My car is not heating defrosting windows or putting heat into the car it’s just cold until miles and then he will start form but if I slow down and stop it will cut out again what is wrong with my car

Hello, it is very normal for your engine to not reach operating temperature for maybe five or 10 minutes after driving. Sitting and idling does not get you enough warmth from the engine to create heat for your interior. Certainly is happening faster than not remote-starting to begin the process, but it is not like you have a "heating element" that creates heat for the inside of the car -- you have to get the engine to operating temperature. If it is extremely cold outside, as it likely is in Colorado, then you will not get sufficient heat from your ventilation system until probably 10-20 minutes after driving. I don't know about 10-20 miles -- certainly it could be that your thermostat is opening prematurely and not allowing the engine to get to and maintain a proper operating temperature. You should see a local shop near you to measure the engine's temperature cold and see what the "warm up" cycle is like to get to proper operating temperature, which is sustained.
