Automatic seat broken, How to manually adjust?

When vehicle warms up it just shuts down
The engine starts in "open loop" mode with factory default settings in the ECM. When it warms up, it goes to "closed loop" operation and relies on the O2 sensors to adjust timing, fuel, etc. Check for error codes (DTCs) using an OBDI code checker, or consider replacing the O2 sensors.

The heater blower works but we only get a small amount of air
I would say, check the engine coolant temperature, if that's okay, check water flow trough the heater core. If the coolant temperature is to low replace the thermostat. If the water flow is to low though the heater core, it must be partly blocked, and should be replaced.
