Blower motor sounds shot. It is behind the glove box. Easy fix if what went out is the blower. Can you turn it on all the way to high and get air? If so then it is the blower motor.

Check all your fuses first. I believe a bad blower motor will still blow air on the high air setting.

You're on the right track. The acc. wire at the ignition switch tends to get hot and cooks the terminal at the ignition switch.

Sounds like you found the issue. Easy fix, just drop the glove box door and it sould be right behind there. Do a little google searching and you will find a few write ups on how to replace it. Let us know how it works when you are done for the benefit of other members.
