    Both sides of the thermostat housing are dead cold not even thinking about warming up when I put the heat on normally that keeps the engine running not now I have the heat on full blast fan on low everything is set to HI air conditioning is not into play and as is no defrost front or rear The car will sit there and not even come on I have to step on the gas or put it in gear? Usually when I put the heat on high first start in the morning the car has to run 20 minutes to get the heat where it's supposed to be I mean the ice engine. So now I'll call for heat from the multifunction display does not bring on the engine that must be some sort of a clue.
