I run a komatsu pc220 and the heat isnt working the radiator hose is reading a temp with a heat gun at 117 and under the cab the hoses are reading at anywheres from 147 to 152 the fan is working and pushing the recycled air through the cab through the filter behind the seats and the outside air but the air coming out of the vent behind the seat is at 85 but there is no power behind it, it just registers on a heat gun the air from the filter is anywheres from 39-41 degrees. and there is nothing coming out of the vents for the defrost or the vent that points at the operator.
