I have 98 k1500 that lost all of it’s refrigerant. I haven’t driven it in a while and high side developed a leak. I replaced the AP connector and drew a vacuum on the system To charge it, and make sure it didn’t have any leaks. The truck shows to take 2lbs of r134a. I had 3 12 ounce cans. It took the first two cans just fine. The compressor started cycling. I got to the third can and I couldn’t get any more in the system. I was looking to add another 8 ounces. Any ideas why it would stop taking freon after two cans went in successfully? The compressor has been changed a couple of times by a dealer over the years. Could it be that replacement compressors take less Freon and it stopped when it got full. That doesn’t seem right, but I normally don’t work on the AC. Thoughts?
