Is there a reset button on air conditioning units?
But if you’re wondering where is the reset button or switch on the air conditioner unit, look for a small and red button or switch on the air conditioner. If you don’t find any reset button, your AC probably doesn’t have one, and to reset your air conditioner, you’ll have to do it manually.
What happens when an AC control module fails?
When a module is beginning to fail, air may blow only out of certain vents or under certain settings. Since the AC control module is basically the control computer for the AC system, any problems with it will negatively affect the entire system.
When does the a / C compressor start to work?
Once you turn on the AC the center part of the compressor, the AC clutch should engage and start to rotate with the pulley. The serpentine belt rides the A/C compressor pulley every time the engine runs, but the A/C compressor is working only when the A/C clutch engages it.
How does the AC Control Module work in a car?
The AC control module is used to control and regulate all the functions of the AC system electronically. It reads data from the cabin and the outside of the vehicle and uses that information to regulate and adjust the AC system as needed to keep the cabin at the correct temperature.
Why is my a / C compressor not working properly?
If that unit detects an error it will not engage the A/C compressor to avoid it getting damaged. One other reason why the A/C compressor does not engage is the fact that the system may be low on R134 refrigerant. Typically older cars may have very slow leaks that may require top off with refrigerant every couple of years.

How is the output of a compressor controlled?
The control unit uses a PWM (pulse width modulated) signal to the compressor control solenoid to vary the output level of the compressor. We have had mechanical control valves in the V-5 and V-7 compressors that ramped up or ramped down the compressor function based solely on suction line pressures.
