Ok my car has no heat right now. It did have heat before but all of sudden no heat. I thought it was my thermostat and I changed that but it's not. Still no heat.
I am guessing it may be the heater core because my AC was acting up strangely also.

The blower works fine... but only cool air comes out, I haven't changed my heater core yet but could it also be my climate control that's not working?

Any help please..?

 

heater core

 

The exact opposite thing happened to me. Only heat, no cool air. Thank God its winter.

 

can you hear the door moving? I would check that first. If honda used a heater core block off also check that.

 

on my jobs impala it had the same problem. It was low on coolant though.
Check to see if the door is moving though.

 

check to make sure the lever in the engine bay is moving with the climate control one. its located under the IM against the firewall!
