Programmer Description
The heater and A/C programmer is attached to a bracket. The bracket is located next to the right end of the heating, ventilation, and air conditioning (HVAC) module assembly, behind the glove box. The heater and A/C programmer provides the controls for temperature regulation.
The heater and A/C programmer controls an electric actuator. The electric actuator adjusts the air mix valve position in order to blend cold and warm air. Vehicles with dual zone (CJ2) have 2 electric actuators that mix the air independently of each other. The motor is reversible and moves a rotary shaft which drives the air mix valve link. The motor also provides a position sensor signal in order to monitor the actual valve position.
The heater and A/C programmer operates the 4 vacuum solenoids. The solenoids control vacuum to the various vacuum actuators. The vacuum actuators control the following components:
• The air inlet valve
• The A/C DEFROST valve
• The UP/DOWN valve
The heater and A/C programmer also controls the park brake release actuator. The powertrain control module (PCM) sends a Class 2 serial data message to the heater and A/C programmer whenever the transmission is shifted out of PARK or NEUTRAL. The heater and A/C programmer will then supply vacuum to the park brake release solenoid, which releases the park brake.
The heater and A/C programmer sometimes is referred to as the air control module (ACM). This reference is commonly used by a scan tool and by the diagnostic trouble codes (DTCs).

Hi, Common issue is the 'blower resistor' going out. You can usually buy the part @ an auto parts store or @ the dealer. The dealer should know where it's located - I do not.
Some times, you have to replace the entire blower motor. View this LINK for info.
Yes u have a leaking heater core, below fin d the instructions to replace it. 1997-2000 Ford Windstar 3.8 Heater Core Inspect ' Replace Drain the cooling system
Heater Housing
The heater housing is usually under the dash and must be removed to gain access to the heater core. Procedures for replacing the heater core vary with the year, make, and model of car. It is therefore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement. The heater housing is disassembled to get to the heater core. Heater Core Remove the access panels(s) or the split heater/air conditioning case to gain access to the heater core. Remove the heater coolant hoses. Remove the cable and/or vacuum control lines (if equipped). Remove the heater core securing brackets and/or clamps. Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing. To reinstall the heater core, reverse the removal steps. When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.
Behind the vacuum heater controls in the dash, they lead to a relay mounted there. That was the relay that was bad on my Dodge. It was a digital readout one.
In my 1985 corvette the battery is located under the hood, but you must remove the panel on the driver's side to gain access to the battery. Hope this helps
They are on the passenger fire wall .its one of the easier things to remove./You might have to loosen a strut ort sguare bar above it.Just remember to dissconnect the baterry befor you start pulling out stuff.1 check your fuses ,then check the moter relay by by bpacing it with some direct currant to make sure the fane is realy the problem.
