Heat not working; 99 Honda Civic DX
I tried using "search" but it's acting funny right now, so I'll try later
BUT....car is a 99 Civic DX.
My heat doesn't work aka no hot air. The blower motor works - blows at all settings. I just replaced thermostat and put in new coolant. Car reaches normal operating temperature, but no heat - just cold air blowing out.
I checked the fuses/relays for resistance, they seem to be okay.
Any ideas? Coolant temp sensor, etc.?

had the same problem in my 93 ex, i disconnected the hoses going into the heater core under the hood by the firewall, ensured the heater valve waas functioning properly then flushed the core to make sure flow was going through the core once i flushed it with the water hose i left it full and connected the hoses and topped off cooling system with coolant and it blows hot all the time now. you might have build up in the core just flush it how i did.
