In order to replace the evaporator, the HVAC unit behind the dash needs to come out so I suspect he missed a connector or it is not fully connected.

The only way to find this out is to check voltage coming into the module behind the dash. There are a number of power wires and if the connector is loose or off then the unit will not come on.
