Did you take a pressure reading before you started the Sub? I'm pretty sure there is a cutout so the compressor won't come on if there is no pressure in the system. As you fill it and it reaches the required pressure, it will come on. If the system is flat empty, you probably (but not necessarily) have a good size leak. For example, I bought an 89 Chevy pickup 5 years ago. AC didn't work. Put two cans of R134 and drove it for 3 years. AC worked great. Never added any more.When you hear hoofbeats, look for horses not zebras.

So who knows exactly how the suburban system works? My rear air is ice cold, but my front air is warm. Last year I had to put about half a can in and it worked great all summer.99 K1500 Suburban LT "THE BEAST"
