Question about 2000 Lincoln Continental
Press OFF and FLOOR at the same time, and immediately press AUTO to activate the self diagnostics test mode, and post the code (work for 2001 TC). Also could check this ARTICLE.
Keep in mind that in the auto mode your fan goes up and down according to inside temp... I like to use the fan speed instead i just turn the fan speed dial that cuts off the auto mode. So, the blower speed constantly fluctuates enough to notice? Does it cut out or just change speeds? When on "Auto" the fan speed can change considerably.
The blower motor speed control is solid state, as well as the control head, no relays to mess with. If there is a constant shifting of blower speed, the chances are really good the control head is commanding it to change. The only thing I have ever seen the blower motor speed controller do when faulty is either not let the fan work at all, or keep the fan running all the time.
To be honest, in the shop, I would throw another control head in it, see what happens and diagnose from there (I know that doesn't help). Could be any number of intermittent faulty sensors, temp, sunload etc. Possible bad ground.
Keep us updated.

HI and welcome to FixYa!
As a first course of action I suggest that you remove the positive battery of the car and let it sit for atleast 5mins. then reconnect it again. This can give a jumpstart on the temperature control.
Hope this helps and thank you for using FixYa! Have a good one!
