heater not working

[zoli]

Hello all,

My 'comfortron' system on my 1977 Caprice is working totally fine, except for the fact that it is blowing out strictly cold air all the time. At a shop they have come to the conclusion that my thermostat is working fine, and that there must be a connection issue between the dial (for changing the temperature) and this flap-thingy that opens or closes the air flow of the hot air into the cab. We think that the flap-thingy is either seized, or not getting an elextric signal that would tell it to open/close. In order to fix this, I was advised to take out the glove-box, as the components are behind it.

I have taken out my glove-box, but I don't know where to go from there. What my aim is to make sure that the flap is open all the time, so that when my A/C is on, it will blow hot air only. I don't know what this flap looks like, or where to look for it, but I have a feeling I'm not far from locating it.

Does anyone have any experience in this or have pictures that would help me out?

Many thanks,
-zoli

I was going to suggest the diverter valve, but you found it yourself!
