No heat

Hey I have a 93 accord and just recently lost the heat. The rad is still full. When I was driving heard some raddling then my heat dropped down and my temp guage dropped down to cold. Any ideas im freezing in a Canadian winter.

As far as I know the heater control valve is in the engine bay. When you operate the temperature knob you should see some movement in the engine bay. I would start with with this.

Good luck,

Sam
