The front heating & air unit will not blow anything when turned on. It used to come one sometimes but now it just stopped. I did get in the other day and it came on when I started the car and stayed on but when I got back in it would not come on. What should I do?

Hello, I'd start by checking the fuses. You also need to check that the fuse circuit is hot, use a testlite.

Htr/ac fuse in the fuse box, goes hot when you turn the key on.
Blower fuse in the power distribution center, under the hood, hot all the time. Go from there.
