Umm, the last comment on this thread prior to yours is 9 years old, but thanks for sharing.so my rsx's heater stop working my ac works but when i turn the thermo to hot i get no hot air. I disconnected both hoses that connect to the heater core on the firewall, make sure ur heater valve is on the on position. Buy some core flush or radiator flush and flush out your heater corre and change your cabin filters and it should work. thats how i got my heater to work.
