acura rsx power lock problem

Went to my vehicle today (2002 acura rsx) and the power locks would not work, the emergency break light is on even though the emergency brake is off, and the air is blowing hot. I was reading some blogs online in which other people had all three problems occur to their rsx as well but they did not say how they fixed the problem. I check the air and lock fuses under the hood and they are fine. Do you know what the problem is and how I can fix it? Thanks!
