First of all congratulations on buying a DeLorean again.
As to your question;
most people don't realise that there are in fact two 
separate streams of coolant:
- One controlled by the thermostat, going through the 
engine and then to the radiator up front that provides 
engine cooling.
- The other is always circulating EXCEPT when you have 
the Mode Switch set to Max. in that case a vacuum is 
supplied to the special valve by the engine that cuts 
the coolant flow through the heater core.

If your mode switch is connected wrong or if this valve is 
broken you won't get any hot coolant to the heater core 
so there is no way to heat up the car...

Another possibility is that the cable connecting to the 
TEMP-knob has broken or come loose and the temp-flap 
in the AC-ducting is stuck in the cold-position. 
Try to listen for the flap's movement whan you're turning 
the knob without anything else on, if you can't hear it 
moving that's probably your problem.

Good luck,
