No interior cab heat. Position control switch does not activate all functions. Changed thermostat in engine. Line to heater core hot no heat or warmth in return line. Also the high speed setting does not work.
Last year the fan motor quite. Replaced but the high speed position on the switch does not work. Now there is no heat coming into the cab. The blower works up to the 3rd setting but I am unable to get the function switch to change position of where the air comes out to do more than 2 settings.
