On my '89 Tempo, heater controls are held into the dash kinda like how the radio is held in. Since I don't know of a tool to remove the heater controls like the one for the radio, I stuck something into each hole to hold back the clip. A bit of wiggling and I had it out.
Pull the front dash bezel out that surrounds the cluster and the radio and the a/c-heater controls out and then remove the controller and replace the switch.............
# Disconnect negative battery cable # Drain the cooling system # Working in the engine compartment disconnect the heater hoses from theheater control valve # Remove instrument panel and the center console # Remove the heater controls and disconnect the heater hoses under the dash where they connect to the heater core # Label and detach the air ducts,wiring and controls still attached to heating unit # Unbolt the heating unit and detach it from the car # Remove the screws and clips and separate the two halves of the housing.Take out the old heater core and install new unit
Yes, the overhead heater controls do light up.
The bulbs can be replaced for the radio and heater controls on a 2000 Windstar SE by removing the plate over the heater controls. Some models need an Allen wrench for this and some models will need a Star wrench to remove the screws holding this plate on.
There are no shortcuts for this repair. You have to remove the entire dash. Its located on the pasenger side behind the dash just above the radio and climate controls.
To remove the heater core you have to first rmove the bottom dash panels under where the heater controls are then pull the black box that is pu under the dash and the heater core is under there right where the hose comes through from your thermostate
remove the stereo remove the hazard switch and the rear defroster switch their is one Phillips screw under each switch remove the climate cable underneath on the heater box remove the center cluster completely buy pulling or prying out the bottom clips unscrew the climate controls from the center cluster
you'll have to remove some of the "pretty" plastic parts and get at the back of the control to find the bulb.
The heater resistor is quite simple to change. Unplug the wiring harness from the heater resistor. Remove the heater resistor retaining screws. Reverse the process to install your new heater resistor.
pull all the knobs for your heater controls off, remove 2 Philips screws pull heater bezzel out (not off completely) then you can pull the radio bezzel off. remove screws and pull stereo out. infinity stereo the amplifier is under the drivers seat.
To get to the bulb for lighting the heater controls, the front panel will have to be removed. Depending on the type of vehicle, the knobs might have to be popped off first. It is also possible on some vehicles to get to the lighting for the heater controls from under the dash.
to replace a heater core first drained cooling system. then disconnect heater hoses located on firewall at back of engine compartment. then go inside vehicle. if you have a console you will want to remove it for easier replace of core. then take off heater core cover, this is located behind heater controls, but just a little lower. there will be 6 or 8 7 mm head screws to remove. the cover is also sealed so it will take a little effort to remove. finally remove the retainer bands from core to remove. that should it. good luck!!!
