Heater not blowing - '92 Cutlass Ciera

Hello,

Well, here's the situation- It is freezing cold (-30 C) and this morning my car would not start- I got a boost and now it's fine.

Now, it will start, but the heater is not blowing any air whatsoever, and neither is the A/C. And, of course, the car is overheating after driving it around the block.
There were also some problems about 2 years ago- the high setting would not blow any air, but it seemed to have resolved itself.

Is this a problem with the heater blower motor? Is there anything I can do to get it running? Is this a pricey issue to fix?

Thank you!!
Blower motor or resistor for lack of fan,

No heat and overheating is probably low coolant and you need to find out why if so. Some of these cars won't give you the blower until warmed up and low coolant would screw up that system,

I will check that out.
