Hi everyone, My heater Stop working last night when I was driving home, everything looks working fine but not hot air coming out the vents.

The blower is working
I check the cable that switch from cold to hot, and the valve is working right
The hoses connected to the valve are hot

It was working right and stop working just like that

I notice when I push the defrost mode the a/c comes one ( green light ) so I puch it to turn it off, but still not hot air coming out.

If this happened to someone and can give me a suggestion will be great! Thanks.

your coolant temp gauge taking forever to warm up? Last time you changed the thermostat?

Yes bove of them are hot

Coolant level is ok, and yes the RED **** is on red.

I will say it take the normal time to heat up, the arrow is always a little under the midlle of the gauge, I change the radiator a year ago, Thermostat not done yet, I was considering that as a reason but the car temp is allways normal.

Thanks for the Image, I am going to check that right now.
I have one question, when the valve cable is pulled it moves the air mix at the same time or it work apart.?

viequense

Ok, thanks a lot to everyone
Following the diagram that HondaPartsHero Post,
I get under the dash and find out tha the tempeture **** was moving the valve cable right but it has 1 white shifter that open and close the vent to control cold or hot air that was not on the guide it was stock on one position, as soon as I fix it, hot air came out of the vents.

Thanks a lot to everyone!
