Why is the clutch on my Toyota 4Runner not working?
Make and Model > Toyota > 4Runner > AC compressor clutch won’t… If the AC compressor clutch won’t engage on your late model Toyota and you find a B1479 Flow Control Circuit trouble code stored, the problem is usually a bad flow control sensor. Toyota uses the AC flow control sensor to detect the amount of refrigerant flow through the compressor.

What to do when Clutch won’t engage?
So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…
What causes a broken clutch on a car?
Broken motor/transmission mount Clutch fails to engage properly A clutch that doesn’t engage fully, or slips under heavy load, is the normal failure mode of a worn out friction disc of pressure plate that has lost its tension. When you press the clutch, your foot counters the diaphragm spring which presses the friction disc to the flywheel.
Why is my AC fan running but the compressor is not working?
A working AC will provide you with nice and cold air as opposed to bearing the brunt of warm, dry air. With how much the HVAC runs, something is bound to go wrong with its compressor. However, having the fan running but the compressor not working is nothing too dire, so don’t panic.
What to do if your a / C compressor won’t engage?
HOWEVER, if you cannot turn the compressor on, you cannot recharge your AC levels (grrrr). So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…
How does the AC compressor work in a Toyota?
Toyota uses the AC flow control sensor to detect the amount of refrigerant flow through the compressor. Based on the reading, the ECM can adjust idle speeds and engine load parameters to save gas. The AC flow sensor converts flow rate to a voltage that’s sent to the AC amplifier which communicates digitally with the ECM.
