It was the blower fan resistor. No resistor to be sold separately at any local supplier. I got a used blower fan with the resistor from a totaled 13,000 km truck and solved the problem. Nobody local had a new fan unit in stock either but I found that ultra low mileage used one from an insurance vehicle salvage operation.
