Ralph, Since they were poking around in the vicinity of the heater box where your blower motor is located, I would take a look at the compressor cut out switch that's located on the heater box. It's a thermal switch with a capillary tube that extends into the heater/evaporator box.
If you look under the passenger side dash where your blower motor is located, just look to the left and you'll see a couple of wires going to what appears to be a block of fuzzy insulation like material. You can jumper or short these wires together to see if your compressor will engage. It's in series with the low pressure switch, I believe, so you'll need to be sure you have a fully charged system.
