I have a 95 Bronco XLT 5.0 302. Winter is coming and I have no heat. The blower works fine, just no heat. I checked pretty much everything. Both of the heater core hoses feel hot. I even took off both of the hoses and flushed water in the supply line and the water came out of the return line. Does this mean that the heater core is working or not? I really don't know what the problem could be, unless its in the actual controls in the vehicle. Please someone help. Thanks
