my 1999 acura TL, 3.2L v6 temp gauge says its running hot but I have no heat?

thermostat has been replaced. did it this morning. it was really easy. still no difference. the car seems to get hot fast but I have no heat. also, it seems that the cooling fans only turn on if a) a/c is on. or b) right after I turn the car OFF. I don't understand what the problem is. is there still air in the system? I feel like I got it all out but... Did the heater core go? Maybe there is an obstruction somewhere. I NEED HELP!!! Please email after 500pm unex3007@yahoo.com need tis car fixed asap! Help!

What was the outcome on resolving this issue? I am having the same issue with my 99 3.2TL.
