Hi Brian, What you are explaining to me is that the fan will not go on med or low, but just runs on high. Check the connections behind fan control switch. If a wires is dirty or correded and making bad connection the fan could work on high alone or the switch itself could be bad. Check the wires first. The same if the wire for the high was not connecting then the fan would work on low or med. Put the fan control on med and I found moving the wire harness by the switch behind the dash, around some usually will help tell if there is a bad connection. If the fan speed changes then you have found the problem.
