Fan will be under dash on passengers side , Removing glove box might be needed, Gm also uses a blower resister ro control fan speeds. First check your fuse and then check and make sure your getting 12 volts to the terminal at the blower, You could have a blown fuse, a bad switch, or a bad resister , if your getting voltage to blower motor then most likely it will be the motor. These are not to difficult to change. I hope this helps, please be aware I can only guess at what the problem is from my past experience.

SOURCE: Buick Century wipers out of sync
You could also see if the bolts holding the wipers on came loose from the snow and ice. Pop the cover off, loosen and straighten the wipers where they should be and tighten.

The linear actuator that regulates the blend of air between hot and cold was broken and needed to be replaced. That was my suspicion. Fuses were all good. Relays were all good. Compressor pump cycled. Freon was "proper". Dealership only charged about $400 in parts and labor to confirm my guess.

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

Could be a bad control switch, relay or connection and ground at motor itself. Since it's intermittent, check voltages when it's working, then again when it's not. Wherever voltage stops, that's what you need to replace. Don't wait on this...when completely inoperative it gets much harder to find the problem!
