97 Ford Aspire replaced the radiator the coolant the thermostat heater core and water pump fuses temperature sensor still have no heat and temperature gauge still does not work what else is left?
Does the car have a control valve or does it adjust the heat by closing off the outside air? The valve if it has one would probably be under the hood in one of the heater hoses. If no valve, is the outside door closing? Control cable may be broken or have come loose on either end. I'm assuming the car does not overheat and the water is circulating. Get it warm and feel each hose where they connect to the heater core. If both equal, there has to be a door not closing somewhere. Too much outside air for it to heat up. Sometimes the simplest things are the hardest to find or see.
