What could it be when you have no air and no heat. Blower just quit working. How difficult is it to replace the blower?
Thank you.

No air and no heat or air and heat but just no means to disburse the treated air?

Blower motors can fail, I've had to replace a couple (under warranty, so I can't comment on how difficult)

Just driving and air quit working. switched to heat to see if any air was working. Nothing, not the defrosters, vents, or feet.

I'm still not sure I get this - there's two parts to the system:
1 Heating/cooling the air
2 Moving the air around the vehicle

It sounds like 2 has failed but has 1 as well? If 1 works but not 2, you should still feel warm or cold air at the vents, just no pressure behind it

I feel nothing. No air at all whether I have it on heat or air or just outside air. Absolutely no air flow. Is this my blower?

Doesn't sound like the blower. Even with the blower off, you should get a good airflow from the vents at highway speeds. I wonder if your control system has shut down. Does your car have an automatic climate control?

No. The fan or blower was making a rumbling noise before it quit.
