SOURCE: Heater not blowing warm air. Thermostat has been

Check the water control valve behind the engine close to the firewall. This valve opens and closes to allow hot coolant to enter the heater core. It is usually connected to the heater controls with a cable. When you adjust the heater control for heat, a cable activated lever on the valve should move and allow coolant to move through the valve. The cable from the heater control can come loose from the lever, or the valve itself can become corroded and hard to move.

No biggy.The seat heater can be repaired by the dealership.Should not cost much because there are no parts just a reprogram of the drivers seat module.The blower motor is the blower motor resistor module.It is on the passengers side under the dash next to the blower motor.You should be able to do this yourself if you have a little mechanical experience.Hope this helps.Good luck.

Where is relay for heater glow plugs located


The relay is in easy view on the top of the motor, a little to the right side (passenger side). You will see two identical relays. One of them, the large battery cable goes to the intake air heater. The other relay is for your glow-plugs.

1994 F-250 Heater Core


Answer for a 1995 F250:

Remove the glove-box door. Behind that is the heater core cover on the interior, passenger side of the firewall. Remove that cover and there is the heater core. Open the hood and look where the heater hoses enter the front right passenger area of the exterior side of the firewall. Disconnect the two heater hose clamps and you can then remove the heater core.

Replace heater core


    A heater core transfers heat from a 1994 Ford Ranger's engine to the passenger compartment by running hot radiator coolant through a serpentine of tubing. Air blows past the hot fins of the heater core and into the truck cab.

    The hoses running to and from the heater core must be removed from the engine compartment, but the core itself is accessed from inside the passenger compartment, on the driver's side next to the center console.

    1. Turn off the engine, open the hood and remove the battery cable from the negative terminal. Make sure the engine is cool.

    2. Attach a 3/8-inch interior diameter hose to the drain outlet on the bottom rear corner of the radiator on the driver's side, and place the bottom end in a resealable plastic container. Turn the drain valve (located above the drain outlet) counterclockwise with a pair of pliers. Drain the engine coolant into the resealable container, then close the valve by turning it clockwise. Remove the hose from the outlet.

    3. Loosen the hose clamps on the radiator hoses where they attach to the heater core on the firewall. Remove the hoses.

    4. Unscrew the screws holding the underdash cover in place on the driver's side of the passenger compartment. Remove the underdash cover.

    5. Unscrew the four screws on the cylindrical heater core access cover and remove it. Remove the heater core by pulling it down and toward the rear of the vehicle. Replace the unit with a new heater core.

    6. Reinstall the heater core access cover and screw in the retaining screws. Replace the underdash cover and screw it into place.

    7. Replace the radiator hoses on the heater core in the engine compartment. Tighten the hose clamps. Add coolant until the level is between the minimum and maximum marks on the reservoir.

    8. Replace the battery cable and start the engine. Check the system for leaks.

Windows get like a foggy film and smells like old antifreeze. i think its my heater core? its a 95 bronco & where is it located exactly on that model?


Dear Foggy Film......
You are correct!!! This foggy film is the result of the antifreeze leaking and then evaporating inside the cab of the vehicle. The heater core on this vehicleis located inside the evaporator case inside the vehicle's cab on the firewall up underneath the dash closer to the passenger's side. It involves about three hours labor to replace the heater core.This is a moderate to mildly intensive repair for the first timer..if you have any more questions then you're more than welcome to get back to me!!!! HOPE I COULD HELP!!!
