sarahfo
