Question about 2005 Buick Century
Blower control fan inside car was running on hogh only and now its now working at all.
Usually this is from a burned up blower motor resistor. Not very expensive to replace, but can be a pain to get to. I do not think it is that bad on the 05 Buick though. It should be in the bottom of the AC/ Heater box under the passenger side of the dash, like under the glove box area. pull the lower trim panel under the passenger side of the dash and there should be a wire connector going right into the bottom of the heater box. unplug the wire and there should be 2, 7mm if I am not mistaken, screws holding the resistor block into the heater box.

A very common solution here is replacement of the blower motor resistor. The resistor when they break do one of two things.
A. work only on high
B. dont work.
This item is located on passanger side under dash and is usually held in with two small bolts on either side with an electrical connector seperating the mounting screws. It is mounted right in the air box. I replace at least one of these a week in my shop very common item.

The blower motor control module needs to be replaced, that will solve the problem. The module is underneath the hood on the firewall in the back. It has 2- 6mm screws. Unplug it, pull it out, put the other one back in. Plug it in. This is common for this model buick.

most likely when you replaced coolant line and refilled rad the system was not bled properly.
fill the system with 50/50 again and top up the reservoir. run the engine to 2000 rpm and look at temp gauge . it should rise to middle and drop to low this means t stat opend and air is out now let engine idle and top up coolant. good luck

If the thermostat is not opening then the engine heats up. So I would replace that first and then see about the fans not turning.
Hope this helps
