The lines of the A/C under the hood are freezing up at the start of the vehicle and not blowing inside.

Good afternoon,

Do you mean the blower motor is not working at all?

I attached the location for you of the blower motor. We will need to do some voltage checks to determine the failure.

Do you have a test light or voltmeter to do some checks? It could be the motor or the resistor.

it may be the blower motor that is not working, but, the lines that are on top of engine and seen once hood is open are freezing with the start of the vehicle and the control center/panel is also not working at all.

Okay, the lines are icing up from the blower motor not working. If there is no air flow across the evaporator, the lines will freeze.

Let me know when you want to do some voltage checks.
