Here's a thought...engine thermostat stuck open?  Here's why...if it
is, coolant will be quite cool at any decent speed when it's cold
out, until you start to go up a hill, and the coolant jumps in temp.

Do you remember off-hand if the heat cycles were when you were going
uphill/accelerating?  Where was the coolant gauge during this?  Did
cranking it up to "HI" change the behavior?

Also note that "bilev" puts out cooler air from the dash than it does
from other vents.
