The AC heater programmer, also known as the climate control module or HVAC control unit, is typically located within the dashboard of a vehicle. It is usually mounted near the center console, behind the climate control buttons or touchscreen interface. Accessing it often requires removing several panels or components, depending on the vehicle's make and model. Always consult the vehicle's service manual for specific details regarding location and access.
To replace the AC programmer on a 1997 Cadillac Eldorado, first, disconnect the negative battery cable to ensure safety. Remove the dashboard trim panels to access the AC control module, typically located in the center console area. Unplug the old AC programmer and install the new one by reversing the removal process. Finally, reconnect the battery and test the AC system to ensure proper functionality.
Like most cars. The heater control valve is located inside the closed compartment with the heater core and the and the AC condenser. It is a door flap that seperates the heated air from the outside air, or the AC air.
AC and heater are 2 different systems. The heater works by channeling fluid from your radiator to a heater core usually located under your dash. Heater may not work due to blockage in the line from the radiator or the heater core under your dash may be faulty.
If you are looking for what is called the a/c and heater programmer its located on the passengers side behind the glove box.........
It'll have an HVAC compartment which contains the heater core, blower fan, and AC evaporator. It'll be located (or partially located) under the dash next to the passenger door AC vent.
The heater core is located in the dash ,or should I say in the heater /ac plenum if you chase out the heater hoses from under the hood you'll get a general idea where it is located.
Located at the evaporator inlet which is under the dash in the heater/AC housing.
under the glove compartment I was told!
Under the dash in the heater?AC housing.
Any of the following.................. 1. A bad a/c heater programmer. 2. A vacuum leak. 3. A bad a/c heater controller. 4. A bad interior door actuator
The heater core and AC system aren't connected.. the only component of the AC system located near the heater core is the evaporator.. so long as you don't try, say, prying out the heater core carelessly, there's nothing it should do to the AC system.
Why does your ac and heater fan turn off and on
