Problem Description and Possible Solution
The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.

My fan for the a/c just stopped working 2 days ago. It was completely fine on Friday and not turning on at all on Saturday. I checked the heat as well to determine if it was the a/c or the fan. The heat didn't come on either. So, I suspect it's the fan.
Could it be the Final Stage Unit/Resistor that I read about? Could it be a fuse? Is so, where do I look? I took it to a garage and they wanted $140 just to look at it because they said they need to diagnose the problem with a machine. I declined and turned to the internet for an alternate opinion.
Thank you in advance for any help.
My heater/Air conditioner blower has always blown intermittently, and at varying speeds. 3 days ago the blower stoped working altogether. I can still feel heat from the vents, but is not blowing out and causes quite a problem in the morning when the windows are foggy, will not defrost.
