Why do i have no heat in my 1998 ford ranger pickup?

Answer 1

have you turned on the switch? If so here are somethings that you can check...

1. blend door actuator

2. thermostat

3. radiator fluid level and color (should be green)

4. heater core.

Check those things!

The blend door actuator works a flap that sends hot air from the heater core to the passenger compartment or to the defroster, it will be located under the dash on the passenger side. It works by vacuum or a small electric motor.

The thermostat is located at the engine end termination of the large hose running from the radiator to the engine block. The gooseneck the hose attaches to is usually held by two bolts and the thermostat is inside this housing. The thermostat can stick and cause overheating and loss of heat in the heater.

The heater core itself can leak, which in many cars will show up on the floor on the passenger side of your car. Another indication of leaks would be steam coming from the vents. It also has to be taken out from under the dash on the passenger side.

It is a good idea to have your system flushed if you notice that the water in the radiator is rusty or orange colored. The water should have coolant/antifreeze in it which normally would give it a green color.
