I can't turn it off. It won't let me get to the original settings menu I turned on talkback on the alcatel one touch phone...

When I start my truck it starts and immediately stops. What would cause this?

It's the airflow flapper is on heat. When the temp control is on hot the flapper opens the air flow to the heater core. Check temp control and make sure it didn't accidently get put on hot. If thats not it then the vacuum hose may have became unplugged,
