Why is the AC compressor clutch not engaging?
I have done some preliminary diagnosis on it and could use some advice. The compressor clutch is not engaging no matter how long I watch it on a 70 degree day with AC set to max. I have verified the controls are moving the actuators on the blend door and the blower is changing speed ect…
Why is the AC compressor on my Nissan club not working?
OP — “compressor not working.” “i check the hi side and the low side pressure. the low side was about 70 it’s too hi and the hi side was 130 i connect a wire from my vehicle battery direct to the ac compressor s wire to jump it but nothing happened not engaged !”
Why is the clutch on my Nissan Versa not working?
The clutch failed to activate during the door switch computer test, it did not engage when directly supplied with 12v when jumpered to the battery, and now it measures Infinity measuring across the two pins on the compressor meaning it definitely has a bad coil or something internal. That just sucks.
Why is the clutch not engaged on my Nissan Red?
The low pressure side does not get cold and when I hooked up the cheap can of Freon gauge to it, it went to around 85 or 90 psi in the red without the clutch engaged. Today I hooked up my manifold set and confirmed 90 psi on both the high and low side, still no clutch.
What causes an AC compressor to not engage?
And given the description of the work the other guy did, he may have damaged something along the way (let’s hope not). If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout.

Why is the clutch not working on my Nissan?
1. The pressure in the system is correct, there are no leaks. 2. The pressure sensor has been replaced by a part obtained from the dealer. 3. The IPDM has been upgraded to the new one (apparently the clutch relay is part of the IPDM itself, it doesn’t have a replaceable relay, you have to replace the whole assembly).
What happens if the clutch is not engaged?
If it judges compressor can be turned ON, it sends compressor ON signal to IPDM E/R, via CAN communication line. Upon receipt of compressor ON signal from ECM, IPDM E/R turns air conditioner relay ON to operate compressor. Kind of what I feared, a bunch of sensors that the computer uses to determine if the clutch can be engaged or not…
Why is the a / C not working on my Nissan?
The IPDM has been upgraded to the new one (apparently the clutch relay is part of the IPDM itself, it doesn’t have a replaceable relay, you have to replace the whole assembly). All fuses in the engine compartment and inside the cabin are good. 4. If you run power straight to the clutch the A/C runs cold all day long.

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…
Why does the clutch not engage in a low pressure car?
If the PCM (powertrain control module) senses low pressure in the low pressure fluid line, it will stop the compressor clutch from engaging to prevent any damage. This is because low pressure = low fluid, and r 134a is also oil/lubricant for the compressor and if you don’t have fluid then you will damage the compressor.
