Not knowing what all was done / touched in the engine bay and inside the vehicle (should not have needed to be touched aside from
driving the vehicle), it is difficult to say if it is related.
If the air is blowing and you are able to direct air up and down, but not getting warm, then it could be air in the system (in the heater
core) that needs to be bled out.
Is the heater panel manual control (knobs) or electronic (climatronic)?
