Same answer as the 97 escort question.
the ircm is a a module that houses relays that control operation of the a/c clutch , cooling fans and fuel pump.it is located under the air filter case.
On my '93 ford escort 1.9L, it is located under the dash, behind the heater control assembly.
You have to remove the bottom radiator hose.
doesnt have one
On the Escort the ecm is called the pcm (power control module). It is located in the console inside the car just below the heater controls.
The idle air control valve on a 1990 Ford Escort is located on the intake manifold. An idle air control valves function is to control the amount of air that is allowed to enter the engine so the idle can stabilize.
There is no heater control valve fitted on a Ford Escort. The heater matrix is directly connected to the engine's cooling system. To reach the heater matrix, you should remove all the facia unfortunately... :(
There is no temperature control switch for the cooling fans. The PCM Power control module receives input from the temperature sensor on the water outlet housing. The PCM turns on the fans when the temperature reaches 210 degrees through the CCRM.
It is located under the intake manifold between the engine and the firewall.
The PCM is located under the console towards the dash. Take console out.
Driver side front of car in the main fuse box block. Its marked.
Where is the computer located in a Ford Escort?
The high and low cooling fan relays in the 98 Ford Escortr are loacated in the CCRM (Constant Control Relay Module) which is located on the base of the drivers side strut tower underneath the air filter module. It is a small box with quite a number of wires running into it. It controls the fans, the AC compressor and the Power Control Module.
The fan has two different ways to turn on in the Escort. Check the temperature gauge and its circuit as these control the fan when the engine heats up.
You have an idle air control valve and you also have a throttle position sensor. They are both located and the throttle body.
where is the idle control motor for a 1998 ford escort
As many people as the Escort Official can effectively control
The sensor that turns it on is on the water outlet. This sensor sends information to the Power Control Module (PCM) and it in turn sends a signal to the Constant Control Relay Module (CCRM) under the intake housing which turns on the cooling fan on high or low depending on if the A/C is on.
Check Related Link below. It shows you a picture too.
It's on the wiper control switch on the multi-function switch.
The coolant temperature sending sensor on 1.9L & 2.0L engines (on '96 and earlier) are located on a cooling tube or into the themostat housing (usual position).
There is an engine temperature sensor that operates the cooling fan.
In the center console forward of the shifter and dual cup holder.
