A/C question

The A/c isn't working in my Jeep (4.0L ZJ) What I can tell you is when i turn the A/C button on the clutch engages for about 1 second then turns off If i try to bypass the accumulator the clutch engages but still no cold air. I have pressure in the low pressure line and I believe in the high side to. Can't find any leaks and no drop in pressure on the low side. Do you think it could be just the accumulator or something else all together?

Thanks,
PhoenixZJ

I checked the charge. it's within the parameters of what the low side should be set too. I cant check the high side just because I don't have the correct fitting.

How did you check it if the clutch won't stay engaged?

I tried with everything connected and it just turned on then off, When I took out the accumulator sensor and bypassed it with a cable the clutch started spinning and stayed spinning or engaged.

Sounds like you bypassed the low pressure safety relay that protects the compressor from burning up, refrigerant cools and lubricates the compressor, if it's low the compressor will burn up so never bypass that safety.

You plug in the meter to your low side, and measure it when the clutch is engaged. The recharge kit explained this all Except that the clutch don't stay on... That's why I had to find the video for myself.
