When I put the freon in it said to purge the line but the gauges I had didn't seem to have that so I hooked the freon can to it let it come out for a few seconds the plug it to the low port to fill it.

How do I test if the compressor is working? What do I need to test it?

you got to check if the clutch engages and spins the compressor. When its working you will see the high side pressure go up around 150-200 and the low side around 40

The outer end of the compressor when not working won't be spinning with the belt. When on the outer end will move with the belt

- Tue May 20, 2014 2:57 pm #345753 I had an issue like this once. Is the system R-134 from the factory, or has it been converted from R-12?

I had a leak I couldn't detect for the longest time. Turned out to be a leaky valve in the conversion kit. I had to fiddle with mine before it sealed, but what I really need to do replace the screwed on parts.

Look for dye around the valve when you pull the caps off, or look for bubbles. If it's a strong leak, you'll see it bubble out. If it's a slower leak, you could spray some soapy water on it and it'll bubble.

Still couldn't hurt to check the valves for leaks either way. I've had to replace a few when I worked at the Honda dealership on R134 systems.

Other common places i've seen leak are the o-rings connecting the lines to the compressor and the condenser.

These things. They are screwed inside under the caps on both the low and high side. They are exactly like the valves inside the valve stems in your wheels/tires.

Sometimes they back out, and sometimes the seals fail.
