Ford F-250 Heater Problem
Heater will not switch out of defrost. Auto hubs will not engage. buzzing noise under the dash when the heater and fan are set to off. Acts like a vacuum problem. Heater works 4 wheel seems to work with the hubs manually locked. What's wrong and how do I fix it? F-250 diesel. Happened once before, easy fix, dealer charged $250 and no parts.
