I have no clue what the problem is. Last winter when after I let my car warm up I went in to turn on the heat. The problem is cold air came out, then a few weeks ago i turned on the ac because it was hot outside and hot air came out. It seems like its just blowing in air from the outside and not converting the temperature but thats only a guess. anybody know the problem

I don't have entirely too much info. But when you turn the A/C on does the compressor/clutch engage? That's where I'd start with the A/C. As far as heat goes, I've never had a problem like that on any car.

Check the heater hoses near the passenger side firewall. There's a heater bypass valve that sometimes gets dirty and binds, try cleaning and lubing the cable to it. If that doesn't help, then run the climate control's self diagnostic feature for faults. It may be the air mix diverter control linkage. Also check the fuses.

Ok I will check those, thanks for the options because I was lost.

Would my transmission fluid temperature sensor have anything to do with the problem

^^ No.

I had the wiring harness for the controller burn out on mine. Apparently it's known problem and Acura makes a patch harness for it.

if no control of fan or no ac operation try the connector prob first

If no control of temp but control of fan- look in diy for Mix Motor and lube that valve that controls water flow thru the heater core, near firewall
