You have a broken temp blend door in your heater/AC case. The reason it blows cold when you switch to MAX is because in the MAX position, the heater control valve shuts off coolant flow through the heater core. You will need a new heater case, because the door is inside the case and is not available separately. You had better replace the blend door actuator as well, because that is what I have found is causing the door to break to bgin with. The stops wear out in the actuator so that it begins advancing too far in one direction or the other and it breaks the doors.
It over heats
Remove the temperature control switch wiring harness. Remove the temperature control switch retaining screws. Reverse the process to install the new temperature control switch.
A coolant system temperature sensor controls it. : CHILTON calls it the cylinder head temperature sensor. Some after market manufacturers call it the coolant temperature sensor. These are equivalent.
The temperature control module for a 1997 Ford explorer is the unit that controls all of the heat and ac functions. If it is not operating properly, then the heat ac and defrost will work improperly or not at all.
It will blink until the waterbed is upto the temperature that it is set at.
On most models, the Idle Air Control (IAC) valve is located on the throttle body.
Its located on the back of right cylinder head ...fun too get too.....
Trouble code P0125 means:Insufficent coolant temperature for closed loop fuel control
I believe it is a blend door actuator. The blend door actuator "blends" hot and cold air enabling you to control the climate control temperature.
just the slave cylinder, for your brakes.
Replace the cruise control deactivater switch which simply screws into the top of the master brake cylinder. Costs less than $20 and everything will run properly again! there is no deactivater switch on the master brake cylinder on a 2003 ford f-250
why is it important to control temperature during of dimension
