A/C system not blowing cold air

There are a couple things that cause this, but it sounds like with the testing that you did narrow it down to a compressor.

If the compressor clutch is engaging and disengaging, then most likely the compressor is failed.

Basically, if you have equal pressure on both sides of the system when the compressor is on and off then the compressor is not building any pressure.

So, I would suggest replacing the compressor and the receiver dryer. Anytime you have a compressor failure you want to replace this as well because if the compressor released metal in the system, then it will get stuck in the dryer. If you don't replace it, then it will slowly release this into the system and damage the new compressor.

You will need to evacuate the system which will pull out any metal from the test of the components.

Then when you charge the system again, you should be just fine.

I am attaching a chart below that will help with showing this as well. When the compressor is on, the low side should be around 35 and the high about 160 PSI. You have high on the low side and low on the high side which is normally a faulty compressor.

However, the give away is that the pressures don't move from static pressure when the compressor is on. Which means it is not working.

Let me know if you have questions. Thanks

Thanks for reading the guide. I will check that out because I didn't notice it and pass it on to the site admin.

Thanks again for the update.
