In other words, I dialed in 82 degrees tonight, and it came out slightly warm. 85 was slightly warmer. Neither as hot as I believe it should be. Can you tweak anything on these systems?

 

The temperature setting is not the temperature of the air that comes out of the vents. It is the temperature as what you are aiming to get the cabin to be.

 

Agreed. But this vehicle shoots out much colder air than my wifes 470. I wouldn't get warm very quickly when it gets much cooler outside. I'm thinking I may have an issue.

 

If its not getting hot very quickly you may have the radiator termistat stuck open. That's generally how they fail when they do go bad. I think its a relatively cheap repair on the LS .

 

Setting the vents to re-circulate the air will help it to warm up faster.

If it takes more than a couple of minutes to start pumping out warm air,there is likely a heater issue,as Jabberwock suggested.
