The buttons on my Tempmatic pushbutton unit (1987 2.3-16v) have no effect on the climate control. No matter what button is pushed, even the "O" (off) button, the fan stays on. Also, the other buttons have no effect in rerouting air to different vents (including the defrost setting). Note the following tidbits of info:

the pushbutton unit is new;
the switchover valve unit is new;
the feedback potentiometer and associated valve (on top of heater box beneath dashboard) are new;
I hear a clicking in the blower control switch (controls blower speed) as the blower turns off, then turns right back on again;

What could the problem be? A bad blower control switch? A bad blower motor resistor group? Something more or less obscure?
