I have a '96 contour 4cyl auto. Turned the heater on the floor position, worked fine. Turned it back to defrost and it still worked fine, but now no matter where I turn it to it only comes out at defrost even if it’s at the floor position. What could be the problem, would appreciate any help..................................Mike

Change the heater

1.
Step 1

Lift up your car's hood and locate the heater core. If you are not sure where the core is located, an auto parts store employee or a repair manual can help.
2.
Step 2

Remove the screws or bolts that hold the heater core in place. You may need to remove other parts of the car before being able to access the heater core.
3.
Step 3

Disconnect the intake and outtake hoses from the heater core. You may need a special tool to remove the couplings that connect the hoses to the heater core; refer to your car model's repair manual.
4.
Step 4

Remove the heater core. Be careful not to tip the core over, as coolant will leak out.
5.
Step 5

Reconnect the upstream and downstream hoses on the new heater core in the same matter that they were attached to the faulty core. Leaks can occur if the hoses are not connected properly.
6.
Step 6

Screw or bolt new heater core in place. Finally, replace all of the removed car parts.
