1. How to keep the heat always turn on. In fact I always keep running the heat. But when you see my car at night I keep the heat on. So in the morning when I run the car. Then the heat off.

 

I'm not following.

Whatever setting you left before the car was turned off will stay in the same setting when you turn on the car. In order for the heater to work, the engine needs to warm up the coolant. It's not instant heat.

 

 

I get that. Are you expecting the heat to come on when you first start the car up in the morning?

 

 

The heater in the GS is based off the cooling system. If the coolant\engine is cold, you won't have heat for several mins. The car needs to run for a while to heat up the coolant to provide heat in the car. Does the heat work after you drive around?

The only car that has instant heat is probably an electric car like a Telsa or a hybrid like Prius that has an electric heating element.
