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, Jan van de Wouw Thinking Different...
