How do you clutch a gas Jetta compressor?
Remove alternator, remove 2 bolts for compressor then pull the compressor up so that clutch faces towards you, then tie the compressor in that position with a wire or rope. Will this procedure work for a gas Jetta?
What’s the duty cycle on a Volkswagen a / C compressor?
3. Verify an approximate 70% duty cycle from the A/C pressure sensor at pin T14/2 (white) with the ignition on and the compressor not running (duty cycle will decrease as the high-side pressure increases).
How to loosen the clutch on an AC compressor?
5. in picture #1 you can see two long bolts that hold AC compressor, you can use 16mm deep socket with 3/8 drive from the top to loosen top bolt and the same for the bottom bolt but from the bottom side. (you don’t even have to remove the plastic side splash shield and the plastic cooler hose).

How do you replace a temperature sensor on a Jetta?

What causes a / C to work on a VW?
Note: Pin T14/3 will be grounded by the ECM if the throttle basic settings are lost. Raising the engine rpm over 2,500 will cause the ECM to allow A/C operation if this is the case. If a ground condition exists on pin 3, perform a throttle basic setting procedure and recheck for correct voltage.
