I'm going to go on a limb here and assume that, if you can drive a 379, you know how to work the HVAC controls already. So I'm guessing you've done this and have no heat. Feel free to correct me if I'm wrong here - you can PM me or send an email to the address on my bio page if this in incorrect. Look under the hood, particularly on the right (passenger) side of the vehicle. Coming out of the block, there will be coolant lines which will go to the heater core under the dash (depending on model year, they may or may not go through a heater control valve first). At some point on these lines, you may find some simple cut off valves which cut off the flow of coolant to the radiator core(s). Ensure that these are open. If they're not, move them to the open position.
