I have no heat. Manual says it has to be a certain temperature outside before it will work. I need heat and defrost now. How do I get it to work?

look up online ambient air temp sensor and the mod of car and unplug it and see if that works assuming that it has climate control for the passenger compartment

I have a 2003 Rendezvous defroster works but the heater won't. I have changed the thermostat and flushed it twice and still no heat until I have driven it for almost an hour then a little bit of heat will start coming
