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 !”
What should I do if my AC compressor is not working?
The high side and low side pressure of the AC system would be the SAME (equal) when the compressor is inoperative – not working. Verify system is correctly charged. When compressor fails to engage, check pressure switch and AC relay and AC fan relay.
How does a bad AC compressor affect your car?
Every air conditioning system of a vehicle depends on a steady flow of refrigerant to circulate through it.

Why does my AC compressor clutch not engage?
Why AC clutch won’t engage 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. AC compressor clutches receive power in a number of ways.
What happens if you run a compressor with no oil?
At that point you’re running the compressor with little to no oil. You may get it to accept a charge, but you may have already damaged the compressor before the system reaches full charge. NEVER try to bypass the low pressure switch. Doing so will force the compressor to run with inadequate oil and can destroy the compressor.

What should the pressure be on the low side of the AC?
The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi. But if you see the AC low side high, high side low, such as the low side is 100 and the high side is 150, there might be problems with any of the inner components.
What does low side pressure on compressor mean?
Static low side pressure won’t give you any idea of system charge. You could have a low side target range of 50-psi and see that static pressure on your gauge. All that tells you is that there is some refrigerant in the system. But 1 ounce of refrigerant will provide a 50-psi reading the same as a full system.
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…
Can a low pressure switch cause a compressor to go off?
