Heat not coming on with remote start

[roshambo14]

I have a 2012 LTZ Tahoe, and since it's turned cold a few mornings this fall already I have used remote start. The problem is that it blows air, but its cold air. When I put the key in and turn it on, the engine show's its up to temp. I drive away and a block later, warm air is coming out of the vents. I've checked to make sure its set to a temperature that is warm. I have it set at 72. It worked last winter. Any ideas on what could possibly be wrong? Thanks in advance.

Do your heated seat come on with remote start?

The desired a/c or heat has to be running before the truck is turned off. The heated seats have a threshold that they turn on at or the same thing of turning them on before you go turn off the truck.
