that's what it does when you remote start. That's the whole reason for remote starting, to cool the truck down in the summer and warm it up in the winter. Why would you want to remote start your truck and not have the a/c on. Do you have that much money you just like to let your truck idle away gas?

 

Well I start it about a minute before I get in it while I'm putting on my shoes. For example it is only 7c (44f) this morning. There is no need for heat or ac at that temp. I'm not one for hoping in, starting and driving away. I like to idle it for a minute or two.

 

LOL good use of auto start.

 

I do this as well, probably use it more than turn key starting.

 

when you use remote start the ac or heater should come on full if you have atc when you put in the key and turn it on it should go to what ever you have it set to

 

Not sure If you guys figured this out yet but you have to connect all the accesory wires and ign 2 wires with diodes to the one brain input acc wire....ALso to get the headlights to work you use some resistance...not sure on the amounts for specific years...But I'll let you know asap.

Again if its already been answered sorry lol Im tired
