strange heater behavior

I recently fixed my climate control system on my 82 300d and got all the flaps working except for the center vents (due to a vacuum pod issue that will be addressed later) and at first run, everything was fine. (Thanks to all that helped me with that) However, once the cabin gets up to temperature, the heat slowly dwindles away, and then the vents start blowing cold air until it is cold in the cabin, then the heat comes back on. I've heard that there is an outside temperature sensor on some of these cars, and with my newly working vents/flaps, I'm pretty sure that this is to blame. Does anyone know where it is/how I can test it/bypass it? The automatic heat worked great before I got the vents to blow anything but defrost, and now I'm chasing my tail. Anybody out there got the same problem? Guess I should have left well enough alone once I had the heat back on. Vents be damned.
