That is an interesting one. I think I would start by checking to make sure there isn't a problem with the factory alarm system. If it is good, then I would check the ignition switch itself.

Already checked it and the remote starts truck fine the manufacture says that it is working fine that it is a truck problem.
Can when truck is running if I use comand start again it will start up the heat till truck breakes are applied.

Just to add to this one are you saying the inside blower motor works fine and when you hit the brakes the blower motor shuts off?If thats the case I would say the brake lights have a bad ground and when you step on the brakes its some how stealing the ground from the blower motor.

Yes the blower works as long as I start truck with the comand start but as soon as I step on break to put truck in gear the blower stops working.

Then I would check the ground to the brake lights and the blower motor.
