How do you reconnect the heater AC control cable to the control arm on a 1999 Ford Escort?

I have a 97 that should be similar. I'm confused by your term heater / AC control "cable". Mine has a vacuum hose cluster to control the dampers for AC/ defrost etc. The temperature control though is a cable which is accessible behind the cover pannels next to the gas pedal. Remove them by taking out the push pins (center head is like a nail head that has to be pulled out a little then the whole push pin will come out.) I am here looking for an answer to how you remove that cable from the operator arm. The details are avoided in the Haynes book other than to "remove" it. Lotsahelp! It is ont obvious to me what to undo, or how. The whole mechanism is covered by a plastic cover that the opoerationg cable fits up into. If you figure it out let me know. I just figured out the damper control cable while working on my radio. The cable runes from the control knob below the radio to the damper which is next to the gas peddle I took out my radio an when doing so pulled the cable off the back of the control knob. When putting the radio back I found that the cable was to short to allow you to get your finger in to reconnect it before reinstalling the radio. I tried going through the access panel as indicated above but that just gave me a visual with no way to reach up there. I then realized I must disconnect the cable from the damper end such that I can reconnect it to the radio/control knob end while the radio is out. The end at the damper actually just slid off the stem when I pried it with a screw driver. Then reconnected by simply pushing it back on. As for the control knob end it clips into place with 2 tabs and the spindle for the gear pokes through a hole. After making this connection but prior to replacing the radio check the operation of the knob. The cable limits the rotation of the knob so make sure that the knob is giving you the proper range of motion. I think there were about 7 clicks in either direction. When I first hooked the cable to the knob, the knob only rotated 3 clicks to the cool side so I counted the total clicks in the range of motion then clicked it to the middle of the total clicks , disconnected the cable, turned the knob to pointing straight up and reattached the cable. Next I reinserted the radio, then connected the cable to the damper.

Remove the radio/heater control module. Disconnect the temperature control cable at the base of the control assembly . It is on the center mound just to the right of the gas pedal. Take the heater control cable off of the back of the heater control module. Pull the temperature control cable off.

Low coolant? Thermostat not opening? Control cable not working? Plugged heater core? Heater core "airbound"? Low coolant? Thermostat not opening? Control cable not working? Plugged heater core? Heater core "airbound"?

The heater control valve is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced

No cable, all controls are done with electric motors.

Heater Airbound? Heater control cable not working? Heater core plugged?

I have a 2000 zx2 and it has a thermostat, if that is your question. Having said that, my heater quit working and it turned out to be the cable came loose under the dash on the left side of the radio. At first I thought it was the thermostat but was wrong. Duct taped the cable in place and the control and heater started working fine again.

The first thing to check is the heater control cable: has it come loose, or broken? On the engine side of the firewall, you will find the heater control valve. It's got heater hoses from the engine running into it, and it's got a lever with a pin sticking out the side of it. Ideally, there should be a cable attached to the pin. There's also a clip to hold the cable's sleeve. If the cable's not hooked up, which I fear is the case, start by going in your car and setting the heat to "high." IIRC the cable will be retracted all the way. If it is, lift the lever all the way up, push the clevis at the end of the cable over the pin, and make sure the cable is locked into the clip. If it's all the way out, push the lever all the way down before you reconnect the cable.

It does not use a cable. The heater blend door is operated by a electric motor. The complete dash assembly needs to be removed to gain access to the unit.

The heater is controlled by the same panel as the fan switch. The temperature is controlled by a cable that moves an airflow control door inside the HVAC housing. There is no water control valve if that is what you are looking for.

Disconnect positive cable first then negative. Reconnect the negative cable first then positive.

The most likely reason that the heater control won't change the air flow is that the cable that moves the diverter valve has broken and will need to be replaced.

It is at the rear of the intake manifold, follow the heater hose. there is a flow door under the dashboard with a cable connected is that the control or does the valve body at end of intake still control it?

Low coolant? Bad thermostat? Heater core plugged? Heater core airbound? Temperature control cable not adjusted properly?

it's the cable that connects your heating/cooling temp slide switch to the heater box inside the engine. If it's broken you will have no temp control.

Make sure your heater control knob is not cracked, or it will just be slipping on the shaft. Also inspect the attachment where the control cable attaches to heater control valve (underhood). You can adjust the tension of the cable by pressing on the tin part that holds the cable sleeve in position. IF you have done the above, there are a couple of other possible faults: 1) Faulty thermostat (stuck open) 2) low coolant levels or other cooling system problem

Check coolant level? Heater core plugged or restricted? Heater core airbound? Bad thermostat? Water pump not circulating coolant? Heater control cable not adjusted properly?

It does not. It is cable controlled thru a "blend door". If you are having no heat, it could be because of a clogged heater core, or the cable has came off the blend door, or the blend door control.
