It could be a coincidence, but a common issue in our cars is an electrical connector that is located in the driver's door protective accordian covering, located near the door hinge. One of the wires going into the connector can come loose and short out against ground or other wires, causing the issues you describe. I'd check that out, first and if that isn't the problem, you might want to consider taking your car to a different Corvette specialty sho - one that is recommended by the locals.

Good luck!
